The present invention provides, in one embodiment, a process for fabricating a metal oxide semiconductor (MOS) device (100). The process includes forming a gate (120) on a substrate (105) and forming a source/drain extension (160) in the substrate (105).

A method of forming a semiconductor device includes forming one or more sidewall spacer layers on the outer surface of a gate stack. At least one region of an at least partially formed semiconductor device is doped. First and second sidewall bodies are formed on opposing sides of the gate stack. The formation of the first and second sidewall bodies includes forming a first sidewall-forming layer on the outward surface of the gate stack and the sidewall spacer layers, exposing the semiconductor device to a heating cycle in a single wafer reactor, and forming a second sidewall-forming layer on the outward surface of the first sidewall-forming layer. The formation of the second sidewall-forming layer occurs in an environment that substantially minimizes dopant loss and deactivation in the at least one region of the partially formed semiconductor device.

摘要:
An improved source/drain extension process is provided by processing steps (steps A and G) that cover the wafer and dry etching steps (steps D and I) that provide side wall spacers of poly oxide and/or cap oxide from the PMOS gate areas before doing PMOS implanting steps(K and M). The capping of the wafer (step G)with the cap oxide after the NMOS implant also prevents the arsenic from out diffusing from the silicon. Further embodiments include implanting directly on the base.
