Abstract: Methods and structures for relieving stresses in stressed semiconductor liners. A stress liner that enhances performance of either an NFET or a PFET is deposited over a semiconductor to cover the NFET and PFET. A disposable layer is deposited to entirely cover the stress liner, NFET and PFET. This disposable layer is selectively recessed to expose only the single stress liner over a gate of the NFET or PFET that is not enhanced by such stress liner, and then this exposed liner is removed to expose a top of such gate. Remaining portions of the disposable layer are removed, thereby enhancing performance of either the NFET or PFET, while avoiding degradation of the NFET or PFET not enhanced by the stress liner. The single stress liner is a tensile stress liner for enhancing performance of the NFET, or it is a compressive stress liner for enhancing performance of the PFET.

Abstract: A semiconductor device which, in spite of the existence of a dummy active region, eliminates the need for a larger chip area and improves the surface flatness of the semiconductor substrate. In the process of manufacturing it, a thick gate insulating film for a high voltage MISFET is formed over an n-type buried layer as an active region and a resistance element IR of an internal circuit is formed over the gate insulating film. Since the thick gate insulating film lies between the n-type buried layer and the resistance element IR, the coupling capacitance produced between the substrate (n-type buried layer) and the resistance element IR is reduced.
