Chemical Mechanical Planarization (CMP) is a process used in the semiconductor industry to create a flat, smooth surface on a substrate. It is a combination of chemical and mechanical processes that use a slurry of abrasive particles suspended in a liquid to remove material from the substrate. The slurry is applied to the substrate and then a polishing pad is used to mechanically remove material. The process is used to create a planar surface on the substrate, which is necessary for the fabrication of integrated circuits. CMP is used in the production of a variety of semiconductor devices, including memory chips, microprocessors, and other integrated circuits. It is also used in the production of flat panel displays, optical components, and other microelectronic devices. The CMP market is highly competitive, with a number of companies offering products and services. Some of the companies in the CMP market include Applied Materials, Tokyo Electron, Lam Research, KLA-Tencor, Cabot Microelectronics, and Dow Chemical. Show Less Read more
