In high-tech manufacturing such as semiconductors and FPDs, contamination control is a critical factor determining product yield and reliability. The Clean Material Research Institute, the R&D center of Seoul Semitech Co., Ltd., leverages its expertise in high-purity processing and contamination control to R&D advanced clean materials and Personal Protective Equipment (PPE) for ultra-clean environment industries, including semiconductors, displays, pharmaceuticals, and bio-safety. Since successfully commercializing Korea’s first CF-707 non-woven wiper, the institute has led innovation in cleanroom supplies, developing COOLOVE (eczema-relief gloves), high-purity cleanroom masks, and high-performance garments for advanced 2nm nodes. For the bio-pharmaceutical sector, we develop high-reliability products for bio-production lines and sterilization processes, focusing on microbial/particulate control, surface cleanliness, and materials compatible with both sterile and non-sterile GMP Grade environments. Building on our core technologies, we are expanding into high-value PPE categories such as chemical-resistant suits, films, and gloves. As a "Total Clean & Protection Solution Provider" merging contamination control with personal protection, the Clean Material Research Institute is committed to developing next-generation solutions that meet ultra-fine process requirements and EU GMP Annex 1 standards.
