Enabling Purity at the Nanoscale: Semiconductor Filtration SolutionsIn semiconductor manufacturing, we are on the battlefield at the molecular level. Chip manufacturing processes have entered the nanoscale era, with linewidths as small as a few nanometers. At this scale, even a microscopic particle invisible to the naked eye, or an ionic impurity, can cause circuit defects on the entire wafer, resulting in enormous economic losses. Therefore, ultrapure chemicals, ultrapure water, and ultra-clean gases are no longer auxiliary conditions, but rather the lifeline determining yield and performance. Filtration and separation technologies are the core gatekeepers protecting this lifeline.Our ultra-high purity materials precisely serve the core purification process in chip manufacturing:Ultrapure Water Filtration System:Application Scenarios: UPW polishing mixed beds in the final stages of chip rinsing and chemical dilution.Specific Products: PFA/PVDF monofilament screens, serving as the support framework and filtration layer for the filter element.Function: Effectively intercepts resin fragments and tiny particles detached from upstream, ensuring that the ultrapure water flowing into the wafer surface achieves PPT-level purity.High-Purity Chemical Solution Filtration:Application Scenarios: Terminal filtration of critical process liquids such as etching solutions, CMP slurries, and photolithography developers.Specific Products: High-precision PFA monofilament screens and seamless woven filter cloth.Function: Precisely filters gels, agglomerates, and metal ion contaminants in chemical solutions, preventing them from causing defects on the wafer surface and ensuring uniformity of etching and polishing.

Upholding Purity, Ensuring Safety: Filtration for Food & PharmaIn the food, beverage, and pharmaceutical industries, the core mission of filtration and separation technology goes far beyond "purification." It directly relates to the safety, taste, purity, and stability of the final product. Regulatory agencies in various countries (such as the FDA and EMA) have established extremely stringent standards for production processes and materials that come into contact with products. Failure in any filtration stage—whether due to microbial growth, the introduction of foreign matter, or contamination from filter media leaching—can lead to the scrapping of an entire batch of products, causing huge commercial losses and a crisis of brand reputation.
