Abstract:
A lateral insulated gate bipolar transistor (IGBT) in a silicon on insulator (SOI) configuration having a top side and an underside, comprising:a drain zone of a first conductivity type extending to the top side;an anode zone of a second conductivity type incorporated in said drain zone and extending to the top side;a base zone of the second conductivity type incorporated in said drain zone and extending to the top side;a source zone of the first conductivity type incorporated in said base zone and extending to the top side;a substrate of the second conductivity type forming the underside;a source electrode disposed in contact with said source zone and said base zone;a drain electrode disposed in contact with said anode zone;a gate insulating layer disposed on the top side between said source zone and said anode zone;a gate electrode disposed on said gate insulating layer;a lateral insulation layer disposed between said drain zone and said substrate; andat least one laterally formed region of the second conductivity type disposed in said drain zone in a vicinity of said lateral insulation layer.
