Abstract

Techniques are provided herein to form semiconductor devices having nanowires with an increased strain. A thin layer of silicon germanium or germanium tin can be deposited over one or more suspended nanoribbons. An anneal process may then be used to drive the silicon germanium or germanium tin throughout the one or more semiconductor nanoribbons, thus forming one or more nanoribbons with a changing material composition along the lengths of the one or more nanoribbons. In some examples, at least one of the one or more nanoribbons includes a first region at one end of the nanoribbon having substantially no germanium, a second region at the other end of the nanoribbon having substantially no germanium, and a third region between the first and second regions having a substantially uniform non-zero germanium concentration. The change in material composition along the length of the nanoribbon imparts a compressive strain.
