  • Publication number: 20240130210
    Abstract: An organic light-emitting diode (OLED) deposition system includes two deposition chambers, a transfer chamber between the two deposition chambers, a metrology system having one or more sensors to perform measurements of the workpiece within the transfer chamber, and a control system to cause the system to form an organic light-emitting diode layer stack on the workpiece. Vacuum is maintained around the workpiece while the workpiece is transferred between the two deposition chambers and while retaining the workpiece within the transfer chamber. The control system is configured to cause the two deposition chambers to deposit two layers of organic material onto the workpiece, and to receive a first plurality of measurements of the workpiece in the transfer chamber from the metrology system.

  • Publication number: 20220057710
    Abstract: Methods and apparatus for stamp generation are disclosed using nano-resist and ultra violet blocking materials. In one non-limiting embodiment, a method of producing a copy of a stamp for generating electrical/optical components is disclosed comprising: providing the stamp; coating a bottom surface of the stamp with a ultra violet blocking material; curing the ultra violet blocking material on the bottom surface; contacting the stamp to a target substrate covered with a layer of imprint resist; curing the imprint resist with ultraviolet blocking material during the contacting of the stamp to the target substrate; and releasing the stamp from the target substrate with the cured layer of imprint resist.

  • Publication number: 20200393599
    Abstract: An imaging system and a method of manufacturing a metalens array is provided. The imaging system includes a metalens array, and light scattered from an object is split by the metalens array, such that an image is formed in front of an observer. The metalens array is at least partially transparent to visible light, so that the observer can also see the environment. The method of manufacturing the metalens array includes bonding together a plurality of substrates, and dicing the plurality of substrates into metalens arrays. The metalens arrays can be used in the imaging system.

  • Patent number: 9780250
    Abstract: An improved method of doping a workpiece is disclosed. The method is particularly beneficial to the creation of interdigitated back contact (IBC) solar cells. A patterned implant is performed on one surface of the workpiece. A self-aligned masking process is then performed, which is achieved by exploiting the changes in surface properties caused by the patterned implant. The masking process includes applying a coating that preferentially adheres to the previously implanted regions. A blanket implant is then performed, which serves to implant the portions of the workpiece that are not covered by the coating. Thus, the blanket implant is actually a complementary implant, doping the regions that were not implanted by the first patterned implant. The coating is then optionally removed from the workpiece.

  • Patent number: 8747942
    Abstract: Solar cells are provided with carbon nanotubes (CNTs) which are used: to define a micron/sub-micron geometry of the solar cells; and/or as charge transporters for efficiently removing charge carriers from the absorber layer to reduce the rate of electron-hole recombination in the absorber layer. A solar cell may comprise: a substrate; a multiplicity of areas of metal catalyst on the surface of the substrate; a multiplicity of carbon nanotube bundles formed on the multiplicity of areas of metal catalyst, each bundle including carbon nanotubes aligned roughly perpendicular to the surface of the substrate; and a photoactive solar cell layer formed over the carbon nanotube bundles and exposed surfaces of the substrate, wherein the photoactive solar cell layer is continuous over the carbon nanotube bundles and the exposed surfaces of the substrate.
