Abstract
A method for forming a semiconductor device is disclosed. A p-type field-effect transistor (p-FET) is formed on a semiconductor substrate. A dielectric layer is formed on the semiconductor substrate and completely covers the p-FET. At least an opening is formed in the dielectric layer and exposes a source/drain region of the p-FET. A conductive material is then formed filling the opening, wherein the conductive material comprises a first stress; specifically, a tensile stress between 400 and 800 MPa.
