摘要: A transistor includes a notched fin covered under a shallow trench isolation layer. One or more notch may be used, the size of which may vary along a lateral direction of the fin. In some embodiments, The notch is formed using anisotropic wet etching that is selective according to silicon orientation. Example wet etchants are tetramethylammonium hydroxide (TMAH) or potassium hydroxide (KOH).

摘要: An integrated circuit device and method for manufacturing the integrated circuit device are disclosed. The disclosed method comprises forming a wedge-shaped recess with an initial bottom surface in the substrate; transforming the wedge-shaped recess into an enlarged recess with a height greater than the height of the wedge-shaped recess; and epitaxially growing a strained material in the enlarged recess.
