Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for vapor condensation of oxygen species and recycling of vaporized oxygen elements into a vaporization element. [Prior Art] The oxygen element of the present invention is the sixth main group element of the periodic table (except oxygen). *This, the oxygen element is partially deposited on the object to be coated by physical vapor deposition (pvD). For example, an oxygen group element is coated on a substrate by physical vapor deposition (PVD). An example of the above method is disclosed in the patent number W〇2_/034131 A2, specifically, a physical grouping method (PVD) is used to deposit an oxygen group element on a substrate, which is a part of a process for manufacturing a compound semiconductor layer. In such physical vapor deposition (PVD), the oxygen element vapor is usually supplied to the (four) cloth (for example, the substrate) by the carrier gas, and the oxygen element of the conditional portion on the surface of the substrate is borrowed and borrowed. The other undeposited oxygen element vapors are evacuated by, for example, suction. Therefore, it is necessary to re-use the oxygen-containing element containing undeposited oxygen-containing voxel vapor to carry out the coating in the next step. "The oxygen element vapor which is not involved in the deposition is usually mixed and carried. Gas and/or other gases or H The present invention provides a solution to this problem. SUMMARY OF THE INVENTION 201219104 The above problem can be solved by a method which is characterized by the requirements of the scope of the patent application. The present invention also provides a device by which a method for solving the above problems can be implemented. The above problems can be solved by means of a device having the features requested in item 5 of the scope of the patent application. The preferred improvements are those of the other patent application scopes. The method of the present invention comprises: providing oxygen group element vapor into the condenser, wherein at least a portion of the oxygen elemental vapor can be condensed into a liquid oxygen groupin' and the liquid oxygen group element can be reflowed through a portion The gas trap of the pipeline is recycled to the vaporization element. A liquid oxygen species segment is also provided in the gas trap. The liquid oxygen species segment balances the pressure difference existing between the condenser and the vaporization element. Usually the pressure in the vaporization element is higher than the pressure in the condenser, and despite this pressure difference, the liquid oxygen group element can recycle the liquid oxygen group element from the condenser to the vaporization element, by gravity alone This recycling reaction can be achieved. Furthermore, in terms of economic efficiency, the liquid oxygen group element also prevents the oxygen element vapor from entering the condenser through the return line from the vaporization element. In the present invention, the 'liquid oxygen group element segment is the amount of condensation of one of the liquid oxygen group elements' which extends to the entire cross section of the return line (at least partially). For example, when the cross-section of the return line is locally narrowed by, for example, an insert, a solid oxygen element component, or any other substance, the remaining cross-sectional opening is considered to be the cross-section of the return line. 5 201219104 The tempered two-family 7L gas vapor can be cooled in the condenser by the oil installed in the condenser = fire's: the elemental " The method can be as follows: a liquid steaming > 'to the condenser, wherein nitrogen gas is used as the carrier gas 'J to supply the oxygen element vapor to the mixed alpha gas stream to: r: broadly forming - oxygen group vapor · carrier gas The mixed gas is supplied to the condenser. The pressure can be =====, specifically, the suction device can be a ventilator. Read stream = oxygen elemental vapor that is not condensed in the condenser, preferably 'supplied to - (4), using the other gas components in the mixture of oxygen and gas (eg, carrier gas) The separated gas component may be emitted as a residual gas or exhaust gas to the environment t, or, if necessary, may be further subjected to a purification step. The siphon is often referred to as the partition (4) in the English-speaking countries. The original can be any form (4). For example, the tile is separated, the "P-type gas solution", or " S-type gas barrier", preferably one: a gas trap having at least one U-shaped pipe joint (such as a gas trap or an S-type gas trap), however, the cross-sectional shape of the pipe joint is not affected limit. Preferably, helium vapor or sulfur vapor is used as the oxygen element vapor. After the condensation reaction, depending on the situation, liquid selenium or liquid sulfur is obtained. 