Title: Innovations by Inventor Jian-Huei Feng
Introduction
Jian-Huei Feng is a notable inventor based in San Jose, CA, with a focus on process control technologies. He holds 5 patents that contribute significantly to advancements in the field. His work primarily revolves around methods for enhancing process control in various applications.
Latest Patents
Feng's latest patents include innovative methods for providing run-to-run process control using a dynamic tuner. This method involves receiving a data point for a process output parameter and determining its alignment with a desired range. When the data point is within the desired range, a dynamic lambda value is set to a preselected base lambda value. Conversely, if the data point falls outside this range, the dynamic lambda value is adjusted based on the difference between the data point and the target, along with a scale factor. This process culminates in calculating an exponentially weighted moving average to adjust the process control parameter accordingly.
Another significant patent by Feng describes methods for providing asymmetric run-to-run control of process parameters. This method includes receiving a data point for a process parameter relative to a wafer and selecting different values for a process weighting factor based on specific criteria. The exponential weighted moving average of the process parameter is then calculated and used to control the process effectively.
