Abstract:
A semiconductor device comprising:a semiconductor body having a surface; a lateral MOS transistor at the surface of the semiconductor body, the lateral MOS transistor comprising a comparatively weakly doped region of a first conductivity type adjoining the surface, a strongly doped source and drain zone of the opposed, second conductivity type, a weakly doped drain extension between the drain zone and a channel region which extends between the drain extension and the source zone, and a gate electrode situated above the channel region and electrically insulated therefrom;an electrically insulating layer over the surface of the semiconductor body and having contact windows above the source and drain zones, through which contact windows the source zone and the drain zone are connected to a metal source contact and a drain contact, respectively, the insulating layer having at least one contact window above the gate electrode, through which window the gate electrode is connected to a metal gate electrode contact, the contacts having the shape of parallel metal strips lying next to one another; anda further metal strip which extends over the electrically insulating layer between the gate electrode contact strip and the drain contact strip and which is locally connected to the source contact strip, forming a screen between the gate electrode strip and the drain contact strip.
