HIGH VOLTAGE SEMICONDUCTOR DEVICES AND METHODS FOR FABRICATING THE SAME

摘要

An exemplary embodiment of a semiconductor device capable of high-voltage operation includes a substrate with a well region therein. A gate stack with a first side and a second side opposite thereto, overlies the well region. Within the well region, a doped body region includes a channel region extending under a portion of the gate stack and a drift region is adjacent to the channel region. A drain region is within the drift region and spaced apart by a distance from the first side thereof and a source region is within the doped body region near the second side thereof. There is no P-N junction between the doped body region and the well region.
