  • Patent number: 11669072
    Abstract: Information about a process for depositing at least one layer on a substrate in a process chamber is obtained via a method including the step of storing actuation data and sensor values as raw data in a log file, together with their time reference. Knowledge about the quality of the deposited layer is obtained by using the raw data. For this purpose, process parameters are obtained from the raw data by means of a computing apparatus. The beginning and the end of the process steps for processing the substrate and their respective types are identified by analyzing the time curve of the process parameters. For at least some of the process steps, characteristic process step quantities corresponding to the particular type of the process steps are calculated from the measured values, and the obtained process step quantities are compared with comparison quantities associated with one or more similar process steps.
