Semiconductor Manufacture

What makes graphite the material of choice in the semiconductor industry? It has the required electrical and thermal properties. Graphite can withstand temperature recycling from room temperature to 1420 °C, maintaining strength at these high temperatures. Graphite combines availability, machinability and life of parts that can't be matched by other materials.


Advanced Graphite Materials

Requiring high purity from the graphite material and high standards of excellence in machining, GrafTech materials for the semiconductor area offer solutions for a broad number of market areas. We offer both extruded and isomolded materials developed for this market. Typical applications include:


  • Silicon crystal growth (Czochralski method)
  • Silicon carbide crystal and wafter production
  • Quartz processing and manufacture
  • Fiber optics
  • Polysilicon production
  • High purity machined graphite components
