Patent number: 9202688Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.Type: GrantFiled: June 20, 2014Date of Patent: December 1, 2015Assignee: PIXELLIGENT TECHNOLOGIES, LLCInventors: Zehra Serpil Gonen Williams, Yijun Wang, Robert J.

Patent number: 9048009Abstract: Domain segregation of polymer blends or block copolymers in the presence of thermal conducting high aspect ratio nanocrystals leads to preferential placement of conductive filler either inside one domain, which promote the self-assembly of a thermal and/or electrical conducting pathway composed of high aspect ratio filler. The self-assembly of such thermal and/or electrical conducting pathway effectively enhances the thermal and/or electrical conductivity of the composite with significantly less amount of filler.Type: GrantFiled: November 21, 2012Date of Patent: June 2, 2015Assignee: PIXELLIGENT TECHNOLOGIES, LLCInventors: Wei Xu, Jun Xu, Zehra Serpil Gonen-Williams, Gregory D.

Patent number: 8993221Abstract: An integrated circuit is made by depositing a pinning layer on a substrate. A block copolymer photoresist is formed on the pinning layer. The block copolymer has two blocks A and B that do not self-assemble under at least some annealing conditions. The exposed block copolymer photoresist is processed to cleave at least some block copolymer bonds in the exposed selected regions. The exposed pinning layer is processed to create a chemical epitaxial pattern to direct the local self assembly of the block copolymer.Type: GrantFiled: February 11, 2013Date of Patent: March 31, 2015Assignee: Pixelligent Technologies, LLCInventors: Gregory D.

Patent number: 7649615Abstract: Advanced techniques for programmable photolithography provide enhanced resolution and can image features smaller than the single shutter intensity profile, i.e., sub-pixel resolution. Patterns are built up by multiple exposures with relative movement of the mask and resist so as to place each shape from the library where it is needed on the resist. Electro-Optic phase shifting material may be applied to the shutter so as to adjust the single shutter intensity profile, or to adjust the interaction of adjacent shutters. An apodizing mask may be used to engineer the wavefronts of the light striking the resist to achieve better resolution.Type: GrantFiled: May 2, 2007Date of Patent: January 19, 2010Assignee: Pixelligent Technologies LLCInventors: Andrew Case, Gregory D.
