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 The process uses an abrasive and corrosive chemical slurry (commonly a colloid) in conjunction with a polishing pad and retaining ring, typically of a greater diameter than the wafer. The pad and wafer are pressed together by a dynamic polishing head and held in place by a plastic retaining ring. The dynamic polishing head is rotated with different axes of rotation (i.e., not concentric). Th… highway 1 hope to boston bar
