Classification: CPC H | IPC H

Claim 8:
9. A semiconductor device, comprising:
a substrate having a top surface, comprising:
a first drift region with a first conductivity type, extending from the top surface of the substrate into the substrate;
a second drift region with the first conductivity type, extending from the top surface of the substrate into the substrate and located adjacent to the first drift region; and
a drain region of the first conductive type within the first drift region;

a field plate over the substrate;
a gate electrode having a first portion and a second portion, wherein the first portion of the gate electrode is located over the field plate; and
a silicide layer on the gate electrode, and an upper surface of the gate electrode is entirely in contact with the silicide layer.
