CMC Materials built its franchise around highly engineered consumables used in critical semiconductor process steps. Its core business lines included chemical mechanical planarization (CMP) slurries, CMP pads, electronic chemicals, and related materials technologies. These products are used to polish, clean, and control wafer surfaces during the fabrication of smaller, faster, and more complex semiconductor devices. The company also expanded through acquisitions, including International Test Solutions in 2021, which broadened its exposure to semiconductor test consumables.
