WebJan 23, 2013 · A field oxide NMOSFET would'nt work in this circuit configuration (would always be off). BTW: A field oxide thickness of 1.38µm would be that of a very old process: a process size of 1.5 or 2µm had used such a thick field oxide, and such processes we had around 15..20 years ago. WebIn microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a wafer.The technique forces an oxidizing agent to diffuse into the wafer at high temperature and react with it. The rate of oxide growth is often predicted by the Deal–Grove model. Thermal oxidation may be applied to different …
