Patent number: 11901203Abstract: Methods and systems for detection of an endpoint of a substrate process are provided. A set of machine learning models are trained to provide a metrology measurement value associated with a particular type of metrology measurement for a substrate based on spectral data collected for the substrate. A respective machine learning model is selected to be applied to future spectral data collected during a future substrate process for a future substrate in view of a performance rating associated with the particular type of metrology measurement. Current spectral data is collected during a current process for a current substrate and provided as input to the respective machine learning model. An indication of a respective metrology measurement value corresponding to the current substrate is extracted from one or more outputs of the trained machine learning model.Type: GrantFiled: June 10, 2021Date of Patent: February 13, 2024Assignee: Applied Materials, Inc.Inventors: Pengyu Han, Lei Lian, Shu Yu Chen, Todd Egan, Wan Hsueh Lai, Chao-Hsien Lee, Pin Ham Lu, Zhengping Yao, Barry Craver

Publication number: 20230306281Abstract: A method includes determining that conditions of a processing chamber have changed since a trained machine learning model associated with the processing chamber was trained. The method further includes determining whether a change in the conditions of the processing chamber is a gradual change or a sudden change. Responsive to determining that the change in the conditions of the processing chamber is a gradual change, the method further includes performing a first training process to generate a new machine learning model. Responsive to determining that the change in the conditions of the processing chamber is a sudden change, the method further includes performing a second training process to generate the new machine learning model. The first training process is different from the second training process.Type: ApplicationFiled: February 9, 2022Publication date: September 28, 2023Inventors: Pengyu Han, Hong-Rui Chen, Shu-Yu Chen, Wan-Hsueh Lai, Pin Ham Lu, Zhengping Yao
