About Us
Collaborating China and Korea, driving innovation to become a world-class semiconductor materials supplier.
Company Profile
Zhejiang Huachuan Semiconductor Materials Co., Ltd. was established in 2025 and is a Sino-Korean joint venture with a total investment of 3 billion RMB. Located at Longxin Smart Industrial Park, Tangya Town, Jinhua City, Zhejiang Province, the company enjoys a prime location and comprehensive industrial support.
Korean shareholder Seong Hyun Technology brings over 30 years of industry experience. By combining technology transfer with independent innovation, Huachuan Semiconductor is committed to providing customers with high-quality core semiconductor consumables.
Our core products include silicon rings and silicon electrodes, widely used in wafer etching processes. With superior product quality and professional technical support, we have established long-term partnerships with numerous leading domestic and international semiconductor companies.
Core Advantages
Sino-Korean Joint Venture with Leading Technology
The company is a Sino-Korean joint venture that deeply integrates the strengths of both nations' semiconductor industries. The Korean shareholder has decades of expertise in silicon components for semiconductor etching processes. Its flagship product, the high-end CSR silicon ring, has long served as a core component supplier for industry giants such as Samsung and SK Hynix, leveraging world-class technology and market channels. The Chinese partner leverages local research and industrial resources to establish a solid foundation for material R&D and commercial deployment. This strategic alliance enabled Huachuan Semiconductor to rapidly connect with the high-end supply chain from its inception.
Core technologies are independently developed and fully under our control
From ultra-high-purity silicon raw materials to precision finished products, we maintain full-chain technical control and in-house production to ensure product quality and supply security from the source.
Nanometer-level precision manufacturing
The product uses ultra-high-purity silicon. Each silicon ring features over 1,000 precisely drilled micro-holes distributed uniformly. A single precision inspection unit costs as much as 200 ten thousand yuan. From fine-tuning CNC equipment to rigorous multi-stage inspections, every step is executed with uncompromising excellence.
Fill the gap in domestic substitution
High-end gate rings and similar products will effectively fill domestic technology and supply gaps, break through "chokehold" bottlenecks, and play a critical strategic role in safeguarding the security of China's semiconductor supply chain.
Location and Industrial Ecosystem Advantages
Located in the Loongson Smart Industrial Park and adjacent to the Jinyihu Lake Science & Technology Innovation Ecosystem, the area is home to a cluster of high-tech enterprises including new energy vehicles and robotics, with a well-developed industrial ecosystem. The park has attracted over 40 quality information technology innovation companies, forming a complete industry chain that spans chip R&D, system integration, and full-device manufacturing.
