Classification: CPC H | IPC H

Claim 8:
9. A semiconductor device, comprising:
a first fin structure disposed over a substrate;
a second fin structure disposed over the substrate;
a first conductive layer disposed over an upper part of the first fin structure;
a second conductive layer disposed over an upper part of the second fin structure;
a third conductive layer covering the first conductive layer and the second conductive layer; and
a contact plug contacting the third conductive layer,
wherein the third conductive layer is separated from the first fin structure by a dielectric layer, and
each of the first conductive layer and the second conductive layer includes an alloy layer of one or more Group IV elements and one or more transition metal elements.
