Abstract:
A semiconductor device includes a field effect transistor (FET). The FET includes a first channel, a first source and a first drain; a second channel, a second source and a second drain; and a gate structure disposed over the first and second channels. The gate structure includes a gate dielectric layer and a gate electrode layer. The first source includes a first crystal semiconductor layer and the second source includes a second crystal semiconductor layer. The first source and the second source are connected by an alloy layer made of one or more Group IV element and one or more transition metal elements. The first crystal semiconductor layer is not in direct contact with the second crystal semiconductor layer.

Claim (Index 1):
A method of manufacturing a semiconductor device including a field effect transistor (FET), the method comprising:\n forming a first fin and a second fin by patterning a substrate; forming a first insulating layer over the substrate so that upper portions of the first and second fins project form the first insulating layer; forming a dummy gate structure over the projecting first and second fins; after the dummy gate structure is formed, recessing the first and second fins; forming a first epitaxial semiconductor layer and a second epitaxial semiconductor layer on the first recessed fin and the second recessed fin, respectively; forming the second insulating layer so as to cover the first and second epitaxial semiconductor layers; forming an alloy layer over the first and second epitaxial semiconductor layers, wherein: the first epitaxial layer and the second epitaxial semiconductor layer are in contact with and connected by the alloy layer, and the first epitaxial semiconductor layer is not in direct contact with the second epitaxial semiconductor layer, and the alloy layer wraps around the first and second epitaxial semiconductor layers.
