Abstract:
A method for fabricating a FET transistor for an integrated circuit by the steps of forming recesses in a substrate on both sides of a gate on the substrate, halo/extension ion implanting into the recesses, and filling the recesses with embedded strained layers comprising dopants for in-situ doping of the source and drain of the transistor. The stress/strain relaxation of the resulting transistor is reduced.
