Abstract:
An embodiment integrated circuit device and a method of making the same. The embodiment integrated circuit includes a substrate supporting a source with a first doping type and a drain with a second doping type on opposing sides of a channel region in the substrate, and a pocket disposed in the channel region, the pocket having the second doping type and spaced apart from the drain between about 2 nm and about 15 nm. In an embodiment, the pocket has a depth of between about 1 nanometer to about 30 nanometers.
