The semiconductor industry is a very large industrial chain.

Semiconductor materials are at the upstream of the entire semiconductor industry chain, among which wafer manufacturing materials include silicon wafers, photomask, photoresist, photoresist auxiliary materials, process chemicals, electronic specialty gases Polishing fluid and pads, targets, and other materials, including lead frames, packaging substrates, ceramic substrates, bonding wires, packaging materials, chip bonding materials, and other packaging materials,Each major category of materials includes dozens or even hundreds of specific products, and there are as many as hundreds of fine molecule industries.

Kousei Seimitsu's products and services mainly focus on the pre lithography processes such as cutting, grinding, and polishing of semiconductor material wafers.
