Abstract

A semiconductor structure has embedded stressor material for enhanced transistor performance. The method of forming the semiconductor structure includes etching an undercut in a substrate material under one or more gate structures while protecting an implant with a liner material. The method further includes removing the liner material on a side of the implant and depositing stressor material in the undercut under the one or more gate structures.
