    摘要: A semiconductor arrangement includes a MOSFET having a source region, a drift region and a drain region of a first conductivity type, a body region of a second conductivity type arranged between the source region and the drift region, a gate electrode arranged adjacent the body region and dielectrically insulated from the body region by a gate dielectric, and a source electrode contacting the source region and the body region. The semiconductor arrangement further includes a normally-off JFET having a channel region of the first conductivity type that is coupled between the source electrode and the drift region and extends adjacent the body region so that a p-n junction is formed between the body region and the channel region.
