Honing of wafers. [Known Technology] In the honing of semiconductor wafers, the decision to achieve the purpose of honing to end the honing of the honing can be made on the basis of the time obtained empirically. However, there are various materials that constitute the honing surface, and honing time is completely different depending on those materials. In addition, the material constituting the honing surface can be imagined to have various changes in the future. Furthermore, the same applies to a slurry and a honing apparatus used for honing. Therefore, in various honing, it is very inefficient to obtain honing time from each of them. Regarding this, in recent years, for example, it has been disclosed in Japanese Patent Laid-Open Publication No. 9-7 9 8 5 and Japanese Patent Laid-Open Publication No. 2 0 0-3 2 6 2 2 0 to directly measure the honing surface. The study of the optical endpoint detection device and method of the optical method of the state is being developed. This optical endpoint detection device and method are generally disclosed, for example, in Japanese Patent Publication No. Hei 11-512977, etc., and are formed on a honing pad by a hard and uniform resin that can transmit light for endpoint detection. For a window that does not have honing ability, only this light is used to measure the honing surface. This window does not have honing ability, and does not have the size and size of the paper particles to absorb and transport.

However, in the above-mentioned honing pads, since the window does not have the honing ability, the honing performance of the honing pad may be reduced. In addition, since the slurry has no ability to hold and discharge the slurry, there is a possibility that unevenness may occur due to the installation of the window. Therefore, it is difficult to increase the number of windows, increase the number of windows, and arrange them in a ring shape. [Summary of the invention] The present invention aims to solve the above problems, and aims to provide a semiconductor wafer for honing semiconductor wafers using an optical endpoint detection device without degrading the honing performance and transmitting light for endpoint detection.

The honing pads for honing semiconductor wafers were reviewed, and it was found that even if there is no honing pad with a small window formed of a resin with high transparency as is conventional, the material constituting the honing pad itself is transparent, and the window This unit can ensure sufficient permeability. With this type of honing pad, the end point of honing can be detected by an optical endpoint detector. In addition, since the base block constituting the honing pad contains inclusions, it has been found that sufficient light transmittance can be secured even if light is scattered. In addition, it was found that even if a hard and uniform resin that does not have the ability to retain and discharge slurry, if a light-transmitting transparent member is used as a window, sufficient light-transmitting property can be ensured.

Water-soluble particles The pores formed by dissolution or detachment are buried. In addition, excessive fluffing of the surface of the honing pad can be prevented. Therefore, the holding property of the slurry at the time of honing is good, and the holding property of the slurry by dressing is easily restored, and further, the occurrence of cracks can be prevented. Examples of the bridge polymer include resins such as polyurethane resin, epoxy resin, polypropylene-based resin, unsaturated polyester resin, vinyl ester resin other than polypropylene-based resin, and 1,2-polybutylene. Diene-based elastomers such as diene, butadiene rubber, isoprene rubber, propylene-based rubber, acrylonitrile-butadiene rubber, styrene-butadiene rubber, ethylene-propylene rubber, silicone rubber, Cross-linking polymers such as fluoro rubber, styrene and isoprene rubber, and cross-linking polymers such as polyethylene and polyvinylidene fluoride in the presence of a cross-linking agent or by irradiation with ultraviolet rays or electron rays Wait. Alternatively, an ionomer or the like may be used. \ ί (Please read the precautions on the back before filling out this page) Among these bridging polymers, it can provide sufficient light transmission, and it is stable to the strong acids and alkalis contained in many slurries. This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) 11 I2211Q5__ A7 B7 V. Description of the invention (9) Absorption: There is less softening caused by water, so it is bridged by 1, 2-poly Ding Ercan is particularly ideal. This bridged 1,2-polybutadiene can also be used in combination with butadiene rubber and isoprene rubber. The method for imparting light transmittance is not particularly limited. For example, it can be performed by controlling the crystallinity and the like. In addition, the above-mentioned water-insoluble base material can only impart light transmittance to the stomach (regardless of the transmission of visible light). It does not need to be transparent (including translucent), but it is better to have higher light transmittance. It is better to be transparent. When such a water-insoluble base block material is broken at 80 ° C in accordance with JISK 6 2 51, the test piece formed by the water-insoluble base block material can be extended after the destruction (hereinafter , Which is simply called "damage residual elongation") is less than 100%. That is, it can be regarded as a water-insoluble base material whose total distance between the marks of the test piece after the damage is less than twice the distance between the marks before the failure. The residual elongation at break is preferably 30% or less, more preferably 10% or less, and particularly preferably 5% or less. In addition, it is usually 0% or less. As the damage residue extends beyond 100% and becomes larger, there is a tendency that the fine surface of the honing pad is scraped or elongated to easily plug the pores during honing and surface renewal.

