    摘要: 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.
