Webremoval rate as long as the CMP process takes place in the lubrication regime where the wafer is not in direct contact with the pad. Tichy et al. (1999) developed another model in which the CMP process is regarded as a contact problem of a wafer on a rough pad lubricated by a slurry. The slurry lm thickness is controlled by the height WebCMP is performed using a small particle abrasive chemical slurry and a polishing pad. This process provides more planarization than mechanical grinding, although it tends to be less clean. Chemical mechanical planarization takes place in three steps: Mount the wafers to a backside film, like a wax mount, in order to hold them in place.
