ABSTRACT:
An improved high-voltage device structure (10, 50, or 60) is a hybrid silicon-based
on-silicon-based power device that has a low R.sub.ds(on) relative to devices formed using only a silicon substrate and includes control circuit (14, 14' or 14") formed on silicon substrate region (12 or 62). High-voltage circuit (16, 16' or 16") is formed in non-silicon substrate region (18). Connecting circuitry (34 and 66) connects control circuit (14, 14', and 14") with high-voltage circuit (16, 16' or 16") to form high-voltage device structure (10, 50 or 60) that has improved control circuit performance and improved high-voltage circuits performance over devices formed solely from a silicon substrate or solely from a non-silicon substrate.
