Patent ID: 8803250

Claim:
A Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET), comprising: a substrate; a well region formed in the substrate; a shallow channel layer formed on a portion of the well region and including a first shallow channel region and a second shallow channel region; a channel arranged between the first shallow channel region and the second shallow channel region and connecting the first shallow channel region and the second shallow channel region; a gate oxide layer formed on a portion of the well region between the first shallow channel region and the second shallow channel region and including a first gate oxide region and a second gate oxide region arranged on different sides of the channel; a gate region formed on the channel and the gate oxide layer; a source region formed in the first shallow channel region and vertically extending into the well region under the first shallow channel region; and a drain region formed in the second shallow channel region and vertically extending into the well region under the second shallow channel region.
