Strategic cooperation supports the growing semiconductor and display manufacturing sectors
As semiconductor manufacturing and display technologies continue to advance, demand for ultra-high purity electronic chemicals is increasing alongside higher requirements for process stability and material quality. These specialty chemicals are widely used in wafer cleaning, photolithography, precision etching and other critical production steps where even trace impurities can affect manufacturing yield.
Against this backdrop, Zhe Jiang Realsunchem Co., Ltd., South Korea's Dongjin Semichem Co., Ltd. and Kum Suk Chemical Co., Ltd. signed a joint venture agreement in Shanghai on July 6 to establish a company specializing in the sales of ultra-high purity electronic chemicals.
The new venture combines Dongjin Semichem's experience in semiconductor materials, Realsunchem's manufacturing and market presence in China, and Kum Suk Chemical's expertise in high-purity specialty chemicals. Rather than serving as a conventional sales operation, the company is expected to become a dedicated platform connecting international technologies with local market demand across China's semiconductor and display industries.
The agreement comes as chipmakers and panel manufacturers continue investing in advanced production capacity, creating new opportunities for suppliers capable of providing reliable electronic chemicals, technical support and responsive local services. By bringing together complementary resources, the three partners aim to improve supply efficiency while supporting the long-term development of China's electronic materials ecosystem.
Rising Demand for High-Purity Process Chemicals
The formation of the joint venture reflects broader changes across the semiconductor supply chain. As chip manufacturing moves toward smaller process nodes and more advanced packaging technologies, production environments require tighter contamination control and greater consistency from every material used during fabrication.
Ultra-high purity electronic chemicals are essential in a wide range of manufacturing processes, including wafer cleaning, photoresist development, wet etching and surface preparation. The performance of these chemicals directly influences process stability, defect control and production yield, making quality and supply reliability increasingly important for semiconductor manufacturers.
Demand is also expanding beyond integrated circuits. New investments in OLED, Mini LED and other advanced display technologies continue to increase the need for high-performance electronic chemicals that meet stringent purity standards while supporting efficient, high-volume production.
For material suppliers, customers are no longer looking only for qualified products. They also expect stable supply, local technical support and the ability to respond quickly to changing production requirements. These market expectations have encouraged closer cooperation between international technology providers and manufacturers with established operations in China.
By combining global expertise with localized service capabilities, the new joint venture is positioned to provide more responsive support for semiconductor and display manufacturers while contributing to the continued development of China's electronic materials industry.
Combining Complementary Strengths for a More Responsive Supply Chain
Rather than focusing on a single product line, the joint venture has been established to integrate resources across technology, manufacturing and customer support. Each partner brings capabilities that address different stages of the electronic materials value chain, creating a more comprehensive service platform for semiconductor and display manufacturers.
Dongjin Semichem contributes extensive experience in electronic materials developed for semiconductor and display applications, together with long-term technical expertise in high-purity process chemicals. Liansheng Chemical strengthens the partnership through its manufacturing capabilities, local production resources and established customer network in China. Kum Suk Chemical complements the venture with specialized know-how in high-purity specialty chemicals and application development.
This combination enables the new company to respond more efficiently to customer requirements while supporting stable product supply, technical collaboration and faster market delivery. Instead of operating solely as a distributor, the joint venture is expected to provide closer cooperation throughout product selection, application support and supply chain coordination.
For semiconductor manufacturers, reliable material supply is increasingly linked to production continuity and process consistency. By bringing together international technology and localized operational resources, the three companies aim to improve service responsiveness and strengthen long-term partnerships with customers operating in China's rapidly evolving semiconductor and display sectors.
As demand for advanced electronic materials continues to diversify, collaboration between technology providers and regional manufacturing partners is becoming an increasingly common approach to improving supply resilience and supporting sustainable industry growth.
Supporting the Next Stage of Electronic Materials Development
The establishment of the joint venture comes as semiconductor and display manufacturers continue to place greater emphasis on supply reliability, material consistency and closer technical collaboration with chemical suppliers. As production technologies become increasingly sophisticated, electronic chemicals are no longer viewed as standard consumables but as critical process materials that directly influence manufacturing performance.
For suppliers, success is increasingly determined by more than production capacity alone. Technical expertise, localized customer support and the ability to respond quickly to changing manufacturing requirements have become equally important in serving high-end semiconductor and display customers.
The new company is expected to strengthen cooperation with downstream manufacturers by providing a dedicated platform for technical communication, product application support and market development. Through the integration of international technology and local operational resources, the joint venture aims to improve customer responsiveness while supporting a more stable and efficient electronic materials supply chain.
As investment continues across semiconductor fabrication, advanced packaging and next-generation display manufacturing, demand for high-purity process chemicals is expected to remain strong. Against this backdrop, the collaboration between Dongjin Semichem, Realsunchem and Kum Suk Chemical represents a practical step toward expanding the availability of ultra-high purity electronic chemicals for advanced manufacturing applications in China.
The signing of the joint venture agreement marks the beginning of a long-term collaboration built on complementary expertise, shared resources and a common commitment to supporting the sustainable development of the semiconductor and display industries.
