Patent ID: 8319283

Claim:
A laterally diffused metal oxide semiconductor (LDMOS) device, comprising: a semiconductor substrate including a n-type drift region; a first gate over the semiconductor substrate and the n-type drift region, wherein the first gate is a control electrode; a second gate over the semiconductor substrate and the n-type drift region and laterally adjacent the first gate; a first doped region between and adjacent to the first gate and the second gate and that extends into the n-type drift region, wherein the first doped region is a p-doped region that shields edges of the first and second gates from high electric fields; a source region within the semiconductor substrate; and a drain region within the semiconductor substrate, wherein: the first gate, the second gate, and the first doped region are between the source region and the drain region; and the first doped region is doped less than the source region or the drain region, and wherein the first doped region acts as a voltage divider to distribute drain voltage in the semiconductor substrate during an off-state.
