- Business
- 3S KOREA Co., Ltd. is a South Korea-based technology manufacturing company that specializes in the development and production of semiconductor wafer transport carriers and industrial environmental test systems. Founded in January 1991 and headquartered in Seoul, South Korea, the company operates across two primary business divisions: the High-Tech Materials Division and the Environmental Test Equipment Division. As the first and only domestic enterprise in South Korea to commercialize 300mm wafer carrier containers, 3S KOREA serves semiconductor manufacturers, electronic component producers, automotive suppliers, and heating, ventilation, and air conditioning (HVAC) equipment developers globally. The company provides an extensive portfolio of precision products and industrial testing solutions organized into key categories: semiconductor wafer carriers, including 300mm Front Opening Shipping Boxes (FOSB) designed for secure, contamination-free transport of silicon wafers between wafer fabrication facilities; Front Opening Unified Pods (FOUP) engineered for automated micro-environment wafer handling within cleanroom production lines; Panel Level Package (PLP) FOUPs for advanced semiconductor packaging; customized wafer cassettes; environmental test equipment, including psychrometric calorimeters and balanced ambient room calorimeters used to measure the thermal capacity and energy efficiency of residential, commercial, and automotive air conditioning systems; compressor performance test benches; air-to-air heat exchanger testing systems; environmental chambers for extreme temperature, humidity, and climate simulation; specialized testing facilities, including anechoic chambers and acoustic measurement rooms; and secondary battery testing systems and factory automation logistics equipment. 3S KOREA conducts manufacturing and research operations primarily at its production plants located in Anseong, Gyeonggi-do, South Korea, while maintaining international commercial and technical operations through entities such as its subsidiary Shanghai 3S HVAC Technology Co., Ltd. and its regional joint venture Suzhou 3S Semiconductor Materials Co., Ltd. in China. The company supplies critical components and systems to leading semiconductor foundries, integrated device manufacturers, and global industrial clients across South Korea, China, and wider Asian and international markets. In recent developments, 3S KOREA has executed several strategic expansions and corporate reorganizations to enhance manufacturing capacity and strengthen its presence in high-growth markets. In January 2025, the company committed an investment of 61.1 billion South Korean won to build a new manufacturing facility at the Anseong 5th General Industrial Complex, scheduled for completion by 2027, aimed at scaling output for 300mm wafer carriers and expanding production of electric vehicle secondary battery test equipment. In February 2025, its Chinese affiliate, Suzhou 3S Semiconductor Materials Co., Ltd., secured exclusive strategic investment funding from China's Chuxin Fund to expand local supply capabilities of 12-inch wafer carriers and accelerate advanced process research and development for regional semiconductor fabricators. In late 2024, the company secured a key patent in China for its advanced Panel Level Package (PLP) FOUP technology, reinforcing intellectual property protections for next-generation packaging applications. Additionally, in September 2026, 3S KOREA initiated a corporate capital restructuring via a stock consolidation plan to increase the par value of its common shares from 500 won to 2,500 won, aimed at stabilizing share price dynamics and optimizing market liquidity.
