Patent number: 12272607Abstract: The enclosed disclosure relates to a method and apparatus for depositing functionalized nanoparticles within a semiconductor structure in order to create a nano-layer capable of enhancing imaging and contrast, The semiconductor structure can include any type of VNAND structure or 3D structure, The nanoparticles are formed in high-aspect ratio trenches of the structure and form a nano-layer. The functionalized nanoparticles comprise synthesized nanoparticles as well as organic molecules. The organic molecules are chosen to selectively bind to certain nanoparticles and surface materials.Type: GrantFiled: December 8, 2020Date of Patent: April 8, 2025Assignee: Applied Materials, Inc.Inventors: Geetika Bajaj, Prerna Sonthalia Goradia, Robert J. Visser

Patent number: 12050327Abstract: 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.Type: GrantFiled: August 9, 2019Date of Patent: July 30, 2024Assignee: Applied Materials, Inc.Inventors: Jinxin Fu, Tapashree Roy, Ludovic Godet, Wayne McMillan, Robert J Visser

Patent number: 9780250Abstract: 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.Type: GrantFiled: January 14, 2016Date of Patent: October 3, 2017Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Vikram M. Bhosle, Timothy J. Miller, Tapash Chakraborty, Prerna Goradia, Robert J. Visser

Patent number: 8747942Abstract: 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.Type: GrantFiled: June 9, 2010Date of Patent: June 10, 2014Assignee: Applied Materials, Inc.Inventors: Omkaram Nalamasu, Charles Gay, Victor L. Pushparaj, Kaushal K. Singh, Robert J. Visser, Majeed A. Foad, Ralf Hofmann
