Abstract:
A gate-controlled, BBT transit time diode device comprising:a substrate; a buried insulator layer overlying said substrate; a semiconductor layer overlying said buried insulator layer; an emitter region in said semiconductor layer wherein said emitter region extends down to said buried insulator layer; a barrier region in said semiconductor layer wherein said barrier region is in contact with said emitter region and is laterally adjacent to said emitter region and wherein said barrier region extends down to said buried insulator layer; a collector region in said semiconductor layer wherein said collector region extends down to said buried insulator layer; a drift region comprising said semiconductor layer between said barrier region and said collector region; and a gate comprising a conductor layer overlying said drift region, said barrier region, and at least a part of said emitter region with an insulator layer therebetween.
