Cmc Materials Inc's Business Segments

Cabot Microelectronics Corporation, which was incorporated in the state of Delaware in 1999, is the leading supplier of high-performance polishing slurries and second largest supplier of polishing pads used in the manufacture of advanced integrated circuit (IC) devices within the semiconductor industry, in a process called chemical mechanical planarization (CMP). CMP is a polishing process used by IC device manufacturers to planarize or flatten many of the multiple layers of material that are deposited upon silicon wafers in the production of advanced ICs. Our products play a critical role in the production of advanced semiconductor devices, helping to enable our customers to produce smaller, faster and more complex IC devices with fewer defects. Our mission is to create value by delivering high-performing and innovative solutions that solve our customers challenges.