201219104 Preferably, the main temperature of the condenser (such as the temperature of the oil tempering plate described above) is maintained at 220. (: between 300 〇C, especially preferably 27 〇 cc) The above temperature values are particularly confirmed in the condensation reaction of selenium vapor. Further preferably, the liquid oxygen group element is at least partially cured, and Forming a solid oxygen group stop of the ventricle. The above situation may occur at the end of the condensation reaction, so that the return line is continuously sealed. The long-time heating keeps the liquid oxygen group element in a liquid state. Omitted, when this condensation reaction is started again, there is no risk of oxygen group vapor entering the condenser from the vaporization element through the return line. Conversely, the solid oxygen element of the sealed gas trap of the present invention can be used. At least a portion of the child is melted to form a liquid oxygen group element. Upon initiation of the condensation reaction, it is determined that the liquid oxygen species can flow through the gas trap, so that the liquid oxygen species can be recycled to the vaporization element. The return pipeline used in the present invention is formed by a descending pipeline, a gas barrier, and a connecting pipeline. The descending pipeline connects the condenser and the gas trap, and the connecting pipeline is connected to the gas trap. And vaporization elements. The temperatures mainly distributed in the three regions of the return line can be individually controlled, in particular, the respective temperatures can be independently adjusted. By individually controlling and/or regulating the above-mentioned return line The temperature of the liquid oxygen group elements in different regions allows the flow characteristics of the liquid oxygen group elements in the respective regions to be independently controlled and/or regulated. The pipeline under the present invention is not necessarily in a monotonously decreasing form, however, - a descending side: or a downward line in the direction of an upright route. 201219104 It has been confirmed by experiments that the preferred experimental conditions are to maintain the temperature of the downstream pipeline mainly distributed at 220. (: to 27MC; maintain the gas barrier The temperature is mainly distributed between 190. (: and 270. 0: between; and the temperature at which the connecting pipe is maintained is mainly distributed between 240. 0 and 500. (: between, preferably about 27 〇〇 c. Especially, when When selenium vapor is used as the oxygen element vapor, it has been confirmed that selenium in the connecting pipe is a thin liquid because the helium in the down pipe is converted from a semi-liquid to a thin liquid (thin-liquid) main The temperature of the gas trap can control or regulate the liquid selenium flow through the gas trap. 77 - In the present invention, the liquid oxygen group element passing through the partition (four) can be controlled by the -dissolving valve. The circuit can also be used to regulate the flow of the liquid oxygen element element through the gas barrier. The melting valve is a device that can be dissolved or solidified in the form of a gas barrier to the object. t, at least some of the above objects reduce the cross section of the gas barrier tube. The change in flow can also be affected by changing the viscosity of the liquid oxygen species. Examples of the (four) valve will be described in more detail in the apparatus of the present invention. In a preferred embodiment of the method of the present invention, the liquid oxygen species flow passing through the gas barrier is opened and closed by adjusting the temperature mainly distributed in the gas trap and the temperature of the gas trap itself. It is not that the oxygenation of the oxygen species in the gas barrier is no longer flowing, that is, the oxygen element flow can pass through the gas barrier to open the oxygen element flow through the gas barrier, and then the main knife cloth can be controlled or adjusted. Down the pipeline Degree, to control or regulate the rate of liquid through the barrier gas trap chalcogen stream. 201219104 The apparatus for carrying out the condensation method of the present invention is connected to the condensation 5! and is used to include a condensation Is, and a flow line, "!ί Oxygen element moves away from the condenser back=1" This contains - The gas-repellent reflux line can make the liquid 峨 疋 至 至 & 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 Heating. "You can add two systems separately = this gas barrier _ the same heating device is separated and heated separately.

In fact, the first heating means has at least one first type of heating element disposed in a longitudinally extending position along the hollow column. Preferably, the first heating means comprises at least two first type heating elements disposed in a longitudinally extending position along the hollow column. The intermediate column μ is placed between at least two first-type heating elements, in particular, by: the heat output and the slew rate of the melting valve. Still preferably, the first type of heating reduces heat radiation to an unintended direction into the environment of the return line. Moreover, the area where the heating zone where the dissolution valve is freely contacted is at risk of being worn out. The beta element is provided with a heat insulating layer for use. The main purpose of the heat-preventing layer is to prevent the heat-insulating layer from being reduced during the heating process, thereby reducing the freedom of the melting valve. Preferably, the first heating device comprises at least one second-type additive member disposed on the outer surface of the hollow column. region. This (4) allows the hollow enthalpy cooled by the rushing of the cooling medium to be added more quickly: • The switching time between the cows is shortened.

