Abstract:
1. A structure comprising: a substrate comprised of crystalline silicon, the substrate including a body portion and a plurality of first fins comprised of crystalline silicon extending from and integral with the body portion; a plurality of second fins, each of the second fins including a crystalline silicon base integral with the body portion of the substrate and a silicon germanium portion adjoining the silicon base, the plurality of second fins being parallel to the plurality of first fins, one or more of the first and second fins being within less than 30 nm of at least one or more of another one or more of the first and second fins; a plurality of dielectric caps, each dielectric cap adjoining a top surface of each of the first and second fins; an intermediate region including a silicon portion integral with the body portion of the substrate and a silicon germanium portion adjoining the silicon portion, the intermediate region and the first and second fins being substantially equal in height, and a mask adjoining a top surface of the intermediate region.
