摘要
Exemplary methods for detecting substrate slippage include sweeping a first sensor and a second sensor of an in-situ monitoring system across the substrate as the substrate undergoes polishing with a rotatable platen. A first sequence of signal values from the first sensor and a second sequence of signal values from the second sensor include a signal strength relative to the thickness of the layer.…
