I was first asked with several general questions such as the difference of live between my home country and the US. Then, he started to ask me about some technical questions which he called as a technical discussion. The questions included some basic concepts of semiconductor physis, methods of characterization, and which course I took so far is the most interesting and why. Explain the purpose of lithography and the physics of CMOS. What is the goal of high k materials on CMOS?
