Abstract
A semiconductor device includes a gate electrode disposed on a substrate. A source region and a drain region are disposed in the substrate and located on two sides of the gate electrode respectively. The drain region includes a plurality of drain segments that are laterally separated from each other. These drain segments have a first conductive type and the substrate has a second conductive type. A plurality of drain contacts is electrically connected to the drain segments. Each drain segment corresponds to at least one of these drain contacts. A drain electrode is electrically connected to these drain contacts. A source electrode is electrically connected to the source region.
