Abstract:
An integrated circuit containing an n-channel finFET and a p-channel finFET is formed by forming a first polarity fin epitaxial layer for a first polarity finFET, and subsequently forming a hard mask which exposes an area for a second, opposite, polarity fin epitaxial layer for a second polarity finFET. The second polarity fin epitaxial layer is formed in the area exposed by the hard mask. A fin mask defines the first polarity fin and second polarity fin areas, and a subsequent fin etch forms the respective fins. A layer of isolation dielectric material is formed over the substrate and fins. The layer of isolation dielectric material is planarized down to the fins. The layer of isolation dielectric material is recessed so that the fins extend at least 10 nanometers above the layer of isolation dielectric material. Gate dielectric layers and gates are formed over the fins.

Claim (Index 7):
An integrated circuit, comprising:\n a silicon substrate; an n channel fin field effect transistor (finFET), comprising:\n a first buffer disposed on the silicon substrate, said first buffer comprising germanium; \n an n channel fin disposed on the first buffer, said n channel fin comprising GaAs; \n a first gate dielectric layer disposed over the n channel fin; and \n a first gate disposed over the first gate dielectric layer; \n a p channel finFET, comprising:\n a p channel fin disposed over the silicon substrate, said p channel fin comprising germanium; \n a second gate dielectric layer disposed over the p channel fin; and \n a second gate disposed over the second gate dielectric layer; and \n an isolation dielectric layer disposed over the silicon substrate around the first buffer and the n channel fin and around the p channel fin, such that the n channel fin and the p channel fin extend above the isolation dielectric layer.
