Last year Colorado-based Coorstek acquired Covalent materials, the spin off of Toshiba Ceramics in Japan, and as a result now provides GaN-on-Si epiwafers for power devices and integrated circuits (ICs) as well as aluminium nitride (AlN) substrates for hybrid circuits and engineered ceramic components for semiconductor processing equipment. These are being demonstrated for the first time at next week’s International Symposium on Power Semiconductor Devices and ICs (ISPSD) in Prague in the Czech Republic.

“The latest gallium nitride-on-silicon technology helps customers achieve higher device manufacturing yields and breakdown voltages based on lower defect densities and leakage current,” said Dr Jun Komiyama, R&D Manager at CoorsTek. “The shift from 150 mm to 200 mm diameter GaN-on-Si process is also improving the economics for power electronics in electric and hybrid automobiles, solar photovoltaic inverters, RF and microwave power, and more.”

The terms of the acquisition of the Philips ceramic operation in Uden were not disclosed, but the deal extends its footprint to a dozen European manufacturing locations in the Czech Republic, England, Finland, Germany, Italy, Netherlands, Norway, Scotland, and Sweden.

As a part of Philips, the Uden site supported its global lighting business. In addition to securing an exclusive, long-term agreement to supply Philips Lighting, CoorsTek will use the site to serve a broader set of customers and applications beyond lighting, including automotive, electronics, and medical. 

“The integration of Uden’s people, equipment, and technology into CoorsTek extends our regional presence and capabilities even further — a natural fit and complement to our advanced ceramics expertise,” said Timothy Coors, Co-CEO of CoorsTek.

“The Uden team will help support our expanding customer base across Europe and around the world,” said Andreas Schneider, Executive VP of CoorsTek in Lauf, Germany. “CoorsTek has known and respected Philips and Uden for decades. Combining Uden’s 60 years of engineering know-how and manufacturing capabilities with the ceramics expertise CoorsTek has developed over the past century — it is a great opportunity to push the frontiers of technology and help make the world measurably better.” Using advanced ceramic injection molding and automated volume manufacturing, Uden can produce millions of high-purity ceramic parts each year.
