DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to directed writing, and more particularly to an apparatus, a system and a method comprising and utilizing a material carrier having a A programmable (four) layer of tracking material on the carrier. [Prior Art] Guide writing is a technique for creating a pattern on a substrate by adding or removing material from a substrate without using a mask or a pre-existing form. Guided write technology facilitates rapid prototyping of various electronic circuits. In the electronics industry, this has the advantage that directing writers is faster and more convenient than using mask-based materials such as photolithography. The prototype design can be repeated more quickly, resulting in a faster deployment of the end product. Typically, the minimum feature that can be written using the index write technique is on the order of a few microns. There are several guidelines for writing methods. See, for example, Laser Focus World, September 2, U.S. Patent No. 7, pp. 14,885, to D〇uglas et al. Calling (10) writing builds biostructures)". It would be advantageous to provide three-dimensional printing using an addressing and tracking scheme based on a disc format that deposits material on a substrate in a user defined order. SUMMARY OF THE INVENTION All illustrative embodiments will describe laser guidance writing, also referred to as laser induced forward transfer, in accordance with the principles of the present invention. In this example, a pulsed laser beam is directed through a transparent substrate and focused onto a film of material on the opposite side of the substrate. Preferably, the substrate does not absorb the laser light. The poly 136214.doc 200945339 energizes the laser pulse to vaporize the material in the film, which is then advanced to another adjacent substrate onto which the material is deposited. By depositing such suitable materials in a predefined order, the user can design, for example, an electronic circuit or a mesoscopic material. In a particularly useful embodiment, a layer between about 〇1 and about 1 〇 micron can be written. The most advanced laser write speed is within the range of ijm/s. The resolution is limited by the size of the laser focus point, which may be approximately _ 1 〇〇 micron. Combining these numbers yields a growth rate of 0.001-0,002 cm3/s (ie 3.6_ 7.2 cm3/h). These numbers can be compared to figures quoted in a commercial rapid prototyping two-dimensional (3D) laser printing system. A directing write carrier comprises a layer of material having at least one material deposited on the - face of the carrier. - The tracking layer is provided and (iv) is placed on the material layer. The tracking layer includes a readable medium for storing data that is used to provide information regarding the at least one material and the location of the at least one material on the carrier during indexing. 10—Guide the writer system and its methods include - configured to direct-write lasers - and an orbiting laser optical assembly. - Carrier has - material layer and a track: & The carrier is movable relative to the optical assembly such that when the material I is energized by the writing laser, the writer is directed to the surface below the carrier. The edge tracking layer contains readable material that is used to control one of the positions of the optical assembly and the carrier. Another guidance writer system includes an optical assembly configured to direct a write laser and a tracking laser via a homo-objective such that the tracking laser provides information to maintain the write Laser focusing. A disc consists of a material layer 136214.doc 200945339 material layer and a tracking layer. The layer of material comprises at least one material disposed in two dimensions such that the writing laser is controlled to selectively ablate the layer of material to deposit the ablated material on a surface. The tracking layer has a data track with readable material "This readable material is read during the index writing process to provide information regarding at least one material type, material location and ablation criteria. A method of directing writing includes reading data from a tracking layer formed on a carrier to determine a type and location of a material formed on a material layer formed on the carrier based on the data, and writing via focusing A laser ablates the layer of material through the tracking layer and positions the carrier according to the data to selectively ablate material to be deposited on a surface such that the index write is provided to a surface below the carrier . These and other objects, features and advantages of the present invention will become apparent from the Detailed Description of the Description of Description DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a directed writing technique that is provided to a three dimensional printed (functional) material on a substrate. This provides the user with a rapid prototyping technique in which the user can create Designing and printing the design immediately. A particularly useful embodiment is based on a material carrier. The material carrier can comprise a disc having a tracking layer and a material layer. A burn button laser is used to remove the layer from the material. The materials are deposited on a separate substrate. The separate substrate may comprise, for example, a board where the circuitry can be written directly for prototype design, etc. The tracking laser ensures that the correct material is deposited. A code (recorded or stylized information) on the disc describes the type and location of the material on the disc and how to "write" the material. A one or two dimensional format is provided on the carrier and the information stored on the carrier is tracked in accordance with the principles of the present invention.

