Dr. Sungyoung Yoon | Samsung Electronics | South Korea
Dr. Sungyoung Yoon is a distinguished plasma engineer specializing in the development of advanced plasma devices for semiconductor manufacturing. He currently serves as a Principal Engineer at Samsung Electronics, where he leads innovations in remote plasma sources (RPS), PECVD plasma uniformity control, and selective etching processes for next-generation V-NAND and 3D memory devices. He earned his Ph.D. in Nuclear Engineering with a focus on plasma physics and engineering from Seoul National University, where his research explored hydroxyl radical generation mechanisms in electrolyte streamer discharges. His academic foundation and technical expertise have driven a prolific career bridging plasma diagnostics, numerical modeling, and applied plasma engineering. Before joining Samsung, Dr. Yoon worked as a Senior Researcher at the Korea Institute of Fusion Energy (KFE) and as a Postdoctoral Associate at Seoul National University, where he contributed to projects involving plasma chemistry, optical diagnostics, and radical generation for industrial and biomedical applications. Dr. Yoon has authored SCI-indexed publications in leading journals such as Plasma Sources Science and Technology, Scientific Reports, and Physical Review Plasmas, and holds over a dozen international patents across Korea, the U.S., Taiwan, and China. His recent research explores metamaterials for plasma control, phase-controlled etching, and dual-frequency plasma systems.
