Abstract
A semiconductor device including drain extended metal oxide semiconductor field effect transistor (MOSFET) includes a source region and a drain region each having a first dopant type spaced apart along a surface of a semiconductor material having a second opposite conductivity type. A gate electrode over the semiconductor material surface between the source region and the drain region. A diffusion suppression implant region in the semiconductor material extends from the source region under the gate electrode. The diffusion suppression implant region includes a body region having the second opposite conductivity type and comprises at least one of carbon, nitrogen, and fluorine.
