High-Purity Quartz Square Tanks Launched for Semiconductor-Mia

The quartz square groove is integrally processed from high-purity quartz glass. The SiO₂ purity is high, offering excellent chemical stability, resistance to strong acids and oxidants, and is not prone to the precipitation of metal ions. This ensures that the wafers and optical samples are not at risk of secondary contamination during cleaning, etching, and soaking processes. Additionally, the thermal expansion coefficient is extremely low, enabling it to withstand rapid cooling and heating, and is suitable for high-temperature acid washing and constant-temperature soaking conditions. The product has excellent light transmission performance in the ultraviolet-visible light band, and can be directly used in spectroscopy detection and photochemical reaction testing scenarios.

Compared to the irregular-shaped quartz containers, the square structure is arranged in a regular pattern and has a high space utilization rate. It is convenient for the batch placement of multiple wafers and substrates, and is suitable for wet bench cleaning lines, tube furnaces for pre-treatment, and sample aging tests, etc. The product supports non-standard customization, allowing for the adjustment of internal dimensions, wall thickness, openings, flanges, chamfers, and the polishing or sanding treatment of the inner wall. The inner wall can be treated with polishing or sanding, and strict control is implemented to manage surface defects such as spots, scratches, and bubbles. The product undergoes clean cleaning and quality inspection before leaving the factory, meeting the strict requirements of various fields such as semiconductor pilot production, photovoltaic cell processing, physical and chemical analysis, and biochemical research.
