The Chang Group along with teams from UT Dallas (Prof. Julia Hsu, Prof. Kevin Brenner, Prof. Cormac Toher) and Johns Hopkins University (Prof. Howard Katz) have been co-awarded an NSF FuSe2 grant to develop indium based inorganic resists for extreme ultraviolet (EUV) lithography. The project aims to create innovative materials for next-generation semiconductor manufacturing, enabling smaller and more precise chip features. This research will contribute to advancing chip performance and energy efficiency, supporting the evolving demands of the semiconductor industry.
