Abstract

See full text

A voltage-controlled switching device includes a drain/drift region of a first conductivity type formed in a semiconductor portion. A channel region and the drain/drift region are in direct contact with each other. A source region of a second conductivity type and the channel region are in direct contact with each other. A gate electrode and the channel region are capacitively coupled and configured such that, in a an on-state of the voltage-controlled switching device, a first enhancement region of charge carriers corresponding to the first conductivity type forms in the channel region and band-to-band tunneling is facilitated between the source region and the first enhancement region.
