150MM CMP RETAINER RING
Chemical Mechanical Polishing is more commonly known as CMP. It is a planarization process of smoothing surfaces with the combination of chemical and mechanical forces in semiconductor manufacturing. Our CMP retainer ring products is installed on the polishing head of the polishing machine, clamp the wafer to prevent debris without departing from the polishing head, while the slurry is introduced into the polishing head for uniformly polishing.
