Patent ID: 7109121

Claim:
A method of forming a semiconductor microstructure comprising: (a) providing a semiconductor structure including at least a layer of semiconductor film over a sacrificial layer, the semiconductor film secured to a substrate; (b) depositing a film of material over the semiconductor film that has a tensile or compressive strain with respect to the semiconductor film; (c) patterning the deposited film to leave opposed segments spaced from each other by a central portion of the semiconductor film; (d) patterning the semiconductor film and removing the sacrificial layer beneath the patterned semiconductor film to leave a suspended semiconductor film section anchored to the substrate at at least two opposed anchor positions, with the film segments remaining on the semiconductor film adjacent to the anchor positions and spaced from each other by the central portion of the suspended semiconductor film such that the film segments apply a tensile or compressive stress to the suspended semiconductor film; and (e) depositing another semiconductor film over the central portion of the stressed suspended semiconductor film.
