High-purity graphite products, which have unique properties compared with metal materials and other ceramic materials, are used in a variety of industries, including semiconductors. In particular, our high-purity graphite materials, which contain less than 3 ppm of ash, are widely used in heaters and crucibles for pulling single crystal silicon and boats for liquid-phase epitaxial growth in the semiconductor manufacturing processes. In addition, CLEAR CARBON, composed of an SiC film coated on a high-purity graphite substrate, has earned a reputation for excellent quality worldwide as susceptors for epitaxial growth and other jigs.