In addition, as for the test temperature, in actual honing, the paper size reached due to sliding is applicable to the Chinese National Standard (CNS) A4 (210x297 mm) 1221105 A7 ___B7_ V. Description of the invention (10) The temperature to 80 ° C, so proceed at this temperature. (Please read the precautions on the back before filling this page.) The "water-soluble particles" constituting the honing pad of the invention according to the first aspect are dispersed in the above-mentioned water-insoluble base material. It comes into contact with the aqueous medium supplied from the outside, dissolves or swells and detaches from the surface of the honing pad (due to dissolution or swelling, etc.). The slurry can be maintained at the detached trace, and the honing debris can be temporarily retained to form fine Porous particles 0 There are no particular restrictions on the printing of the water-soluble particles by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, and various materials can be used, such as organic water-soluble particles and inorganic water-soluble particles. As the organic water-soluble particles, dextrin, cyclodextrin, mannitol, lactose and the like, cellulose such as hydroxypropyl cellulose, methyl cellulose, starch, protein, polyvinyl alcohol, and polyethylene can be used. It is composed of pyrrolidone, polyacrylic acid, polyethylene oxide, water-soluble photosensitive resin, master polyisoprene, master polyisoprene copolymer, and the like. In addition, as the inorganic water-soluble particles, potassium sulfate, potassium acetate, potassium nitrate, potassium carbonate, potassium bicarbonate, potassium chloride, potassium bromide, potassium phosphate, manganese nitrate, and the like can be used. Among these, cyclodextrin and potassium sulfate are preferred. These water-soluble particles composed of these components may be used singly or in combination of two or more kinds. Furthermore, the water-soluble substance may be used in combination with an organic system and an inorganic system. The shape of the water-soluble particles is not particularly limited, and it is generally preferred to be closer to a sphere, more preferably to a sphere. In addition, it is preferable that each water-soluble particle has a more uniform shape. With the uniform shape of the pores thus formed, good honing can be performed. This paper size applies the Chinese National Standard (CNS) A4 specification (210'〆297 mm) -13- 1221105 A7 B7 V. Description of the invention 〇1) In addition, the size of the above water-soluble particles is not particularly limited, usually 0 1 to 5 0 0 β η 1, more preferably 0.5 to 1 0 0 // m, and more preferably 1 to 8 0 β η 1. If the particle size is less than 0 · 1 A m, the size of the pores (please read the precautions on the back before filling this page) may be smaller than the abrasive grains, which may cause the problem that the pores cannot keep the abrasive grains, which is not ideal. . On the other hand, if it exceeds 500 // m, the size of the formed pores becomes too large, and the mechanical strength and honing speed of the honing pad tend to decrease. In addition, when the amount of the water-soluble particles contained in the honing pad is 100% by volume, the total amount of the water-insoluble base material and the water-soluble particles is preferably 10 to 90% by volume, more preferably 15% by volume. ~ 60 vol%, more preferably 20 to 40 vol%. If the content of the water-soluble particles is less than 10% by volume, sufficient pores cannot be formed, and the honing rate tends to decrease. On the other hand, if it exceeds 90% by volume, it is difficult to prevent the water-soluble particles from not only exposing the surface of the honing pad, but also the water-soluble particles present inside, from undesirably dissolving or expanding. Therefore, it is difficult to maintain the hardness and mechanical strength of the honing pad at a proper honing during honing. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In addition, it is preferable that the water-soluble particles are dissolved in water only when exposed on the surface of the honing pad, and those that are not exposed but are present inside the honing pad do not absorb moisture and swell. Therefore, it is also possible to form a shell made of epoxy resin, polyimide, polyimide, polysilicate, or the like which suppresses moisture absorption in at least a part of the outermost part of the water-soluble particles. In addition to the function of forming the pores during honing, the water-soluble particles also have a function of increasing the hardness of the honing pad. For example, the hardness of Xiao D is preferably 35 to 100. As a result, the hardness of the honing pad can make the paper size applicable to the Chinese National Standard (CNS) A4 (210X297 mm) -14- 1221105 Α7 Β7 V. Description of the invention (12) (Please read the note on the back first Please fill in this page again.) The pressure on the honing surface becomes larger, which can not only increase the honing speed, but also achieve high honing flatness. Therefore, it