WebJul 28, 2024 · Chemical mechanical polishing (CMP) is one of the key processes in wafer-level packaging. CMP is a process that removes materials by a combination of chemical and mechanical actions to achieve highly smooth and planar material surfaces. Achieving a planar surface through a CMP process is expensive, which is one of the shortcomings of … 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.

WebJan 24, 2024 · The CMP process is performed by two parts – the polisher part and the cleaning part. In the polisher part, the slurry is injected onto the surface of the wafer and pad to polish off the wafer surface. And in the … 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
WebChemical Mechanical Planarization (CMP) is “a process of smoothing wafer surfaces with the combination of chemical and mechanical forces” [8]. The main reason for using a hybrid of chemical etching and free abrasive polishing is because mechanical grinding alone causes too much damage to the wafer
