  • Publication number: 20220270237
    Abstract: Defects on a substrate comprising electronic components can be classified with a computational defect analysis system that may be implemented in multiple stages. For example, a first stage classification engine may process metrology data to produce an initial classification of defects. A second stage classification engine may use the initial classification, along with manufacturing information and/or prior defect knowledge to output probabilities that the defects are caused by one or more potential sources.

  • Patent number: 10977405
    Abstract: Provided herein are systems and methods for optimizing feature fill processes. The feature fill optimization systems and methods may be used to optimize feature fill from a small number of patterned wafer tests. The systems and methods may be used for optimizing enhanced feature fill processes including those that include inhibition and/or etch operations along with deposition operations. Results from experiments may be used to calibrate a feature scale behavioral model. Once calibrated, parameter space may be iteratively explored to optimize the process.

  • Patent number: 10895539
    Abstract: A system includes a camera mounted external to and adjacent to a window of a processing chamber configured to process semiconductor substrates. The window allows the camera to view a component in the processing chamber. The camera is configured to generate a video signal indicative of a status of the component during a process being performed in the processing chamber. The system further includes a controller coupled to the processing chamber. The controller is configured to control the camera, process the video signal from the camera, determine the status of the component based on the processing of the video signal, and determine whether to terminate the process based on the status of the component.
