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 1):
A method of forming a source/drain-structure in a semiconductor device, the method comprising:\n forming an interfacial epitaxial layer over a first semiconductor layer disposed over a substrate; forming a second semiconductor layer over the interfacial epitaxial layer; and forming a conductive layer over the second semiconductor layer.
