Company information
The doujin industry provides various semiconductor materials and precision processing. We handle main products such as silicon, sapphire, SiC, GaN, quartz, alumina, and sintered SiC, and we have established a system that allows for integrated production from crystal growth to wafer processing in-house. In addition to standard semi-products, we also offer custom solutions, characterized by our flexibility in responding to requests regarding size, processing type, and quantity. We also handle crystal materials such as silicon, sapphire, SiC, GaN, LN, LT, quartz, GaAs, CaF2, MgF2, as well as consumables like quartz, fine ceramics, polishing materials, wafer cases, wire saw equipment, and diamond wires. The doujin industry is globally expanding its business from material procurement to processing. Strong support from overseas group companies, partner companies, and networks forms an important foundation of our capabilities. Through over 20 years of experience in trade between Japan, China, Korea, and Taiwan, we have built unique trade expertise and networks.
