An oxide or nitride semiconductor layer is formed over a substrate. A first conductive layer including a first element and a second element, and a second conductive layer including the second element are formed over the semiconductor layer. The first element is oxidized or nitrogenized near an interface region between the first conductive layer and the oxide or nitride semiconductor layer by heat treatment or laser irradiation.

A stack of a high-k gate dielectric and a metal gate structure includes a lower metal layer, a scavenging metal layer, and an upper metal layer. The scavenging metal layer meets the following two criteria 1) a metal (M) for which the Gibbs free energy change of the reaction Si+2 / y MxOy→2x / y M+SiO2 is positive 2) a metal that has a more negative Gibbs free energy per oxygen atom for formation of oxide than the material of the lower metal layer and the material of the upper metal layer. The scavenging metal layer meeting these criteria captures oxygen atoms as the oxygen atoms diffuse through the gate electrode toward the high-k gate dielectric. In addition, the scavenging metal layer remotely reduces the thickness of a silicon oxide interfacial layer underneath the high-k dielectric. As a result, the equivalent oxide thickness (EOT) of the total gate dielectric is reduced and the field effect transistor maintains a constant threshold voltage even after high temperature processes during CMOS integration.

A nonvolatile resistive memory element includes an oxygen-gettering layer. The oxygen-gettering layer is formed as part of an electrode stack, and is more thermodynamically favorable in gettering oxygen than other layers of the electrode stack.