is preferable that the water-soluble particles are solid enough to ensure sufficient hardness in the honing pad. The method for dispersing the water-soluble particles in the water-insoluble base material is not particularly limited. Generally, the materials constituting the water-insoluble base material, water-soluble particles, and other additives are kneaded. In this kneading, in order to make the material constituting the water-insoluble base material easier to process, the kneading is performed while heating, but at this time, it is preferable that the water-soluble particles are solid. With the solid, it is possible to easily disperse the water-soluble particles while maintaining the above-mentioned desired average particle diameter regardless of the compatibility of the materials constituting the water-insoluble base material. Therefore, it is desirable to select the type of water-soluble particles depending on the processing temperature of the material constituting the water-insoluble base material used. In the honing pad of the invention according to the first aspect, in addition to the water-insoluble base material and the water-soluble particles, the polishing pad containing the conventionally contained slurry can be maintained within a range capable of maintaining light transmittance. Granules, oxidants, hydroxides of alkali metals, acids, p Η regulators, surfactants, scratch prevention, employees of the Intellectual Property Bureau of the Ministry of Economic Affairs, consumer cooperative printing products, etc. As a result, honing can also be performed by supplying only water during honing. In addition, in order to make the water-insoluble base material compatible with the water-soluble particles, and to include the water-insoluble base material, The dispersibility of the water-soluble particles is ideal, and a compatibilizing agent can be blended. Examples of the compatibilizing agent include polymers, block copolymers, and random copolymers that are denatured by acid anhydride groups, carboxyl groups, hydroxyl groups, epoxy groups, and amino groups. Furthermore, this paper is in accordance with Chinese national standards. (CNS) A4 specification (210 × 297 mm) -15-1221105 A7 _B7___ V. Description of the invention 〇3) Various anionic surfactants, coupling agents, etc. These can be used individually by 1 type or in combination of 2 or more types. (Please read the precautions on the back before filling in this page.) Furthermore, the honing pad of the invention of the first aspect may contain, as required, an antistatic agent, a softener, an oxidation inhibitor, an ultraviolet absorber, and an electrification agent. Various additives such as inhibitors, slip agents, and plasticizers. In addition, reactive additives such as sulfur and peroxide may be added to cause reaction and bridge the reaction. Examples of the above-mentioned concrete fillers include materials that enhance the rigidity of potassium carbonate, magnesium carbonate, talc, clay, and the like, as well as silicon dioxide, aluminum oxide, thorium dioxide, chromium oxide, titanium dioxide, manganese dioxide, and trioxide. Materials with honing effect such as manganese and barium carbonate. These can be used individually by 1 type or in combination of 2 or more types. The honing pad according to the invention of the first aspect can be produced by introducing the composition of each component into a mold having a predetermined shape or the like. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The invention of the honing pad of the first aspect is to hold the slurry through pores, so that honing debris can be temporarily retained. The planar shape of the honing pad is not particularly limited. For example, the honing pad may be formed in a circular shape such as a disc, and a polygonal shape such as a belt or a roller. In addition, the size is not particularly limited. For example, in the case of a disk, the diameter may be 500 to 900 mm. In addition, the thickness of the honing pad according to the first aspect of the invention may be set according to the application. It is different, but it is usually 0.5 mm or more, more preferably 1 to 3 mm. The thickness of the honing pad can also be constant, or it can be set to some different thicknesses. When the end point of honing is detected by light, the standard of China National Standard (CNS) A4 (210X29 * 7 mm>) is generally applied when the light is transmitted through the paper size. -16- 1221105 A7 B7 V. Description of the invention (14) (Please Read the precautions on the back before filling in this page.) In the case of a light-transmitting object, consider the property that the intensity of the light is attenuated in proportion to the square of the length of the transmitted object. It can be set on at least one part of the honing pad Light is easy to pass through. Therefore, for example, thinning the portion where the end point of the honing is detected by light can greatly increase the transmittance, and thus improve the detection sensitivity. Furthermore, in addition to the thinned portion, In the