Cabot Microelectronics Corporation
Cabot Microelectronics Corporation was a leading supplier of CMP slurries and pads for semiconductor manufacturing, acquired by Merck KGaA in 2022.
Cabot Microelectronics Corporation
Cabot Microelectronics Corporation was founded in 1999 as a spin-off from Cabot Corporation, focusing on CMP consumables used in semiconductor fabrication. The company's core product line — polishing slurries and pads — served every major chipmaker, including TSMC, Intel, and Samsung, giving it a dominant position in a specialized materials market. The company invested heavily in R&D to maintain technical leadership, with over 500 patents globally. Its strategy revolved around developing advanced formulations for emerging chip nodes, such as those used in logic and memory devices. The geographic footprint spanned North America, Asia, and Europe, with manufacturing sites in the US, Japan, and South Korea. Cabot Microelectronics employed approximately 1,500 people at its peak and generated annual revenues exceeding $1 billion. In 2022, Merck KGaA completed its acquisition of the firm for approximately $1.7 billion, integrating it into Merck's electronic materials division. This transaction marked a significant consolidation in the semiconductor materials supply chain. A structural differentiator was Cabot Microelectronics' exclusive focus on a single process step in chipmaking — CMP — which created both vulnerability to industry cycles and deep expertise that competitors struggled to replicate. The firm's research-driven approach and proprietary chemistry positioned it as a critical supplier in an industry with high barriers to entry.
