Semiconductor Crystal Growth

Specialty graphite plays a critical role in the hot zone of semiconductor crystal growth processes due to its exceptional thermal stability at ultra-high temperatures, uniform thermal conductivity, and outstanding corrosion resistance. Whether in the Physical Vapor Transport (PVT) method for SiC, the Czochralski (CZ) method for monocrystalline silicon, or the Heat Exchanger Method (HEM) for sapphire, these processes all take place under extreme temperatures and chemically aggressive environments, making specialty graphite an indispensable material.

Graphite parts for silicon crystal growth

Silicon crystals for semiconductor applications are grown on an industrial scale by either the CZ or the Float Zone method. While Float Zone furnaces usually have no or very few graphite parts in them, the CZ method relies heavily on high purity graphite parts and graphite felt insulation. SGL Carbon has a long-standing history of collaboration with the global leading silicon crystal growth companies. We offer the right materials for graphite and CFRC susceptors, heaters, reflectors, tubes, rigid and soft insulation felts and others.

Graphite materials for silicon carbide crystal growth

The growth of SiC single crystals usually involves some kind of physical vapor transport mechanism at very high temperatures in excess of 2400 °C. The graphite materials offered by SGL Carbon are better fitted to work in these extreme environments than any other materials on the market. No matter what your furnace specifics are, if you are looking for SiC powder production as a raw material or at growing SiC boules: SGL Carbon has the right materials for you and can assist in finding the perfect solution.
