  • Patent number: 10269630
    Abstract: A semiconductor device and method of formation are provided. The semiconductor device comprises a metal plug in a first opening over a substrate, the metal plug is over a silicide layer, and the silicide layer is over a metal oxide layer. The metal oxide layer has an oxygen gradient, such that a percentage of oxygen increases from a top surface of the metal oxide layer to a bottom surface of the metal oxide layer. The metal oxide layer unpins the Fermi level of the interface between the metal plug and the substrate, which is exhibited by a lowered Schottky barrier height (SBH) and increased oxygen vacancy states between the V.B. and the C.B. of the metal oxide layer, which decreases the intrinsic resistivity between the metal plug and the substrate as compared to a semiconductor device that lacks such a metal oxide layer.
