  • Automatic window generation for process trace
    Patent number: 11687439
    Abstract: Automatic definition of windows for trace analysis. For each process step, the trace data are aligned to both the start of the process step and the end of the process step, and statistics including rate of change are calculated from both the start of the process step and the end of the process step. Windows are generated based on analysis of the calculated statistics.
    Type: Grant
    Filed: July 22, 2021
    Date of Patent: June 27, 2023
    Assignee: PDF Solutions, Inc.
    Inventors: Richard Burch, Kazuki Kunitoshi, Michio Aruga, Nobichika Akiya
  • Predicting equipment fail mode from process trace
    Patent number: 11640328
    Abstract: A predictive model for equipment fail modes. An anomaly is detected in a collection of trace data, then key features are calculated. A search is conducted for the same or similar anomalies having the same key features in a database of past trace data. If the same anomaly occurred before and is in the database, then the type of anomaly, its root cause, and action steps to correct can be retrieved from the database.
