Abstract:
A method for forming a CMOS integrated circuit device, the method including; providing a semiconductor substrate, forming a gate layer overlying the semiconductor substrate, patterning the gate layer to form NMOS and PMOS gate structures including edges; forming a first dielectric layer overlying the NMOS and PMOS gate structures to protect the NMOS and PMOS gate structures including the edges, forming a first masking layer overlying a first region adjacent the NMOS gate structure; etching a first source region and a first drain region adjacent to the PMOS gate structure using the first masking layer as a protective layer for the first region adjacent the NMOS gate structure, and depositing a silicon germanium material into the first source and drain regions to cause the channel region between the first source and drain regions of the PMOS gate structure to be strained in a compressive mode.
