摘要: A method is provided for forming grooves in a polishing pad useful for planarizing a substrate in a chemical mechanical planarization process. The method maintains average velocity as a function of bit diameter to enable groove formation using a rotating bit, whereby grooves can be formed at a higher rate while maintaining high groove quality and low defectivity.
