Abstract

A semiconductor device, such as a laterally diffused metal-oxide-semiconductor (LDMOS) transistor, includes a semiconductor substrate in which a source region and a drain region are disposed. The drain region has a drain finger terminating at a drain end. A gate structure is supported by the semiconductor substrate between the source region and the drain region, the gate structure extending laterally beyond the drain end. A drift region in the semiconductor substrate extends laterally from the drain region to at least the gate structure. The drift region is characterized by a first distance between a first sidewall of the drain finger and a second sidewall of the gate structure, and the gate structure is laterally tilted away from the drain region at the drain end of the drain finger to a second distance that is greater than the first distance.
