Abstract:
1. A semiconductor structure comprising: a first field effect transistor including a top semiconductor portion, a first gate dielectric abutting said top semiconductor portion, a first gate electrode abutting said first gate dielectric; an insulator layer comprising a dielectric material and abutting said top semiconductor portion; a bottom semiconductor layer abutting said insulator layer; and a second field effect transistor including a second source region and a second drain region located in said bottom semiconductor layer, a second gate dielectric abutting said second source region and said second drain region and of integral construction with said insulator layer, and a second gate electrode comprising a same semiconductor material as said top semiconductor portion and abutting said second gate dielectric; and wherein said second gate dielectric and said insulator layer have a same thickness and a same composition.