detection of the end point, light of sufficient intensity is not easy to pass through, but the thin meat portion can ensure sufficient light intensity necessary for the detection of the end point. Therefore, it is better to have a thin meat portion. This thin meat portion is specifically formed more than the honing pad. The part with the largest thickness (for example, refer to Figures 1 to 4). The planar shape of this thin meat part is not particularly limited. For example, it can be circular, fan-shaped, square, or rectangular. As well as polygonal shapes such as trapezoids, ring shapes, etc. In addition, the cross-sectional shape of the thin meat portion can be, for example, a polygonal shape such as a quadrangular shape, a pentagonal shape, a dome shape, or other shapes (refer to FIGS. 1 to 4). It is a honing surface. In addition, the size of the thin meat portion is not particularly limited. For example, in the case of a circle, a diameter of 20 mm or more is preferable, and in the case of a ring, the width is preferably 20 mm or more. In the case of a rectangle, it is preferable that the depth is more than 30 mm and the width is more than 10 mm. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Furthermore, the number of thin meat parts to be placed on the honing pad is also particularly limited. It is one place, two places or more. In addition, this position is also particularly limited. For example, when one thin meat portion is provided, it can be installed in places such as FIG. 5 and FIG. 6. Furthermore, two places are provided. The above thin meat portion can be formed into concentric circles (refer to Figure 7), etc. The thickness of this thin meat portion is not particularly limited, and it is usually the thinnest in the thin meat portion. The paper size applies to Chinese national standards. CNS) A4 specification (210X297 mm) -17- 1221105 A7 __B7____ 5. Description of the invention (15) (Please read the precautions on the back before filling in this page) The thickness of the part is 0 · 1 mm or more, and more preferably 〇 · 3 mm or more is preferred. It is usually 3 mm or less. When it is less than 0.1 mm, it is difficult to sufficiently ensure the mechanical strength of this part. Furthermore, the thin meat part can be honed by a honing pad. The honing surface is formed with depressions (refer to Figure 2), but it is better to form depressions on the inside (refer to Figure 1). By forming depressions on the inside, it is possible to obtain good transparency without affecting the honing performance. In addition, it is also possible to form a groove portion with a predetermined width (for example, 0.1 to 2 mm), depth, and interval on the honing surface of the honing pad as needed, different from the depression of the thin meat portion, and Set the dot pattern. Thereby, it is possible to improve the retention of the slurry and to improve the dischargeability of the used slurry. These grooves and dot patterns can be formed in a predetermined shape such as a concentric circle shape, a lattice shape, a spiral shape, a radiation shape, or the like. In addition, the groove and the dot pattern may be used by the recessed portion formed to be recessed in order to form the thin meat portion. The aforementioned "light-transmitting property" is not particularly limited as long as it can transmit light. The thickness of the honing pad is 2 mm. In the case of a wavelength of 100 ~ 1, printed by an employee consumer cooperative of the Bureau of Intellectual Property of the Ministry of Economic Affairs, ^ 3 0 0 nm, the transmittance of light at any wavelength is greater than 0.1%, or the wavelength is 1 0 0 to 3 0 0 The cumulative transmittance of any wavelength band between 0 nm is preferably above 0.1%. The transmittance or cumulative transmittance is preferably 1% or more, and more preferably 2% or more. However, even if this transmittance or cumulative transmittance is higher than necessary, it is usually only 50% or less, more preferably 30% or less, and especially 20% or less. This paper standard applies Chinese national standards ( CNS) A4 specification (210X297 mm) 1221105 A7 __ _B7 V. Description of the invention (16) (Please read the precautions on the back before filling out this page) In addition, it is used for honing using the honing of the optical endpoint detector In the pad, it is further preferred that the frequency of use as the end-point detection light in a particularly high frequency band of 400 to 800 nm is high. Therefore, with a thickness of 2 mm, the transmittance of light at any wavelength between 400 and 800 nm is 0.1% or more (more preferably 1% or more, and more preferably 1% or more (more preferably 3% or more, usually 50% or less), or the cumulative transmittance of any wavelength band between 400 and 800nm is 0.1% or more (more preferably 1% or more, More preferably, it is more than 2%, especially more than 3%, and usually less than 50%). However, this transmittance or cumulative transmittance may be as high as necessary or more, and it is usually below 20%, further below 10%, and especially