Quartz is a mineral composed of silicon dioxide, with the chemical formula SiO2. Pure quartz is colorless and transparent, but can appear in various colors due to trace amounts of pigment ions, finely dispersed inclusions, or the presence of color centers, which reduces its transparency. It has a vitreous luster and a greasy sheen on the fracture. Quartz products are widely used in semiconductor manufacturing, and high-purity quartz products are important consumables in wafer production.
The manufacturing process for quartz products is very complex. Quartz sand is first melted and smelted into quartz ingots, which are then heat-formed and cold-processed into quartz products. Based on the process and processing technology, quartz products can be divided into two types: fire-processed and machine-processed. Fire-processing is primarily used in the photovoltaic industry and has lower profit margins. Machine processing relies on different methods and combinations to complete shaping and polishing, primarily producing high-value-added products that require high consistency and stability, and is often used in the semiconductor industry.
Quartz components used in semiconductors can generally be divided into high-temperature and low-temperature components, respectively used in high-temperature processes such as diffusion and oxidation, and low-temperature processes such as etching, packaging, photolithography, and cleaning. Quartz components used in high-temperature processes, as they must operate continuously for hours at temperatures exceeding 1,000 degrees Celsius, require high-temperature resistance, excellent thermal stability, and resistance to deformation. The presence of hydroxyl groups alters the bonding structure of silicon dioxide, the primary component of quartz products, thereby reducing the material's thermal stability and significantly diminishing its high-temperature resistance. Therefore, quartz components used in high-temperature processes require dehydroxylation. Furthermore, these components must exhibit corrosion resistance, excellent light transmittance, and low impurity content. Quartz components used in low-temperature processes, on the other hand, do not require high-temperature processing, so the hydroxyl content of the quartz material is not a requirement.
