What are the uses of quartz in semiconductors/photovoltaics?

Quartz, primarily composed of silicon dioxide, is characterized by high purity, high temperature resistance, corrosion resistance, good thermal stability, and minimal reaction with silicon. It is an irreplaceable key material in semiconductor and photovoltaic manufacturing. In the photovoltaic field, it is mainly used to make quartz crucibles to support and pull single-crystal silicon rods, ensuring that the silicon material is not contaminated during the high-temperature melting process. In the semiconductor field, it is processed into components such as quartz boats, quartz tubes, and quartz bell jars, widely used in diffusion, etching, and cleaning processes. It can withstand the ultra-high temperature environment of chip manufacturing while maintaining extremely high cleanliness, thus ensuring the performance and yield of chips and photovoltaic cells.
