Abstract:
A planarization process is performed to a wafer. In various embodiments, the planarization process may include a chemical mechanical polishing (CMP) process. A byproduct generated by the planarization process is collected and analyzed. Based on the analysis, one or more process controls are performed for the planarization process. In some embodiments, the process controls include but are not limited to process endpoint detection or halting the planarization process based on detecting an error associated with the planarization process.

Claim (Index 14):
A method, comprising:\n performing a chemical mechanical polishing (CMP) process to a wafer, wherein the CMP process is performed using a CMP tool that includes a polishing unit and a cleaning unit; capturing liquid samples of a byproduct produced by the polishing unit or by the cleaning unit; applying a ray or a wave to the captured liquid samples of the byproduct; measuring a response of the captured liquid samples to the applied ray or wave; determining, based on the measured response, what elements are included in the byproduct; and performing a CMP process control based on the determining.
