    摘要: Apparatus and methods for conditioning a polishing pad in a CMP system are provided. In one embodiment, a method includes performing a pre-polish process including urging a conditioner disk against a polishing surface of a polishing pad disposed in a polishing station, moving the conditioner disk relative to the polishing pad in a sweep pattern across the polishing surface while monitoring a rotational force value required to move the conditioner disk relative to the polishing pad, determining a metric indicative of an interaction between the conditioner disk and the polishing surface from the rotational force value, adjusting a polishing recipe in response to the metric, and polishing one or more substrates using the adjusted polishing recipe.

    摘要: Embodiments of the present invention generally relate to methods for chemical mechanical polishing a substrate. The methods generally include measuring the thickness of a polishing pad having grooves or other slurry transport features on a polishing surface. Once the depth of the grooves on the polishing surface is determined, a flow rate of a polishing slurry is adjusted in response to the determined groove depth. A predetermined number of substrates are polished on the polishing surface. The method can then optionally be repeated.

    摘要: A substrate having a plurality of zones is polished and spectra are measured. For each zone, a first linear function fits a sequence of index values associated with reference spectra that best match the measured spectra. A projected time at which a reference zone will reach the target index value is determined based on the first linear function, and for at least one adjustable zone, a polishing parameter adjustment is calculated such that the adjustable zone has closer to the target index at the projected time than without such adjustment. The adjustment is calculated based on a feedback error calculated for a previous substrate. The feedback error for a subsequent substrate is calculated based on a second linear function that fits a sequence of index values associated with reference spectra that best match spectra measured after the polishing parameter is adjusted.
