Sintec distributing MTC’s PBN and CVD silicon carbide in Europe

Ceramic component maker Morgan Technical Ceramics (MTC), which is a division of UK-based Morgan Crucible Company plc, has entered into an exclusive European distribution agreement with Kennametal Sintec Keramik (UK) Ltd of Newport, UK. Since the beginning of March, Sintec has been distributing both MTC’s pyrolytic boron nitride (PBN) and CVD silicon carbide (SiC) materials for use in semiconductor manufacturing.

“We continually look at ways to improve our processes, and by working with Sintec we will be able to shorten lead times, meaning customers will receive products sooner,” says MTC’s general manager Phil McGraw. “Previously parts were shipped from our site in Hudson, USA, but Sintec has a local customer service organisation in the UK and Germany that is able to offer faster response times to our European customers.”

MTC says that PBN suits compound semiconductor manufacturing because it offers intrinsic purity, superior mechanical strength and thermal stability. It is a non-toxic, non-wetting material that does not react with acids, alkalis, organic solvents, molten metals or graphite. PBN also has bulk impurity levels of less than 100 parts per million, with metallic impurities of less than 10 parts per million. It also withstands high temperatures (1800°C in vacuum and 2000°C in nitrogen), without deformation, making it suitable for furnace components and melting vessels.

MTC’s Performance SiC is used for semiconductor processing equipment manufacturing and is available in two grades: ultrapure and low electrical resistivity. Using a chemical vapor deposition (CVD) manufacturing process, both ultrapure and low-electrical-resistivity Performance SiC outperform conventional materials in hostile chemical and plasma environments, it is claimed. Its high purity, stiffness, thermal shock resistance and thermal conductivity also suit a variety of demanding semiconductor processing applications, the firm adds.