H is an upright route 201219104. Preferably, the down pipe is designed as a downward flow pipe (d〇wnpipe), and the connection f S road is set to S is a connection pipe (c〇nnecting pipe), wherein The cross-sectional shape of the downflow tube and the connecting tube is not limited. The condenser can be connected to a filter via a filter line which filters the oxygen element vapor in a gas mixture containing oxygen element vapor. Oxygen vapor which has not reached condensation can be filtered by this filter to cause only a small amount or even an oxygen-free elemental vapor to enter the atmosphere. Preferably, the condenser is connected to a vaporization element via a return line, whereby the liquid oxygen species can be returned to the vaporization element and reused. The vaporization element can be exemplified by a graphite block of a cavity and an oxygen element which is condensed during the condensation process is placed in the cavity. A ventilator can be used to provide oxygen elemental vapor into the condenser, which can be used to generate a gas stream into the condenser. For example, a stream of oxygen-carrier gas mixture can be introduced into the condenser by a ventilator. [Embodiment] Figs. 1 and 2 illustrate a first embodiment of the method and apparatus of the present invention. In this embodiment, the apparatus of the present invention has a condenser 9 and a return line 丨7 connected to the sigma condenser 9, and the return line 丨7 can remove the liquid oxygen steroid from the condenser 9. . In this embodiment, the vapor nitrogen mixture 36 is supplied to the condenser 9 as oxygen group vapor. Here, nitrogen gas is used as a carrier gas for helium vapor. The field steam of the 201219104 code steamed nitrogen gas mixture 36 is produced by a vaporization element 1 and the liquid liquid 2 is placed in the vaporization element 1. Under an overpressure, nitrogen is introduced into the vaporization element crucible through a nitrogen gas inlet 3 and passed over the liquid selenium 2 . This nitrogen acts as a carrier gas and absorbs the selenium vapor there. As shown, the resulting helium vapor nitrogen mixture 36 then passes through a supply line 5 into a coating head 4. A part of the selenium vapor contained in the selenium vapor nitrogen gas mixture 36 is deposited on a substrate 7 in the coating zone of the coating head 4. In order to achieve uniform coating, the substrate 7 can preferably be guided under the coating head 4 at a steady speed. However, most of the selenium vapor is still present in the selenium vapor nitrogen mixture 36 and enters the condenser 9 via a feed line 8 (as shown in Figure 1, the change in the aspect shown in Figure 1 may be, the vaporization element The crucible and coating head 4 can be formed as a single component. For example, a homogeneous phase graphite block can be provided with both a vaporization element and a coating head. This coating head itself is described in further detail in German Patent Application No. 102009009022. In the present embodiment, the selenium vapor nitrogen mixture 36 enters the condenser 9 via a ventilator 14, wherein the ventilator 14 can be used to form a selenium vapor nitrogen mixture gas stream. Thus, the ventilator 丨4 is fed. A negative pressure is generated in line 8. The oil tempering plate 1 is maintained at a temperature of about 270 〇c and is disposed in the condenser. At least a majority of the selenium vapor in the selenium vapor nitrogen mixture 36 will be on the oil tempering plates. Condensed and collected in a funnel, and then returned to the vaporization element through a return line 17 (as shown by the dashed line in Figure *). The vapor that has not reached condensation is introduced into the filter line π together with the carrier gas nitrogen. filter The separator 12 is separated from the nitrogen by the filter 12, and the remaining nitrogen and other further (3 201219104 gas composition enters the atmosphere via a suction line 15 and an exhaust line 16 or is supplied to a further exhaust gas treatment. Figure 2 is a partial enlarged view illustrating the details of the return line 17. As shown in Figure 2, the return line 17 includes a gas trap 35, which in this example is designed as an S-type gas barrier. Fig. 2 also shows that the return line 17 is formed by a lower line, a gas trap 35 itself, and a connecting line, wherein the down line connects the condenser 9 to the gas trap 35, and the down line is here. The example is designed as a downward flow tube 18; the connecting line is designed as a connecting tube 2 〇. The gas trap 35 contains a U-shaped tube section 19, and the condensing tube is balanced by a liquid selenium section 21 present in the u-shaped tube section 19. The pressure difference between 9 and the vaporization element 1. The balance of this pressure difference is as shown in Fig. 2. The left side of the liquid selenium section 21 in the U-shaped tube section 19 is higher than the right side height. Therefore, 'in the vaporization element 1 is as expected. The ground is distributed with a higher pressure than the condenser 9. If it is condensed, the