  • Patent number: 11973661
    Abstract: Embodiments of the invention are directed to a computer system that includes a memory electronically coupled to a processor system. The processor system is operable to perform processor system operations that include accessing a graph model representation of a computer network. The graph model is used to implement a resiliency-problem identification analysis that identifies a set of resiliency problems in the graph model. The graph model is used to apply a resiliency-problem solution analysis to a resiliency problem in the set of resiliency problems to generate a set of resiliency-problem solutions. Each resiliency-problem solution in the set of resiliency-problem solutions is ranked.

  • Patent number: 11713508
    Abstract: Processing chambers and methods to disrupt the boundary layer are described. The processing chamber includes a showerhead and a substrate support therein. The showerhead and the substrate support are spaced to have a process gap between them. In use, a boundary layer is formed adjacent to the substrate support or wafer surface. As the reaction occurs at the wafer surface, reaction products and byproduct are produced, resulting in reduced chemical utilization rate. The processing chamber and methods described disrupt the boundary layer by changing one or more process parameters (e.g., pressure, flow rate, time, process gap or temperature of fluid passing through the showerhead).

  • Patent number: 11586789
    Abstract: Methods, software systems and processes to develop surrogate model-based optimizers for controlling and optimizing flow and pressure of purges between a showerhead and a heater having a substrate support to control non-uniformity inherent in a processing chamber due to geometric configuration and process regimes. The flow optimizer process utilizes experimental data from optimal process space coverage models, generated simulation data and statistical machine learning tools (i.e. regression models and global optimizers) to predict optimal flow rates for any user-specified process regime.
