Dr. Chang-Yong Nam is a Senior Scientist (Research Staff 6) and the Leader of the Electronic Nanomaterials Group at the Center for Functional Nanomaterials (CFN) at Brookhaven National Laboratory (BNL). He is also an Adjunct Professor of Materials Science and Chemical Engineering at Stony Brook University, where he teaches a graduate course and advises graduate and undergraduate students. His research is focused on semiconductor materials processing, novel electronic devices & physics, and advanced patterning for next-generation microelectronics. Key areas include atomic layer processing (ALP)—including atomic layer deposition (ALD) and atomic layer etching (ALE)—as well as neuromorphic and low-dimensional materials and devices, and novel resist materials for extreme ultraviolet (EUV) lithography and beyond. He currently serves as the lead PI of the DOE Accelerate Initiative Award, "Angstrom Era Semiconductor Patterning Material Development Accelerator", an $8M project aimed at accelerating the development of next-generation EUV photoresists through vapor-phase materials synthesis and machine learning-driven correlation of proxy variables with ultimate EUV patterning performance.
