    Abstract: A method to form a strain-inducing semiconductor region comprising three or more species of charge-neutral lattice-forming atoms is described. In one embodiment, formation of a strain-inducing semiconductor region, comprising three or more species of charge-neutral lattice-forming atoms, laterally adjacent to a crystalline substrate results in a uniaxial strain imparted to the crystalline substrate. Thus, a strained crystalline substrate may be provided. In another embodiment, a semiconductor region with a crystalline lattice of three or more species of charge-neutral lattice-forming atoms imparts a strain to a crystalline substrate, wherein the lattice constant of the semiconductor region is different from that of the crystalline substrate.

    Abstract: In general, in one aspect, a method includes using the Germanium nanowire as building block for high performance logic, memory and low dimensional quantum effect devices. The Germanium nanowire channel and the SiGe anchoring regions are formed simultaneously through preferential Si oxidation of epitaxial Silicon Germanium epi layer. The placement of the germanium nanowires is accomplished using a Si fin as a template and the germanium nanowire is held on Si substrate through SiGe anchors created by masking the two ends of the fins. High dielectric constant gate oxide and work function metals wrap around the Germanium nanowire for gate-all-around electrostatic channel on/off control, while the Germanium nanowire provides high carrier mobility in the transistor channel region. The germanium nanowire transistors enable high performance, low voltage (low power consumption) operation of logic and memory devices.
