Semiconductor Chemicals Storage Tanks

Product core: Jiangsu RANA semiconductor chemical storage tank is made of semiconductor-grade high-purity modified PFA lining, produced in a 9000㎡PPB/PPT grade clean room. Through the hot pressing process, it achieves "zero leaching, zero pollution" bonding, and is specially designed for high-purity chemicals used in semiconductor manufacturing (such as copper etching liquid, stripping liquid).

Competitive Advantages: As a member of the China Semiconductor Industry Association, our products have been certified by SMIC and Taiwan, China Qiaoli Chemicals, demonstrating metal ion content ≤0.05ppb (industry standard 0.1ppb) and particle size ≤0.05μm (industry standard 0.1μm). Equipped with anti-static coatings (surface resistance ≤10^9Ω), they effectively prevent electrostatic adsorption of particles while ensuring dielectric purity.

Application scenarios: It is used in semiconductor wafer manufacturing (such as photoresist development, metal etching), packaging and testing, etc., such as copper etching liquid storage in chip factories, temporary storage of cleaning liquid in packaging and testing factories, etc., which can reduce chip defects caused by impurities (such as line width error from 5μm to 3μm), and help customers improve the yield of high-end chips.
