Abstract: Embodiments of the present disclosure describe semiconductor devices comprised of a semiconductor substrate with a metal oxide semiconductor field effect transistor having a channel including germanium or silicon-germanium, where a dielectric layer is coupled to the channel. The dielectric layer may include a metal oxide and at least one additional element, where the at least one additional element may increase a band gap of the dielectric layer. A gate electrode may be coupled to the dielectric layer. Other embodiments may be described and/or claimed.

Abstract: Techniques are disclosed for forming transistor devices having reduced interfacial resistance in a local interconnect. The local interconnect can be a material having similar composition to that of the source/drain material. That composition can be a metal alloy of a group IV element such as nickel germanide. The local interconnect of the semiconductor integrated circuit can function in the absence of barrier and liner layers. The devices can be used on MOS transistors including PMOS transistors.
