Patent ID: 8836026

Claim:
A high-voltage transistor comprising: a substrate made of semiconductor material with an upper side, doped wells at the upper side, which comprise at least a first well provided for a drift section and a second well provided for a channel region; a first contact area for a drain terminal in the first well; a second contact area for a source terminal in the second well; a gate dielectric on a region of the second well between the first contact area and the second contact area, a gate electrode on the gate dielectric; and at least two additional dielectric regions, each of whose thicknesses is different from one another and from a thickness of the gate dielectric, the at least two additional dielectric regions being disposed on the upper side on the first well between the first contact area and the second contact area, wherein at least one of the at least two dielectric regions is a capacitor dielectric, and wherein an electrical conductor made of polysilicon and electroconductively connected to the gate electrode is arranged on the capacitor dielectric.
