We demonstrate a novel metal stanogermanide contact metallization process for high mobility germanium-tin (GeSn) channel MOSFETs. The multi-phase nickel-platinum stanogermanide [Ni(GeSn)+Ptx(GeSn)y] contacts are formed by reacting Ni-Pt alloy with Ge0.947Sn0.053 alloy, which is epitaxially grown on Ge (100) substrate by solid source molecular beam epitaxy (MBE). Compared with nickel stanogermanide [Ni(GeSn)] contacts, the Pt-incorporated contacts, i.e. [Ni(GeSn)+Ptx(GeSn)y], exhibit enhanced thermal stability in a wide range of formation temperatures and have superior surface morphology even after thermal processing. The proposed contacts are attractive for the integration in high mobility GeSn MOSFETs.