below 5%. In addition, this transmittance is measured by a device such as a UV absorber, which can measure the absorbance of a predetermined wavelength on a test piece having a thickness of 2 mm, and measures the transmittance of light of each wavelength. The accumulated transmittance can also be obtained by accumulating the transmittance of a predetermined wavelength band that is also measured. The second aspect of the invention is a honing pad for semiconductor wafers printed by the Employees ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, which is characterized by comprising a base for a honing pad having a through hole penetrating through the front and back, and a through hole fitted into the pad The light-transmitting member is formed by a water-insoluble base material and water-soluble particles dispersed in the water-insoluble base material. Regarding the second aspect, the "substrate for honing pads" has honing performance by itself, and maintains a slurry on its surface, so that honing scraps can be temporarily applied to the paper standard of China National Standard (CNS) A4 (210X297). (Mm) Printed by the R Industrial Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 1221105 A7 ____B7 V. Description of Invention (17) Detainees. It does not matter whether or not the substrate for the honing pad has a light transmitting property. The planar shape is not particularly limited, and may be, for example, a polygon such as a circle or a quadrangle. The size is not particularly limited. In addition, in order to maintain the slurry during honing and temporarily retain honing debris, it is preferable to form at least fine holes and grooves on the surface of the base for the honing pad. That is, micropores and / or grooves (for example, foams) can be formed in advance in the base for a honing pad, and fine holes and / or grooves can be formed by detaching during honing. Among the latter, a water-soluble material having a predetermined shape such as a particle shape or a linear shape dispersed in a water-insoluble base block material can be used. A honing pad provided with such a base for a honing pad is in contact with an aqueous medium during honing, and the water-soluble material dissolves the fire and detaches, thereby forming fine holes and / or grooves on the surface of the base for the honing pad. The material constituting the base for the honing pad is not particularly limited, and various materials can be used. In particular, it is preferable to use an organic material because it is easy to form a predetermined shape and properties, and can impart appropriate elasticity. As the organic material, a foamed material and various materials constituting a light-transmitting member described later can be used. However, the material constituting the base for the honing pad and the material constituting the translucent member may be the same or different. The thickness of the base for a honing pad according to the second aspect of the invention may be different depending on the application, but it is usually 0.5 mm or more, more preferably 1 to 3 mm. The thickness of the base for the honing pad may be constant for the whole or partly different. The "through-hole" is a surface that penetrates the base of the honing pad, and a light-transmitting member is fitted on the inside. The above through-holes can be set in honing.

The end portion may be a cutout portion. The shape of the above-mentioned through hole is not particularly limited. For example, the planar shape of the opening portion may be a polygon, a circle, a circle, a fan, a square, a trapezoid, or the like. In addition, the cross-sectional shape of the through-hole may be, for example, a T-shape, an inverted T-shape, a quadrangle, or other shapes (refer to FIGS. 8 to 11. In the figure, the base for the honing pad is represented by 12, and the through-hole is represented by 12. It is represented by 13. Moreover, the upper side of each figure is set as a honing surface side). Among them, the T shape is particularly preferable. The size of one of the above-mentioned through holes is not particularly limited. Generally, when the opening portion is circular, the diameter is preferably 20 mm or more (usually, less than 2/3 of the radius of the honing pad). In the case of a through-hole, the width is preferably greater than 20 mm (usually, less than 2/3 of the radius of the honing pad). In the case of a quadrangle, the depth is more than 30 mm (usually, at 硏The radius of the polishing pad is less than 2/3), and the transverse direction is more than 10mm (usually, it is less than 2/3 of the radius of the honing pad). If each of the through holes is smaller than the above, it may be difficult to surely transmit the light such as the end detection light. In addition, the number of through-holes is not particularly limited. The above-mentioned "light-transmitting member" printed by the Consumer Cooperatives of the Ministry of Economic Affairs and Intellectual Property Bureau means that it has light-transmitting properties that make it easier to detect the end of the honing.

