Abstract:
A field effect transistor includes a channel made of germanium and a source/drain portion. The source/drain portion includes a germanium layer, an interfacial epitaxial layer over the germanium layer, a semiconductor layer over the interfacial epitaxial layer, and a conducting layer over the semiconductor layer. The interfacial epitaxial layer contains germanium and an element from the semiconductor layer and has a thickness in a range from about 1 nm to about 3 nm.

Claim (Index 21):
A method of forming a source/drain-structure in a semiconductor device, the method comprising:\n forming a first interfacial epitaxial layer over a first semiconductor layer disposed over a substrate; forming a second interfacial epitaxial layer over the first interfacial epitaxial layer; forming a second semiconductor layer over the second interfacial epitaxial layer; wherein the first interfacial epitaxial layer includes a first element from the first semiconductor layer and a second element from the second semiconductor layer, and wherein the second interfacial epitaxial layer includes the first element from the first semiconductor layer and the second element from the second semiconductor layer; and forming a conductive layer over the second semiconductor layer.
