Publication number: 20150185616Abstract: New routes involving multi-step reversible photo-chemical reactions using two-step techniques to provide non-linear resist for lithography are described in this disclosure. They may provide exposure quadratically dependant on the intensity of the light. Several specific examples, including but not limited to using nanocrystals, are also described. Combined with double patterning, these approaches may create sub-diffraction limit feature density.Type: ApplicationFiled: January 7, 2015Publication date: July 2, 2015Inventors: Gregory D. COOPER, Zhiyun CHEN, Z. Serpil GONEN WILLIAMS, Larry F. THOMPSON

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: 8920675Abstract: 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: October 26, 2011Date of Patent: December 30, 2014Assignee: Pixelligent Technologies, LLCInventors: Wei Xu, Zehra Serpil Gonen Williams, Yijun Wang, Robert J. Wiacek, Xia Bai, Linfeng Gou, Selina I. Thomas, Jun Xu
