    摘要: Disclosed is a MOSFET including at least one transistor cell. The at least one transistor cell includes a source region, a drain region, a body region and a drift region. The body region is arranged between the source region and the drift region and the drift region is arranged between the body region and the drain region. The at least one transistor cell further includes a compensation region arranged in the drift region and distant to the body region, a source electrode electrically contacting the source region and the body region, a gate electrode arranged adjacent the body region and dielectrically insulated from the body region by a gate dielectric, and a coupling arrangement including a control terminal. The coupling arrangement is configured to electrically couple the compensation region to at least one of the body region, the source region, the source electrode and the gate electrode dependent on a control signal received at the control terminal.

    摘要: A power semiconductor element having a lightly doped drift and buffer layer is disclosed. One embodiment has, underneath and between deep well regions of a first conductivity type, a lightly doped drift and buffer layer of a second conductivity type. The drift and buffer layer has a minimum vertical extension between a drain contact layer on the adjacent surface of a semiconductor substrate and the bottom of the deepest well region which is at least equal to a minimum lateral distance between the deep well regions. The vertical extension can also be determined such that a total amount of dopant per unit area in the drift and buffer layer is larger than a breakdown charge amount at breakdown voltage.
