Abstract:
A semiconductor device of a silicon-on-insulator structure which includes a semiconductor support substrate, a first insulating layer formed on said semiconductor support substrate, and a semiconductor layer formed on said first insulating layer, the semiconductor device comprising a conductive layer filled in a first hole penetrating through said semiconductor layer and said first insulating layer, said conductive layer being electrically connected to said semiconductor support substrate, a second insulating layer formed on said semiconductor layer, and a semiconductor support substrate potential fixing electrode formed on said second insulating layer and filled into a second hole penetrating through said second insulating layer in alignment with said first hole so that the portion of said semiconductor support substrate potential fixing electrode that is filled in said second hole extends only through said second insulating layer, said semiconductor support substrate potential fixing electrode being electrically connected through said conductive layer to said semiconductor support substrate.
