Beijing Kehua Microelectronics Materials Co., Ltd. is a Sino-US joint venture established in 2004. It is a supplier of photoresists and supporting reagents covering KrF (248nm), I-line, G-line, and UV broad spectrum. Together with service providers, it is also a high-tech enterprise with independent intellectual property rights that integrates the research, production and sales of advanced photoresist products. Kehua Microelectronics has a mid-to-high-end photoresist production base, with 100-ton cyclized rubber-based UV negative photoresist and 1,000-ton negative photoresist supporting reagent production lines, G/I line positive photoresist production line (500 Tons/year) and positive glue supporting reagent production line (1000 tons/year), 100-ton 248nm photoresist production line. Kehua Microelectronics photoresist product sequence is complete, and the product application areas cover integrated circuits (IC), light-emitting diodes (LED), discrete devices, advanced packaging, micro-electromechanical systems (MEMS), etc. Product types cover KrF (248nm), G/I line (including broad spectrum), mainly including: KrF photoresist DK1080, DK2000, DK3000 series; gi line photoresist KMP C5000, KMP C7000, KMP C8000, KMP EP3100 series and KMP EP3200A series; negative glue KMP E3000 series used in Lift-off process; BN and BP series used in discrete devices. Kehua Microelectronics has strong R&D technical strength, has many photoresist experts, and has strong photolithographic collagen material synthesis, formulation and related basic evaluation capabilities; it can continue to launch new products that meet customer needs; Kehua Microelectronics has been established since its establishment Since then, it has undertaken a number of national and Beijing-level key photoresist research and development and industrialization projects. Kehua Microelectronics has a complete analysis and application test platform that supports product development and factory inspection. The company has two mini FABs with a resolution of 0. 11um ASML PAS5500/850 scanning exposure machine, Nikon step exposure machine, TEL ACT8 coating and developing all-in-one machine and Hitachi S9220 CD SEM and other mainstream equipment. The above-mentioned test platform ensures that Kehua can carry out the development and comprehensive evaluation of KrF, G/I line photoresist products and key raw materials. Kehua Microelectronics has a complete management system, including four systems: quality management system (ISO9001), environmental management system (ISO14001), occupational health and safety management system (ISO45001) and hazardous substance process management system (IECQ QC080000).
