Patent ID: 7977714

Claim:
A semiconductor structure comprising: at least one semiconductor channel having a first conductivity type doping and located in a semiconductor substrate; a gate electrode containing: a side gate region laterally abutting said at least one semiconductor channel and having a second conductivity type doping, wherein said second conductivity type is the opposite of said first conductivity type; a top gate region vertically abutting said at least one semiconductor channel and having said second conductivity type doping; and at least one bottom gate region vertically abutting said at least one semiconductor channel and having said second conductivity type doping; a shallow trench isolation structure including a dielectric material and laterally surrounding said top gate region; a buried doped layer vertically abutting said at least one bottom gate region and having a doping of said first conductivity type; and a substrate layer located in said semiconductor substrate, vertically abutting said buried doped layer and having a doping of said second conductivity type.
