Abstract:
A semiconductor device and method making it utilize a three-dimensional channel region comprising a core of a first semiconductor material and an epitaxial covering of a second semiconductor material. The first and second semiconductor materials have respectively different lattice constants, thereby to create a strain in the epitaxial covering. The devices are formed by a gate-last process, so that the second semiconductor material is deposited only after the high temperature processes have been performed. Consequently, the lattice strain is not substantially relaxed, and the improved performance benefits of the lattice strained channel region are not compromised.

Claim (Index 13):
A method of manufacturing a semiconductor device, comprising;\n forming an intermediate transistor; the intermediate transistor comprising;\n a semiconductor substrate; \n a core region formed on the semiconductor substrate such that the core region extends along a first direction, the core region comprised of a first semiconductor material; \n a dummy gate covering the core region; \n a source region formed next to a part covered with the dummy gate in the core region; and \n a drain region formed at a position opposed to the source region, the portion covered with the gate electrode sandwiched between the source region and the drain region in the core region, \n removing the dummy gate from the intermediate transistor to expose a part of the core region; forming an epitaxial film on a part of the core region, the epitaxial film composed of a second semiconductor material having a lattice constant different from a lattice constant of the first semiconductor material; forming a gate dielectric layer so as to cover the core region through the epitaxial film, and forming a gate electrode so as to cover the core region through the gate dielectric layer.
