Method of determining the endpoint of a planarization process |
摘要 |
A method of determining the endpoint of a planarizing process is disclosed. An endpoint detection signal is selectively sampled from at least one predetermined location within a planarizing region defined on a planarizing web. Planarization is stopped when the endpoint criterion based on the endpoint detection signal is detected.
