81 semiconductor engineer interview questions shared by candidates

1) Introduce yourself 2) Explain PhD work (didn’t allow to use slides and had to explain orally) 3) MOS CV chara for LF, HF, different temperature, substrate bias, replacing n+ poly gate with p+ poly, and when source drain terminals are added. 4) Short channel effects: What is DIBL, How to quantify it, How to reduce it 5) What is GIDL, What is the mechanism, How to reduce it (thicker oxide and wide bandgap drain). 6) A tank with two pipes A and B. A can fill it in 8 hours. B can empty it in 16 hours. When both are turned on, how long will it take to fill?

3-person panel, with two PhD Semiconductor / Photonics SME Consultants and MBA Principal Overall it seemed a too-easy experience…. I’ve been grilled more for lower stakes. Walked through my resume, via ppt highlights slides , reviewing my patents, projects, publications -and a little info on my community involvement and personal activities. Answered easy qs from SMEs. Asked them a few qs about their org. and their experiences working remotely on semiconductor manufacturing.
