Kayex develops and manufactures crystal growing equipment for the semiconductor and photovoltaic (solar) materials industry.

Kayex serves these industries by supplying production equipment for single crystal materials such as:

• silicon
• germanium
• gallium arsenide

These materials are produced in our Kayex HAMCO and FX (formerly Ferrofluidics) high yield crystal growing furnaces. The crystals are later sliced into thin wafers and often polished. The wafers become the starting materials for semiconducting devices such as integrated circuits, discrete devices, and photovoltaic (solar) cells.

Kayex produces a family of high-temperature crystal growing furnaces utilizing the Czochralski, or CZ, method, in which the highly pure material is melted, and a seed crystal is dipped into the molten material and made to grow. The crystal increases in size as the seed is slowly raised from the melt. Thus the crystal growing furnace is often called a "crystal puller."

High quality, production-ready, fairly priced crystal growing products and superior after sale service have become hallmarks of our success. But another attribute stands out: the ability to uniquely engineer our products to exacting requirements while protecting proprietary customer technology. Our wide range of products and leadership position are largely attributable to our continuing research and development programs.

Kayex is uniquely positioned to serve the expanding Asian wafer industry with our manufacturing joint venture operation, Kayex Zheda, in Hangzhou, China. Since 1997, our partner, the Zhejiang University Machine Factory, has enabled Kayex Zheda to supply the Chinese market with premium quality Kayex crystal pullers, and enabled Kayex to supply the world with cost-competitive equipment.
