A semiconductor device includes at least one cell including a base region of a first conductivity type having disposed therein at least one emitter region of a second conductivity type, a first well region of a second conductivity type, a second well region of a first conductivity type, a drift region of a second conductivity type, a collector region of a first conductivity type, and a collector contact. Each cell is disposed within the first well region, and the first well region is disposed within the second well region. The device further includes a first gate in communication with a base region so that a MOSFET channel can be formed between an emitter region and the first well region, and at least one embedded region embedded in the first well region. The device is configured such that during operation of the device a depletion region at a junction between the base region and the first well region can extend to a junction between the first well region and the second well region.
