Chemical Mechanical Planarization (CMP) Slurries Information. CMP is a surface polishing and material removal process involving both chemical attack and abrasive removal. CMP slurries are used in conjunction with CMP pads or polishing naps, which are rotated and held against a substrate or wafer surface during the planarization process.

Chemical Mechanical Planarization (CMP) is a process that is used to remove topography from silicon oxide, metal and polysilicon surfaces. In layman's language, it is a used for smoothen surfaces with the combination of chemical and mechanical forces and hence in a way, be thought of as a hybrid of chemical etching and free abrasive polishing.

mechanical effect provided by polishing to reduce topography on the wafer surface. This process uses a "Tool" with a rotating wafer carrier (single or multihead) and a polishing pad placed on a rotating platen. Wafers are held in the carrier and pressed against the polishing pad onto which chemical abrasive polishing

To do this, chipmakers use a process called chemicalmechanical planarization, or CMP, for short. CMP involves pouring a mixture of chemicals and sand (moreorless) on a spinning disc of special sandpaper and polishing away. At one time, the CMP process was viewed as too dirty to use for the highlyprecise business of semiconductor manufacturing.
