A method to form a strain-inducing epitaxial film is described. In one embodiment, the strain-inducing epitaxial film is a three-component epitaxial film comprising atoms from a parent film, charge-neutral lattice-substitution atoms and charge-carrier dopant impurity atoms. In another embodiment, the strain-inducing epitaxial film is formed by a multiple deposition/etch cycle sequence involving hydrogenated amorphous silicon, followed by charge carrier dopant and charge-neutral lattice-forming impurity atom implant steps and, finally, a kinetically-driven crystallization process.
