A semiconductor device and a method of fabricating a contact to interface with an interconnect in a semiconductor device are described. The device includes a dielectric layer formed on a semiconductor layer, and a contact fabricated in a via formed within the dielectric layer. An interconnect formed above the contact interfaces with an exposed surface of the contact opposite a surface closest to the semiconductor layer. The contact includes a contact material in a first portion of the contact and an interface metal in a second portion of the contact.