Materials forming the water-insoluble base material constituting the above-mentioned light-transmitting member The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X29 * 7 mm) -21-1221105 A7 ______B7 V. Description of the invention (19) ( (Please read the notes on the back before filling in this search.) It is ideal to use the material of the water-insoluble base material exemplified in the invention of the first aspect described above. Therefore, the non-water-soluble base material constituting the light-transmitting member is preferably at least a bridge polymer, and the bridge polymer is preferably 1,2-polybutadiene that is bridged. The water-soluble particles constituting the light-transmitting member are not particularly limited, and it is preferable to use the water-soluble particles of the first aspect of the invention in consideration of properties exhibited by the size of the light-transmitting member. That is, it can be the same as the kind, shape, and structure of the water-soluble particle of the invention of the said 1st viewpoint. In addition, as described above, a shell made of epoxy resin, polyamide, polyamide, polysilicate, or the like may be formed on the surface of the water-soluble particles. When the water-soluble particles are honed, In addition to the function of forming pores, it also has a function of matching the pressing hardness of the light-transmitting member to the other parts of the honing pad. In order to increase the pressure applied during honing and increase the honing speed to obtain high flatness, the hardness D of the honing pad as a whole is 3 5 ~ printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 1 0 0 Better. However, in the case where it is difficult to obtain the desired Diao hardness of the material constituting the water-insoluble base material alone, in this case, in addition to making the water-soluble particles to form fine pores, the Diao D hardness increased to the same degree as the other parts of the honing pad. For this reason, it is preferred that the water-soluble particles are solids which can secure sufficient hardness in the honing pad. The shape of the light-transmitting member is not particularly limited. The planar shape of the honing surface side of the honing pad generally depends on the shape of the through hole, and is generally the same as the shape of the through hole. The shape can be circular or polygonal as described above. Wait. In addition, the size of this paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 1221105 A7 __B7 V.

For example, the cross-sectional shape shown in FIG. 12 to FIG. 19 may be used. 12 and 12 are honing pads showing a state where the light-transmitting member 14 having the same thickness as the base 12 for the honing pad is completely fitted into the through hole, and FIG. 13 and FIG. 5, FIG. 16, FIG. 17, and FIG. 19 are honing pads showing a state where the light-transmitting member 14 having a thickness different from that of the base 12 for the honing pad is fitted into the through hole. The light-transmitting member may not be thinned as shown in Figs. 12 and the like, but may be thinned. The so-called thinness includes, for example, as shown in FIGS. 13, 15, 16, 17, and 19, the thickness of the light-transmitting member is made smaller than that of the base for the honing pad. The maximum thickness is also thin; or, as shown in FIG. 18, the light-transmitting member itself is thin to form the light-transmitting portion. The light-transmitting member can use the properties possessed by the thin meat portion of the honing pad according to the invention of the first aspect. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, by using thin and light transparent members, the light transmittance can be greatly improved and the end point of honing can be easily detected. However, the thickness of the light-transmitting member is preferably 0.1 mm or more, more preferably 0.3 mm or more, and usually 3 mm or less. If it is less than 0.1 mm, it tends to become difficult to sufficiently secure the mechanical strength of the light-transmitting member. The number of the light-transmitting members is not particularly limited, and the number of the through holes may be one or two or more. The arrangement is not particularly limited. For example, when one light-transmitting member is provided, it can be arranged as shown in Figs. 20 and 21. Furthermore, if there are 2 -23- this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 1221105 A7 ____B7_ 5.
