Implant damage control by in-situ C doping during SiGe epitaxy for device applications

摘要

Some example embodiments of the invention comprise methods for and semiconductor structures comprised of: a MOS transistor comprised of source/drain regions, a gate dielectric, a gate electrode, channel region; a carbon doped SiGe region that applies a stress on the channel region whereby the carbon doped SiGe region retains stress/strain on the channel region after subsequent heat processing.
