Patent ID: 7244989

Claim:
A semiconductor component comprising: a lateral insulated gate bipolar transistor (IGBT) comprising: a semiconductor substrate having a first conductivity type; a buried semiconductor region having a second conductivity type and located above the semiconductor substrate; a first semiconductor region having the first conductivity type and located above the buried semiconductor region; a second semiconductor region having the first conductivity type and located above the first semiconductor region, the second semiconductor region being separated from the buried semiconductor region by the first semiconductor region; a third semiconductor region having the second conductivity type and located above the first semiconductor region, the third semiconductor region being separated from the buried semiconductor region by the first semiconductor region; an emitter having the first conductivity type and disposed in the second semiconductor region; and a collector having the first conductivity type and disposed in the third semiconductor region, the collector providing an increase in conductivity of the third semiconductor region as a result of an injection of holes into the third semiconductor region having the second conductivity type and creation of carrier overflow, wherein the third semiconductor region and the buried semiconductor region deplete the first semiconductor region in response to a reverse bias potential applied between the collector and the emitter and the increase in conductivity in the third semiconductor region provides low ON-state voltage.