In addition, a portion of the surface can be used to perform power measurements and laser focus (spot size, etc.) measurements to find the optimum laser ablation power. A lookup table can be used to provide information about the location and type of the materials on the surface. A wobble frequency can also be used to provide information about the location of the materials on the surface. This addressing scheme thus facilitates the use of different materials on the surface since the location of the materials is known. By utilizing the two-dimensional format, faster access times can be provided without the risk of tape breakage compared to the linear, one-dimensional case of tape. (One-dimensional systems can be written using tape guidance). These tapes are susceptible to breakage during writing to 11. In addition, optical discs are inexpensive to manufacture and contain inexpensive materials (e.g., a polycarbonate substrate). The embodiments described herein will illustratively focus on the use of laser moon packs! The guidelines are written into the technology. It should be understood that these index writing techniques can utilize a plurality of lasers of different beam sizes and wavelengths, and the spot size can be different based on these features, the lens used, the focal length, and other optical characteristics. Further, other methods that may benefit from such teachings in accordance with the present invention may be used to write. For example, 'other types of energy or radiation can be utilized and 136214.doc 200945339 directed to change the layers on the substrate to directly write or image the layers. For example, an arc can be utilized. It should also be understood that the illustrative examples described herein may be adapted to include additional electronic components. These elements may be integrally formed with the laser device or provided as a separate device. For example, a tracking or positioning device can be included with the laser device in a single assembly. The elements depicted in the attached circle can be implemented in different combinations of hardware and software and provide the functionality that can be combined in a single element or multiple elements.

The deposition material 17 is deposited on the substrate 24 because of the burnt name (or other directing writing process). The materials 15 on the material layer 18 can be constructed in a spiral shape, a circle, a radial surface, or the like. (See, for example, Figures 3A through 3D). The tracking layer 14 and the material layer 18 are spatially separated such that the tracking layer 14 is not damaged by the focused firing button (4). The routing layer 14 is preferably transparent to the ablation or writing laser 16. X An addressing method for such materials on the optical disc 12 can mimic the addressing method utilized in other optical disc formats, or the addressing method can simply include information indicating that the material is present at a given location. In one embodiment, the addressing scheme provides a means of addressing a plurality of materials on a single optical disc, for example, information stored in the tracking layer 14 can provide information about the type of material in the layer of material, available Information about the position of a given type of material and any information for setting the laser, controlling ablation, controlling the rotational speed of the disc, or other auxiliary guidance writing process. In one embodiment A preamble of a type of ADIP can be provided on the optical disc 12 (e.g., in the tracking layer 14) that provides information about what material is on the 136214.doc • 11 · 200945339 disc 12, from which the disc is burned. The information on the strength of the material required for these surnames' and the provision of a power calibration magnetic zone to make the burnt-button laser suitable for custom materials or variations. A portion of the preamble on the disc can be writable or rewritable. The writable portion can be used to store information as to which portion of the disc 12 has been accessed and where the material has been burned. This addressing scheme is also applicable to tape-based systems. The index writing system 10 of Fig. 1 is shown in more detail with reference to Fig. 2' in accordance with an illustrative embodiment. The optical assembly 11 is shown in more detail. Material 46 is ablated from the disc 12 as a carrier for the materials. Using a powerful pulse-transferred laser or burnt-out laser 16, different materials 46 are burned from the disc 12 onto the substrate 24, which is mounted on an xyz translation stage 4''. Additionally, a pulsed laser 32 can be used to anneal the deposited material 42. A tracking laser (22) controlled by a tracking and imaging module 44 and the servo system maintain the ablation beam 16 on the target. The tracking and imaging module 44 can include a tracking laser for reading the reflection and can include an imaging camera