Shin-jae You is an Associate Professor in the Department of Physics at Chungnam National University. Dr. You received his B.S. in Physics from Chungnam National University (1999) and his Ph.D. in Physics from Korea Advanced Institute of Science and Technology (2005). Prior to his appointments at Chungnam National University, Dr. You was a Postdoctoral Fellow at Korea Advanced Institute of Science and Technology (2005-6) and at Pohang University of Science and Tech (2006-7) and a Senior Research Scientist at Korea Research Institute of Standards and Science (KRISS) (2007-2014). Dr. You is a member of the Steering Committee in the Korea Vacuum Society (2010). He has also received the Bronze Prize in Samsung Human Tech Thesis Prizes (2005) and the KRISS AWARD (2013), and has been published in Marquis Who's Who in the world 2009 for the expert on the plasma electron kinetics. Dr. You’s research interests are in the areas of electron kinetics in low/high pressure plasma, plasma diagnostics, plasma simulation, plasma source development, plasma parameter control, plasma fault detection and classification, plasma levitation and nano particle synthesis, and ultra low-pressure low-density plasma source and its application. He is currently directing a research effort focusing on the development of plasma technology in atomic layer etching (ALE) and high-aspect-ratio contact (HARC) hole etching.
