发明名称 Polishing control using weighting with default sequence
摘要 A method of controlling polishing includes storing a sequence of default values, polishing a substrate, monitoring the substrate during polishing with an in-situ monitoring system, generating a sequence of measured values from measurements from the in-situ monitoring system, combining the sequence of measured values with the sequence of default values to generate a sequence of modified values, fitting a function to the sequence of modified values, and determining at least one of a polishing endpoint or an adjustment for a polishing rate based on the function.

主权项 1. A method of controlling polishing, comprising: storing a sequence of default values; polishing a substrate; monitoring the substrate during polishing with an in-situ monitoring system; generating a sequence of measured values from measurements from the in-situ monitoring system; combining the sequence of measured values with the sequence of default values to generate a sequence of modified values; fitting a function to the sequence of modified values; and determining at least one of a polishing endpoint or an adjustment for a polishing rate based on the function.
