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 1):
A semiconductor device, comprising:\n a semiconductor substrate; a protrusion part formed on the semiconductor substrate such that the protrusion part extends along a first direction; a gate dielectric layer covering the protrusion part; a gate electrode formed on the gate dielectric layer such that the gate electrode covers the protrusion part through the gate dielectric layer; a source region formed next to a part covered with the gate electrode in the protrusion part; and 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 protrusion part, wherein the protrusion part comprising: a first region composed of a first semiconductor material; and a second region formed next to the first region, the second region composed of a second semiconductor material having a lattice constant different from a lattice constant of the first semiconductor material, and wherein the second region is formed between the source region and the drain region in a first cross-sectional view through the source region, the drain region and the gate electrode.
