/PRZWT/Recently, Zhongding Liansheng Technology Co., LTD. (hereinafter referred to as "Zhongding Liansheng"), a high-tech enterprise specializing in the research and development of high-end ultrapure water systems for the semiconductor industry, officially signed a contract to join the Qizhaozhi Science and Technology Innovation Platform, taking a crucial step in deepening technological innovation in semiconductor ultrapure water equipment and expanding industrial ecosystem cooperation. As a national high-tech enterprise, Zhongding Liansheng has been deeply engaged in the field of semiconductor ultra-pure water equipment for 13 years, continuously focusing on the core demand for "high-precision water for advanced processes of 14nm and below". Currently, it has become a core supplier in the domestic high-end ultra-pure water system niche market for semiconductors. In 2024, the domestic market share of the company's leading product, "High-End Ultra-Pure Water System for Semiconductor Industry", exceeded 10%, ranking among the top in domestic similar enterprises and providing core support for the localization of key water-using equipment for the semiconductor industry.
Focusing on high-end ultrapure water equipment, we build a moat of technology and quality
Zhongding Liansheng was established in 2011, rooted in the core area of the "Integrated Circuit and Special Equipment Cluster", and has always been dedicated to the research and development, production and service of high-end ultra-pure water systems for the semiconductor industry. The product provides highly stable water supply for advanced semiconductor manufacturing processes such as photolithography, etching, and thin film deposition by precisely controlling water quality resistivity (stable ≥18.24MΩ · cm) and particle content (≥0.1μm ≤1 piece /mL). It is a key equipment supplier in the upstream of the semiconductor manufacturing industry chain. The company has now passed the ISO9001 quality management system certification. With strict quality control and technical strength, it has been successively awarded honors such as "National High-tech Enterprise" and "Jiangsu Province Innovative Small and Medium-sized Enterprise", setting a quality benchmark in the field of semiconductor ultra-pure water equipment.
In terms of technological breakthroughs, Zhongding Liansheng has achieved breakthroughs around three core goals: "precise water quality control, dynamic adaptation to multiple processes, and stability under extreme working conditions". Firstly, it has developed a coupling technology of "high-precision water quality sensing + machine vision particle recognition" to capture micro-particles in water in real time, ensuring long-term stability of resistivity and solving the pain point of fluctuating water usage parameters in multiple process sections. Second, a "preparation-transportation-monitoring closed-loop system + adaptive pipeline" was constructed, combined with PLC intelligent control algorithms. The response time for multi-process switching is less than 5 seconds, which is compatible with advanced processes of 14nm and below, and has overcome the problem of dynamic adaptation lag in traditional systems. Thirdly, the development of "dynamic filtration regulation + inert gas protection chamber" was carried out, optimizing the fin structure of the heat exchanger. The frosting rate under low-temperature conditions was reduced by 90%, effectively solving the problem of insufficient long-term water quality stability. Moreover, the accuracy of temperature and humidity coordinated control far exceeded the industry average.
The collaborative efforts of industry, academia and research institutions are accelerating the transformation of scientific and technological achievements and domestic substitution
To continuously strengthen its technological barriers, Zhongding Liansheng has deepened its cooperation among industry, academia and research. Relying on its enterprise R&D center, it has established a close collaborative mechanism with Suzhou University of Science and Technology to jointly carry out the "Design and Development of High-End Ultra-Pure Water Systems for the Semiconductor Industry" project. Suzhou University of Science and Technology has developed a high-precision water quality sensing integrated module and an adaptive delivery pipeline to ensure stable parameters. By adopting machine vision, laser recognition and a closed-loop system, the fluctuation of water usage is addressed. Zhongding Liansheng focuses on the mass production and transformation of core modules, quickly putting the water quality sensing modules and adaptive conveying components jointly developed into production, achieving efficient transformation of technology into products.
Relying on technological innovation, Zhongding Liansheng has successfully broken the market dominance pattern of international giants such as Kurita Kogyo of Japan (ULTRA PURE series). The company's products have reached the international advanced level in key indicators such as water quality stability and multi-process adaptability, while the procurement cost is only 70% to 80% of that of imported equipment, significantly reducing the R&D and production costs of domestic semiconductor enterprises. Up to now, the core technologies of Zhongding Liansheng have been transformed into 30 intellectual property rights, including 2 invention patents, 16 utility model patents and 12 software Copyrights. All intellectual property rights have been deeply applied to core products. The company has now become the "preferred domestic alternative solution" for leading semiconductor enterprises such as Xiamen Yuntian, filling the technological gap of independent control of high-end ultra-pure water systems for 14nm and below processes in China.
Join hands with Qizhouzhi to lead the transformation and upgrading of the industry through technological innovation
As semiconductor manufacturing processes evolve towards 7nm and more advanced nodes, the core procedures have increasingly strict requirements for the purity and stability of ultrapure water. To accelerate digital transformation and enhance the capacity for scientific and technological innovation and the transformation of achievements, Zhongding Liansheng has signed a contract to join the Qizhouzhi Science and Technology Innovation Platform.
In this collaboration, Zhongding Liansheng will rely on the "resource connection + technology empowerment" solution of the science and technology innovation space to precisely connect university experts with innovative achievements in the semiconductor industry, break through the innovation chain of "core module research and development - complete machine testing - mass production adaptation", and accelerate the implementation of new technologies such as multi-stress coupling regulation and digital twin water quality monitoring. At the same time, by leveraging the platform's industrial chain map and dynamic bidding and tendering functions, we will deeply explore potential customers and high-quality suppliers in the core areas of the semiconductor industry such as the Yangtze River Delta and the Pearl River Delta, enhance the company's customer acquisition efficiency, and further expand market share and brand influence.
Looking ahead, Zhongding Liansheng will continue to focus on the core technology field of high-end ultra-pure water systems in the semiconductor industry, with a focus on expanding new scenarios such as 7nm process water adaptation and ultra-pure water treatment in the hydrofluoric acid system, and promoting the upgrade of equipment in three major directions: "higher purity, faster response, and lower carbon consumption". Meanwhile, the company will leverage its dual advantages in technology and market to provide high-quality and cost-effective water equipment for downstream semiconductor enterprises, promoting the transformation of the semiconductor industry towards high-end and autonomy, and helping China's semiconductor ultra-pure water equipment occupy a core position in global competition.
