    摘要: A method of forming an integrated circuit structure includes providing a wafer having a silicon substrate; forming a plurality of shallow trench isolation (STI) regions in the silicon substrate; and forming recesses by removing top portions of the silicon substrate between opposite sidewalls of the plurality of STI regions. Substantially all long sides of all recesses in the silicon substrate extend in a same direction. A III-V compound semiconductor material is then epitaxially grown in the recesses.

    摘要: Abstract of the Disclosure A method of forming a channel region for a MOSFET device in a strained silicon layer via employment of adjacent and surrounding silicon-germanium shapes, has been developed. The method features simultaneous formation of recesses in a top portion of a conductive gate structure and in portions of the semiconductor substrate not occupied by the gate structure or by dummy spacers located on the sides of the conductive gate structure. The selectively defined recesses will be used to subsequently accommodate silicon-germanium shapes, with the silicon-germanium shapes located in the recesses in the semiconductor substrate inducing the desired strained channel region. The recessing of the conductive gate structure and of semiconductor substrate portion reduces the risk of silicon-germanium bridging across the surface of sidewall spacers during epitaxial growth of the alloy layer, thus reducing the risk of gate to substrate leakage or shorts.
