Abstract: At least one layer including a scavenging material and a dielectric material is deposited over a gate stack, and is subsequently anisotropically etched to form a oxygen-scavenging-material-including gate spacer. The oxygen-scavenging-material-including gate spacer can be a scavenging-nanoparticle-including gate spacer or a scavenging-island-including gate spacer.
