Patent ID: 7649234

Claim:
A semiconductor device including a semiconductor substrate having a surface comprising: a doped epitaxial layer formed on the surface of the substrate; a gate electrode disposed overlying the doped epitaxial layer; a first impurity doped region disposed within the doped epitaxial layer and partially offset from the gate electrode on a first side of the gate electrode, and implanted using a first type of doping; a halo implant region disposed within the first impurity doped region and implanted using the first type of doping; a gate overlapped lightly doped drain region disposed within the doped epitaxial layer on a second side of the gate electrode, and implanted using a second type of doping, wherein the second side is opposite the first side, and the second type of doping is opposite the first type of doping; a source region formed in the halo implant region, wherein the halo implant region extends beyond the source region, at least partially under the gate electrode, and into a channel area between the source region and a drain region; and a drain region formed in the gate overlapped lightly doped drain region, wherein the gate overlapped lightly doped drain region extends beyond the drain region, at least partially under the gate electrode, and into the channel area, and wherein the halo implant region and the gate overlapped lightly doped drain region are separated from each other.