to provide instant feedback of the deposition process. In one embodiment, a matrix assisted pulsed laser evaporation (guided write (MAPLE-DW) mounting) is utilized. As described above, the carrier used in the prior art is a tape or a magnetic tape. In accordance with the principles of the present invention, a one- or two-dimensional carrier is utilized with tracking information about the carrier that aids in the identification and processing of materials on the carrier. In an embodiment, the carrier comprises a compact disc. Preferably, the disc 12 includes concave rails that facilitate the storage of laser tracking and process information. The disc 12 provides a surface to which material 46 in the material layer 18 can be attached. These materials are then ablated or vapor deposited and deposited on substrate 24 by 136214.doc 200945339. A pulsed high power laser 16 is focused on an interface between the disc substrate 14 and the material layer 18. The material 46 present at the laser focus is ablated from the disc and advanced toward the substrate 24 mounted on the xyz bracket 4''. While other gap sizes are contemplated, the distance between the substrate 24 and the material layer 18 may be approximately 1 millimeter. Tracking is done in a similar manner to optical data storage. The circulatory laser 22 provides a radial push-pull signal, a signal to the push-pull signal and a focus error signal to the vocabulary system of the No. 3 rattan feedback module 44, so that the burnt laser 16 is always Focusing on the layer 18 of material. The ablation laser 16 and the tracking laser 22 are preferably focused onto the optical disk 12 via the same lens 38. The laser reflected from the optical disk 12 is read in the tracking and imaging module 44 to provide feedback for directing the writing process. Alternatively, an optical pickup unit (〇pu) may be provided for reading the optical disc 12. The circumscribing process includes information gathered about the location of the material 46 on the optical disk 12 and the location of the material 42 on the substrate 24. The tracking and imaging module 44 can include a computer device that can store the information and compare the information with a stored computer-aided design of the device to be manufactured in such a manner that the precise quality of the design can be Maintain and check to ensure that the specifications of the instructions are written to the circuit (or other object). A single lens system 38 is preferred so that the ablation beam 16 will automatically follow the tracking beam 22. Starting from the collimated beam, the ablation beam 16 is focused further downstream than the focus of the s-beam beam 22. This object is achieved with the same lens 38, using a wavelength (λι) of the burn button laser 16 that is longer than a wavelength (λ〇) of the circulatory laser 22. In one embodiment, an infrared ray The shot is used for ablation because it makes ablation of biological materials and tissue engineering possible. 136214.doc -13- 200945339 If the convergence is insufficient, a telescope 36 in the optical path of the tracking laser 22 can be used to create a converging incident tracking beam. A dichroic mirror 48 can be formed on the optical disc 12, the dichroic mirror "reflecting the light of the tracking laser 22" while transmitting the light of the ablation laser 16. The ablated laser beam 16 is The intensity of the position of the tracking layer 14 should be lower than the damage threshold of the tracking layer 14. This limits the focus of the lens 38 to focus the ablated laser beam 16. The tracking layer 14 and the material layer The distance between 18 can be made as large as needed to prevent damage due to the use of the telescope in the optical path of the tracking laser 22. Once the material 46 is ablated, the material is deposited. 42 is on the substrate 24. The annealing laser 32 is then used to anneal or otherwise treat the deposition material 42. The deposition material 42 may comprise a -helix pattern which may be selected from the material_burning The material optionally comprises different materials. Because multiple lasers and optical devices are utilized, the dichroic mirror 34 can be used to redirect and beam the light as needed. In addition, other optical splits, including lenses, Filter, light mirror, beam splitter, mirror or other device, depending on The application and the configuration can be utilized. Referring to Figures 3A through 3D, a plurality of different disc layouts are illustratively depicted. Material 46 is deposited in the web 52 on the disc 12. Tracking is done at - a spiral groove or track 54 (Fig. 3A) or on a concentric groove % (Fig. 3b). The layer of mixed material may comprise material in the radial layout 58 and material along a track 60 (Fig. 3C) And the material (10) (Fig. 3D) laid out along the outside of the track 56. These tracks may be concentric or spiral. The tracking layer (18) has a spiral track or a