Abstract:
A lateral transistor comprising:a semiconductor substrate of a first conductivity type having a major surface;an emitter region of a second conductivity type in said semiconductor substrate on the major surface of said semiconductor substrate;a collector region of a second conductivity type in said semiconductor substrate on the major surface of said semiconductor substrate, spaced from and surrounding said emitter region, and including a plurality of sides and corners;an electrically insulating layer on the major surface of said semiconductor substrate and including a first penetrating hole extending to said collector region except at a first corner of said plurality of corners and a second penetrating hole extending to said emitter region;a collector electrode contacting said collector region through said first penetrating hole and surrounding said emitter region except at said first corner;an emitter electrode at the same level as said collector electrode and contacting said emitter region through said second penetrating hole; andan emitter wiring layer at the same level as said emitter electrode, disposed on said insulating layer, and extending from said emitter electrode across said first corner.
