Abstract:
A method for producing a finFET having a fin with thinned sidewalls on a lower portion above a shallow trench isolation (STI) regions is provided. Embodiments include forming a fin surrounded by STI regions on a substrate; recessing the STI regions, revealing an upper portion of the fin; forming a spacer over side and upper surfaces of the upper portion of the fin; recessing the STI regions, exposing a lower portion of the fin; and thinning sidewalls of the lower portion of the fin.

Claim (Index 12):
A device comprising:\n a fin formed on a semiconductor substrate; and a shallow trench isolation (STI) region formed on sides of the fin, wherein a lower portion of the fin, exposed above an upper surface of the STI region, includes a semi-ellipsoid shape in each side of the fin, the semi-ellipsoid shape having a depth of 1 to 5 nm into the sides of the fin.
