Abstract:
A non-planar semiconductor structure, for example, a dual FinFET structure, includes a n-type semiconductor device and a p-type semiconductor device. Metal-insulator-semiconductor (MIS) contacts provide electrical connection to the n-type device, and metal-semiconductor (MS) contacts provide electrical connection to the p-type device. The metal of both MIS and MS contacts is a same n-type work function metal. In one example, the semiconductor of the MIS contact includes epitaxial silicon germanium with a relatively low percentage of germanium, the insulator of the MIS contact includes titanium dioxide, the semiconductor for the MS contact includes silicon germanium with a relatively high percentage of germanium or pure germanium, and the metal for both contacts includes a n-type work function metal.
