Abstract:
1. A semiconductor device comprising: a substrate having a first surface and a second surface; a first source region of a first conductivity type and a first body region of a second conductivity type formed in the substrate proximal to the first surface, the first source region formed in the first body region; a second source region of the first conductivity type and a second body region of the second conductivity type formed in the substrate proximal to the first surface, the second source region formed in the second body region; a drain region of the first conductivity type formed in the substrate proximal to the second surface; an epitaxial region of the first conductivity type formed in the substrate configured to function as a drift region between the drain region and the first and the second source regions; a dual-gate formed over the first surface and including a first gate proximal to the first body region and a second gate proximal to the second body region, the first gate and the second gate defining a gap there between, the first gate discrete from the second gate; and at least one drain side spacer disposed in the gap.
