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. The scavenging material is distributed within the oxygen-scavenging-material-including gate spacer in a manner that prevents an electrical short between a gate electrode and a semiconductor material underlying a gate dielectric. The scavenging material actively scavenges oxygen that diffuses toward the gate dielectric from above, or from the outside of, a dielectric gate spacer that can be formed around the oxygen-scavenging-material-including gate spacer.

Abstract: A mechanism is provided for reusing importance sampling for efficient cell failure rate estimation of process variations and other design considerations. First, the mechanism performs a search across circuit parameters to determine failures with respect to a set of performance variables. For a single failure region, the initial search may be a uniform sampling of the parameter space. Mixture importance sampling (MIS) efficiently may estimate the single failure region. The mechanism then finds a center of gravity for each metric and finds importance samples. Then, for each new origin corresponding to a process variation or other design consideration, the mechanism finds a suitable projection and recomputes new importance sampling (IS) ratios.
