Re: error using SiO2 as dielectric material in mosfet

You could post your file and see if anyone else could help. If you had a simulation that worked ok, you should go back to that one and change that one with what you want to do. To me it seems like you are missing something in your material definition. W/o seeing the file I would be guessing. If this is being done in the semiconductor module, I am of very little help because I do not have it. Perhaps screen shots would work ok. Do you get any red flags in the materials section?
