Abstract

Recessed Si<subscript>0.8</subscript>Ge<subscript>0.2</subscript> source/drain (S/D) and a compressive contact etch-stop layer have been successfully integrated resulting in nearly 200% improvement in hole mobility. This is the largest reported process-induced hole mobility enhancement to the authors' knowledge. This letter demonstrates that a drive-current improvement from recessed Si<subscript>0.8</subscript>Ge<subscript>0.2</subscript> plus the compressive nitride layer are in fact additive. Furthermore, it shows that the mobility enhancement is a superlinear function of stress, leading to larger than additive gains in the drive current when combining several stress sources.