liquid selenium is condensed at this time. Entering the return line 17, the height of the liquid selenium section 21 rises to the right, and the liquid helium can pass over the gas trap 35'. The liquid selenium then enters the connecting tube 2〇 and reaches the vaporizing element 1. In Fig. 2, a melting valve 24 is disposed at the bend of the U-shaped tube section 19. By changing the temperature of the selenium in this area, the melting valve 24 can control the flow through the gas barrier 35. If the liquid selenium is cooled down, the viscosity increases and the flow is lowered. Conversely, this flow can be increased by heating. In an extreme case 'by allowing any selenium in the U-shaped tube section 19 to solidify or melt, in this way the flow through the gas trap 35 can be completely Suspend or start. Therefore, the flow of selenium through the return line 17 can be opened or closed by the melting valve 24. The following is explained in more detail based on the detailed Figure 3. 201219104 Figure 3 shows a solid selenium stopper 22 disposed within the U-shaped tube section 19 by which the solid selenium stopper 22 is formed to close the return line 17 (e.g., after the end of the condensation process or with respect to process interruption) . Figure 3 illustrates the situation after the device is re-operated. In the condenser 9, the helium vapor has been condensed so that liquid selenium is present in the downflow tube 18. In the U-shaped tube section 19, the solid selenium stopper 22 is subsequently melted by the melting valve 24, at least until the liquid selenium section 21 can be formed and the liquid selenium 23 can pass through the U-shaped tube section 19. This melting valve 24 represents a first heating means whereby the first heating means allows the gas traps 35 to be separately heated. As shown in Fig. 3, a second heating means 39 is provided on the downflow tube 18, and a third heating means 4 is provided in the connecting tube 20. With this design, the downflow tube 18 and the connecting tube 20 can also be separately heated. Therefore, the characteristics of the liquid helium flow in the downflow pipe 18 or the connecting pipe 20, particularly the flow velocity, can be independently controlled. For the sake of clarity, the second heating means and the third heating means are not shown in Fig. 2. Fig. 4 is a schematic cross-sectional view through the melting valve of Figs. 2 and 3, whereby it is known that the melting valve 24 includes a hollow post 28 containing a sheath 31. A bore 37 placed in the jacket 31 can be used to flush a cooling medium. Here, any cooling medium can be used, such as 'a gaseous aerosol, water, oil or nitrogen. The inlet 29 can be used to introduce a cooling medium into the bore 28. The meltdown valve 24 also has an outlet 30 whereby the outlet 30 can be used to direct the cooling medium out of the bore 28. The hollow column is disposed at a portion 25 of the U-shaped tube section 19. The portion 25 and the selenium therein can be cooled by the flow of the cooling medium through the cavity 37. The melting valve 24 also includes first type heating elements 26a, 26b disposed in a longitudinally extending position along the hollow column 28. The hollow column 28 is disposed between the 15th and 19th type heating elements 26a, 2A, and a second type of twisting element, which is disposed on the outer surface area of the hollow column 28, and is larger than the first The unit area of the heating elements 26a, 26b is thermally outputted. Therefore, the jacket 31 cooled by the cooling medium can be heated relatively quickly. The first type heating elements 26a, 26b and the second type heating element 32 are formed together. The first twisting device 26a, 26b, 32' allows the gas traps 35 having the first heating means w, say 32 to be heated separately. The second type heating elements 26a, 26b ± provide a heat insulating layer 27 Used to reduce unintended thermal radiation into the environment, and at the same time, to protect against contact. The second type heating element 32 and the hollow (four) are covered by the outer casing 33 as a means to prevent any hollowing element (second) from the second heating element 32. Protection against contact. This enclosure 33 acts to prevent inadvertent contact with the second type heating element 32, the heat insulating layer U, and the hollow post 28. A temperature sensor 34, which is disposed on the inner surface area 31b of the hollow post 28, may include, for example, a Thermocouples, like the first type of heating elements ^, 26b and the second type of heating elements 32, and between the inlets (9) and (4), the valve 42-like temperature sensor 34 is connected to - control or adjustment (4) (such as 3, therefore, the first type of heating elements 26a, 26b and the second type of heating element 32' and the valves 43 and 42 at the inlet 29 and the outlet 3 can be controlled based on the reading of the temperature sensor and BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a conceptual diagram of a specific embodiment of the method and apparatus of the present invention.
