Electronic poly-silicon manufacture
SIAMC's high-purity graphite seed chunk are widely used in the production of electronic-grade polysilicon using the Siemens process. The purity requirement of seed chunk is up to 5ppm. SIAMC's graphite meet this high purity requirement and provide excellent thermal stability and uniformity during the polysilicon growth process. Additionally, our graphite products can be tailored to meet specific customer requirements for shape, size, and purity, making them an ideal choice for semiconductor manufacturing.
