Latest Patents

One of his latest patents is titled "Method and apparatus for endpoint detection using partial least squares." This invention provides an apparatus and method for detecting feature etch completion within an etching reactor. The method involves determining a correlation matrix by recording first measured data regarding a first etch process over successive time intervals to form a first recorded data matrix. It also includes assembling a first endpoint signal matrix using target endpoint data for a specific etch process, performing a partial least squares analysis on the recorded data matrix and the first endpoint signal matrix to refine the recorded data matrix, and computing a correlation matrix based on the refined recorded data matrix and the first endpoint signal matrix. Furthermore, the method entails performing a second etch process to form a second recorded data matrix, where the correlation matrix and the second recorded data matrix are analyzed to determine whether the endpoint of the second etch process has been achieved.

Another significant patent is the "Method for automatic configuration of processing system." This method focuses on automatically configuring an Advanced Process Control (APC) system for a semiconductor manufacturing environment. It involves generating an auto-configuration script for executing an auto-configuration program, which activates default values for input. The script is executed to produce an enabled parameter file output from the auto-configuration program, identifying parameters for statistical process control (SPC) chart generation.
