  • Publication number: 20250085699
    Abstract: A method, apparatus, and system for controlling a physical twin chamber configured to process substrates are described herein. In some embodiments, a method comprises determining, by a digital twin device, characteristics of a physical twin chamber and generating control inputs for controlling the physical twin chamber. The digital twin device comprises one or more computational models for determining the characteristics of the physical twin and for generating the control inputs. The digital twin device determines a first data set associated with the physical twin chamber. The first data set comprises process data collected by sensors configured to measure attributes of the physical twin chamber. Based on the first data, the digital twin device automatically generates a second data set based on the generated control inputs and transmits the second data set to the physical twin chamber for controlling the process performed on the substrates by the physical twin chamber.

  • Publication number: 20230222264
    Abstract: A method includes receiving, from sensors, sensor data associated with processing a substrate via a processing chamber of substrate processing equipment. The sensor data includes a first subset received from one or more first sensors and a second subset received from one or more second sensors, the first subset being mapped to the second subset. The method further includes identifying model input data and model output data. The model output data is output from a physics-based model based on model input data. The method further includes training a machine learning model with data input including the first subset and the model input data, and target output data including the second subset and the model output data to tune calibration parameters of the machine learning model. The calibration parameters are to be used by the physics-based model to perform corrective actions associated with the processing chamber.

  • Patent number: 11586160
    Abstract: Methods and systems for reducing substrate particle scratching using machine learning are provided. A machine learning model is trained to predict process recipe settings for a substrate temperature control process to be performed for a current substrate at a manufacturing system. First training data and second training data are generated for the machine learning model. The first training data includes historical data associated with prior process recipe settings for a prior substrate temperature control process performed for a prior substrate at a prior process chamber. The second training data is associated with a historical scratch profile of one or more surfaces of the prior substrate after performance of the prior substrate temperature control process according to the prior process recipe settings.
