Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a gate electrode over the semiconductor substrate, wherein the gate electrode has a gate width direction; a source region in the semiconductor substrate and adjacent the gate electrode, wherein the source region has a first width in a direction parallel to the gate width direction; a bulk pick-up region in the semiconductor substrate and abutting the source region, wherein the bulk pick-up region has a second conductivity type opposite to a first conductivity type of the source region, and wherein the bulk pick-up region has a second width in the gate width direction, and wherein the second width is substantially less than the first width; a drain region on an opposite side of the gate electrode than the source region; and an additional gate electrode over the semiconductor substrate, wherein the source region is between the gate electrode and the additional gate electrode, and wherein the gate electrode and the additional gate electrode are electrically connected; wherein the source region is in a first well region, and the drain region is in a second well region of an opposite conductivity type than the first well region.
