Claim Text:
1. A field-effect transistor (FET) comprising: a well of a first type dopant, formed in a semiconductor substrate; a metal gate disposed on the semiconductor substrate and overlying the well; a channel formed in the semiconductor substrate and underlying the metal gate; a lightly doped source region and a lightly doped drain region of a second type dopant opposite from the first type, the lightly doped source region and the lightly doped drain region being formed in the semiconductor substrate and on opposite sides of the channel; and a pocket doping profile of the first type dopant defined in the well to form a pocket implant region directly interfacing with the lightly doped source region and the lightly doped drain region, wherein the pocket implant region has a uniform doping concentration extending continuously from the lightly doped source region to the lightly doped drain region.
