  • Publication number: 20080044966
    Abstract: The present invention provides a semiconductor material that has enhanced electron and hole mobilities that comprises a Si-containing layer having a <110> crystal orientation and a biaxial compressive strain. The term “biaxial compressive stress” is used herein to describe the net stress caused by longitudinal compressive stress and lateral stress that is induced upon the Si-containing layer during the manufacturing of the semiconductor material. Other aspect of the present invention relates to a method of forming the semiconductor material of the present invention. The method of the present invention includes the steps of providing a silicon-containing <110> layer; and creating a biaxial strain in the silicon-containing <110> layer.

  • Publication number: 20070184619
    Abstract: A device and method for selective placement of charge into a gate stack includes forming gate stacks including a gate dielectric adjacent to a transistor channel and a gate conductor and forming doped regions for transistor operation. A layer rich in a passivating element is deposited over the doped regions and the gate stack, and the layer rich the passivating element is removed from selected transistors. The layer rich in the passivating element is than annealed to drive-in the passivating element to increase a concentration of charge at or near transistor channels on transistors where the layer rich in the passivating element is present. The layer rich in the passivating element is removed.

  • Publication number: 20070158743
    Abstract: The present invention provides a semiconducting device structure including a thin SOI region, wherein the SOI device is formed with an optional single thin diffusion, i.e., offset, spacer and a single diffusion implant. The device silicon thickness is thin enough to permit the diffusion implants to abut the buried insulator but thick enough to form a contacting silicide. Stress layer liner films are used both over nFET and pFET device regions to enhance performance.
