Entegris is stepping up its push into the fast-growing AI semiconductor market, completing the acquisition of a specialist diamond materials manufacturer and striking a long-term development partnership with synthetic diamond leader Element Six to advance next-generation chip cooling technologies.
The two strategic moves mark a significant expansion by the Nasdaq-listed company into silicon carbide (SiC) and diamond-enabled thermal management materials for advanced AI packaging, as rising computing power puts unprecedented pressure on data centres to manage heat.
“Growth in AI compute, from model training to inference, is intensifying power and heat-management demands in data centers,” said Olivier Blachier, President, Materials Solution and SVP, Chief Innovation Officer at Entegris. “We are excited to announce that Entegris is entering this fast-growing market to bring necessary innovation to meet our customers’ chip and package level materials demands.”
The first major step is the completed acquisition of Advanced Abrasives Corporation, a New Jersey-based manufacturer of diamond-based precision super-abrasive consumables used in polishing hard substrates.
The acquisition strengthens Entegris' existing silicon carbide chemical mechanical planarization (CMP) portfolio, which includes slurries, pads, cleaning solutions and surface conditioning technologies. It also builds on the company's intellectual property in materials science and surface engineering.
Entegris plans to invest in a new manufacturing line in Taiwan to accelerate the commercialisation of its SiC solutions, following strong customer engagement. The company will also continue exploratory research and development in the United States focused on next-generation thermal interface materials.
In a parallel move, Entegris has entered into a long-term development partnership with Element Six, a global synthetic diamond leader and part of De Beers Group, to accelerate the integration of diamond-based thermal management technologies into advanced semiconductor packaging.
The collaboration will target scalable and cost-effective wafer-level and heterogeneous integration solutions. The focus will be on reducing manufacturing complexity, lowering thermal boundary resistance and meeting the increasingly demanding performance requirements of next-generation logic and memory chips, including 3-D integration.
The strategic expansion comes as thermal management emerges as a major bottleneck in semiconductor development, particularly as AI workloads drive higher power consumption and heat generation. Conventional heat-spreading materials are increasingly being challenged, creating opportunities for advanced materials and engineered thermal interfaces.
“Thermal management is emerging as a critical industry challenge. We believe the move from conventional heat-spreading materials to novel materials and engineered thermal interfaces will mark a major shift in semiconductor manufacturing,” said Blachier. “Our goal is to facilitate better heat dissipation without compromising performance or reliability. We’re helping customers make that transition through materials innovation and integration at scale.”
