Japan Chemical Industries' Indium Tin Substrate Depends on High-Purity Red Phosphorus
Only two companies worldwide produce high-purity red phosphorus, used in indium tin substrate for data centers.
The indium tin substrate, which supports internal light communication in data centers, relies on high-purity red phosphorus as its raw material.
Only two companies worldwide can produce this high-purity red phosphorus, including Japan Chemical Industries.
The company’s Fukushima Second Factory, visited in September, spans 150,000 square meters with five buildings.
