Patent ID: 7229886

Claim:
A method of forming an integrated circuit, comprising: providing a semiconductor substrate; forming a switch on said semiconductor substrate; and forming a driver switch of a driver embodied in a transistor, including: forming a gate over said semiconductor substrate, forming a source/drain by: forming a lightly doped region adjacent a channel region recessed into said semiconductor substrate, and forming a heavily doped region of like type to and adjacent said lightly doped region, forming an oppositely doped well with respect to said lightly and heavily doped regions under and within said channel region, forming a doped region of like type to said heavily doped region and between said heavily doped region and said oppositely doped well, said doped region having a doping concentration profile less than a doping concentration profile of said heavily doped region, and forming an oppositely doped buried layer with respect to and under said doped region.
