Company Profile

Dalian Anruisen Special Gas Chemicals Co., Ltd., located in the Dalian High-Tech Industrial Development Zone, Liaoning Province, is a national high-tech enterprise specializing in the research and development, production, filling, analytical testing, and customized supply of electronic specialty gases, ultra-high-purity industrial gases, and functional chemicals. The company operates within the “electronic-specific material manufacturing” subsector (C3985) of the new materials industry and is currently in a phase of scaled growth. Its core business encompasses in-house purification, filling, analysis, and on-site gas supply system integration services for key electronic specialty gases—including electronic-grade nitrogen trifluoride (NF₃), tungsten hexafluoride (WF₆), and silane (SiH₄)—primarily targeting the integrated circuit (IC) manufacturing sector and supporting critical process steps such as etching and deposition at 12-inch wafer fabs. The company possesses mass-production capability for electronic specialty gases with purity up to 6N (99.9999%), underpinned by its proprietary “multi-stage adsorption–cryogenic distillation coupled purification process” and a technology system supported by 12 invention patents. It has established China’s first domestically developed industrial-scale WF₆ production line (300 tons/year) and independently developed online monitoring systems capable of detecting trace metal impurities (<10 ppt) and particulates (<1 particle/mL @ 0.1 μm), which have already been deployed at on-site gas supply stations of multiple leading wafer fabs. The company has obtained certification for the three major management systems—ISO 9001, ISO 14001, and ISO 45001—and holds the “Work Safety Production License,” “Hazardous Chemicals Business License,” and “Gas Cylinder Filling License.” Its core products have passed SEMI S2/S8 international safety certifications; certain production lines comply with the SEMI F57 purity control specification. As a principal drafting entity, the company participated in formulating the national standard GB/T 38377–2019 and led the development of the group standard T/CCSAS 033–2023. Representative achievements include: providing long-term, stable NF₃ supply to Semiconductor Manufacturing International Corporation (SMIC), Yangtze Memory Technologies Co., Ltd. (YMTC), and ChangXin Memory Technologies, Inc. (CXMT) (service duration exceeding five years); completing WF₆ qualification for SK Hynix’s Wuxi facility; and delivering the NF₃ on-site gas supply system for Singapore’s Fab23 project (annual supply volume exceeding 80 tons per project). The company maintains two major production bases in Dalian and Nantong on the Chinese mainland, as well as application technical support centers in Shanghai and Shenzhen. Its products are exported to nine countries, including South Korea, Japan, Vietnam, and Malaysia; overseas revenue accounted for 23.7% of total revenue in 2025. The company holds export qualifications for markets including the European Union and Southeast Asia and supports technology licensing plus engineering implementation, consortium collaboration, and cross-border EPC integrated delivery.
