Abstract
A power metal-oxide-semiconductor field effect transistor (MOSFET)() incorporates a stepped drift region including a shallow trench insulator (STI)() partially overlapped by the gate () and which extends a portion of the distance to a drain region (). A silicide block extends from and partially overlaps STI () and drain region (). The STI () has a width that is approximately 50% to 75% of the drift region.
