SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

A semiconductor device includes: an active region defined by a device isolation layer on and/or over a substrate; a second conductive well on and/or over the active region; an extended drain formed at one side of the second conductive well; a gate electrode on and/or over the second conductive well and the extended drain; and a source and a drain formed at both sides of the gate electrode, in which extended regions are formed at the corners of the second conductive well under the gate electrode.
