In the semiconductor industry, quartz is widely used, and high-purity quartz products are an important consumable in wafer production. High-purity quartz glass products must be used for quartz components such as crucibles, crystal boats, and diffusion furnace core tubes that produce silicon single crystals. The main target market of quartz components in the semiconductor field is the diffusion and etching process in wafer foundry, which can be divided into two categories: high temperature region devices and low temperature region devices. The main devices that will be used are as follows:1. The devices in the high temperature area are mainly furnace tubes, glass boat frames, etc. used in diffusion oxidation and other links, which need to be in direct or indirect contact with silicon wafers in a high temperature environment; mainly fused silica glass materials are purchased and produced by thermal processing;
2. The devices in the low temperature area are mainly quartz rings in the etching process, as well as flower baskets and cleaning tanks in the cleaning process, which are mainly used in low temperature environments; mainly purchase gas refining quartz glass materials and produce them through cold processing.
Among them, the consumption rate of devices in the high temperature area is faster, but it is similar to a multi-chip machine (one carrier holds multiple silicon wafers), and the consumption rate of devices in the low temperature area is slower, but the single chip microcomputer (one carrier holds one silicon wafer); therefore both The overall market size is relatively close.
