    摘要: Compressive or tensile materials are selectively introduced beneath and in alignment with spacer areas and adjacent to channel areas of a semiconductor substrate to enhance or degrade electron and hole mobility in CMOS circuits. A process entails steps of creating dummy spacers, forming a dielectric mandrel (i.e., mask), removing the dummy spacers, etching recesses into the underlying semiconductor substrate, introducing a compressive or tensile material into a portion of each recess, and filling the remainder of each recess with substrate material.

    摘要: A semiconductor device and method of manufacture provide an n-channel field effect transistor (nFET) having a shallow trench isolation with overhangs that overhang Si—SiO2 interfaces in a direction parallel to the direction of current flow and in a direction transverse to current flow. The device and method also provide a p-channel field effect transistor (pFET) having a shallow trench isolation with an overhang that overhangs Si—SiO2 interfaces in a direction transverse to current flow. However, the shallow trench isolation for the pFET is devoid of overhangs, in the direction parallel to the direction of current flow.

    摘要: A semiconductor device has selectively applied thin tensile films and thin compressive films, as well as thick tensile films and thick compressive films, to enhance electron and hole mobility in CMOS circuits. Fabrication entails steps of applying each film, and selectively removing each applied film from areas that would not experience performance benefit from the applied stressed film.