concentric track n layer _ I36214. Doc •14· 200945339 contains spokes (52, 58) with different materials 46. In other words, each spoke is a different material or combination of materials. These materials 46, as shown in Figures 3D and 3C 56 and 6〇' can also be along these tracks 54, riding and mixing of material surfaces with material tracks (figure and 3D). For pulsed rice cooking applications, only a light-surface layout It is preferred that the advantages of the lightweight layout include that different materials can be deposited without moving the sample relative to the center of rotation of the disc. The pulse nature of the burned worm, the rotation of the disc must be synchronized with the repetition rate of the burn (four) shot. The material is strobed to burn the button. The rotation of the light can be stopped and the radial direction or tangentially in the jurisdiction Intra-area scanning. Radial or tangential tracking is less important. φ When a continuous wave laser provides sufficient power to ablate the material from the disc, the layout is better; however, in practice, with a pulsed thunder The ablation system is easier to achieve ablation. These discs can be made by depositing material on a layer of beta material using a simple "radial" mask. The webs 52 are preferably sufficiently separated to prevent such light sidelines from being contaminated. The tracking layer 14 provides information about the location of the system on the optical disc 2... an Amp-like preamble can be provided on the optical disc to provide information about what material is on the optical disc, providing information from the optical disc The strength required for these materials, as well as the provision of a -power calibration magnetic zone to make the ablation laser suitable for custom materials or variations. In a further preferred embodiment, a portion of the preamble on the disc is writable (rewritable). The writable portion is used to store information about which portion of the disc has been accessed and where the material has been burned. A standard optical disc (CD, DVD) has a surface area of about H) 0 square centimeters (more specifically, 88 square meters). Suppose we can burn silver / write a 1 〇 micron 136214.doc 15 200945339 material layer, then - the disc can hold about o.i cubic centimeter of material. Larger discs, such as laser discs, can of course accommodate more material, reducing the number of discs needed to print an object. Embodiments of the invention may be implemented in a number of different applications. These applications may include, for example, rapid prototyping of electronic circuits, biomanufacturing, tissue engineering, applied decorative design, and the like. With a fast, original design that is closer to the end user, the end user can design a circuit (electronic device) using a computer-aided design program and then print a fully functional 3D design. The flowchart of Figure 4 illustratively depicts a method of writing in accordance with the guidelines of the present invention. In block 1-2, a carrier is provided with a layer of material and a tracking layer contained in - or two dimensions. The layer of material comprises one or more materials formed by a radial spiral or other shape. The tracking layer can comprise a polycarbonate material (e.g., a disc) having a magnetic track formed therein. The track may contain data written in a spiral or concentric circle t. The tracking layer can include a dichroic mirror, and in block 104, the tracking laser can be reflected from the dichroic mirror and used to track the writing laser. The write laser is transmitted through the tracking layer. The tracking laser is focused with the writer's laser through the same objective lens. In block 108, the material is read from a tracking layer (e.g., via use: a tracking laser or using - optical pickup of a single stick PU)). The data is extracted on the carrier to determine the type and location of a material in the layer of material formed on the carrier. Other information can also be stored in the tracking layer. In block 110, based on the data, the material of the layer of material is burned through the tracking layer via a focus-write laser. The write laser needs to have sufficient power. I362l4.doc -16 - 200945339 Burn #The materials provided in the material layer. In block 112, the carrier is positioned and repositioned to selectively ablate material deposited on a surface based on the material such that the index writing is provided to a surface below or below the carrier. In block 114, the deposited material formed on the surface can be annealed in block 116 using an annealed-laser that can be imaged to provide feedback and control deposition for directing writes. In addition, feedback is provided to blocks 110 and 112 and used to reposition the carrier, adjusting laser power and other characteristics. In block 118, the substrate is translated to direct writing a pattern on the substrate.
