Latest Patents

One of his latest patents is titled "System for multiresolution analysis assisted reinforcement learning approach to run-by-run control." This invention introduces a new multiresolution analysis (wavelet) assisted reinforcement learning (RL) based control strategy. It effectively addresses multiscale disturbances in processes and the absence of process models. The WRL-RbR controller, as it is termed, has been tested on a multiple-input-multiple-output (MIMO) Chemical Mechanical Planarization (CMP) process. Results indicate that this RL controller outperforms traditional EWMA based controllers, particularly in low autocorrelation scenarios. Additionally, the controller shows promising performance in strongly autocorrelated processes where EWMA controllers typically fail.

Another significant patent is "System and method for online end point detection for use in chemical mechanical planarization." This invention presents a robust and cost-effective online methodology for end point detection in CMP processes. It overcomes several limitations of existing detection approaches. The system identifies significant events in the CMP process by decomposing coefficient of friction data using wavelet-based multiresolution analysis and applying a sequential probability ratio test for variance on the decomposed data.
