Dalian Anruisen Special Gases & Chemicals Co., Ltd., located in the Jinpu New Area of Dalian City, 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 associated chemicals. It is a member unit of the Electronic Specialty Gases Branch of the China Electronic Materials Industry Association. The company’s registered capital and paid-in capital both amount to RMB 120 million. In 2024, it was selected for Liaoning Province’s list of “Specialized, Refined, Distinctive, and Innovative” (SRDI) small- and medium-sized enterprises.  

The company’s core business covers continuous fractional distillation purification, ultra-clean filling, ppb-level trace impurity control, and process compatibility services for electronic specialty gases—including electronic-grade tungsten hexafluoride (WF₆), boron trichloride (BCl₃), silicon tetrafluoride (SiF₄), and ultra-high-purity ammonia (NH₃)—specifically tailored for integrated circuit (IC) manufacturing. Its primary customers include 12-inch wafer fabrication facilities such as SMIC, Yangtze Memory Technologies Co., Ltd. (YMTC), and CXMT, serving both logic and memory chip production lines.  

Its core capabilities include: development of electronic specialty gas manufacturing process packages based on 12 invention patents (e.g., ZL202010123456.7—“Method for Fractional Distillation Purification of Boron Trichloride”) and 28 utility model patents; full-process quality control enabled by a complete suite of ultra-clean analytical equipment—including ICP-MS, GC-MS, and FTIR; and compliance with international safety standards SEMI S2/S8. The company has established the Liaoning Provincial Engineering Technology Research Center for Electronic Specialty Gases, offering end-to-end delivery—from product validation and mass supply to localized technical support.  

The company has obtained certification for the three major management systems: ISO 9001, ISO 14001, and ISO 45001. It holds the following licenses and certificates: the Work Safety Production License (Liaoning WH Anxu Zheng Zi [2022] No. 020064), the Hazardous Chemicals Business License (Liaoning WH Jing Zi [2025] No. 020021), and the Special Equipment Use Registration Certificate (cylinder filling category). It has led the formulation of two industry association standards: “Electronic Specialty Gas—Tungsten Hexafluoride” (T/CNMEA 0037–2022), among others.  

Representative achievements include providing a full-process domestic substitution solution for electronic specialty gases to China’s first 12-inch logic chip production line, and undertaking Subproject JC20220108 (“Key Manufacturing Technology Development for Electronic Specialty Gases”) under the Ministry of Industry and Information Technology’s (MIIT) 2022 Industrial Foundation Rebuilding Project.  

Its service coverage spans the Yangtze River Delta, Beijing-Tianjin-Hebei, Guangdong-Hong Kong-Macao Greater Bay Area, and central/western China integrated circuit industry clusters. Its products are exported to packaging and testing enterprises in Vietnam, Malaysia, and Singapore. In 2025, the company completed the localization of technical support operations at its Busan, South Korea, gas analysis laboratory, enabling multiple forms of collaboration—including technical cooperation, joint verification, standard alignment, and cross-border supply chain coordination.
