On May 23, Suzhou Jingrui Chemical Co., Ltd. (“Jingrui Shares”) was successfully listed on the ChiNext Board of the Shenzhen Stock Exchange, with stock code 300655.

As a standing director unit of the Strategic Alliance for Technological Innovation in the Integrated Circuit Materials and Components Industry, Jingrui Co., Ltd. focuses on the R&D, production, and sales of four major categories of microelectronic chemicals: ultra-pure high-purity reagents, photoresists, functional materials, and lithium-battery binders. Our products are widely used in five emerging industries—semiconductors, LEDs, flat-panel displays, lithium batteries, and photovoltaic solar energy—and are involved in various process steps such as cleaning, lithography, developing, etching, film removal, and slurry preparation for our customers’ products. The company is located in Suzhou City, Jiangsu Province, one of China’s most developed regions for the microelectronics industry. Leveraging the region’s industrial advantages, we remain diligent and steady in our approach, with customers spanning across China and our products exported to markets in Japan, South Korea, Southeast Asia, and other regions.

As one of the earliest companies in China to enter the field of microelectronic chemicals production, Jingrui Co., Ltd. has organically combined independent R&D with collaborative R&D in terms of technological processes, and has mastered a series of core technologies, including ion-exchange technology and distillation technology. Among these, ion-exchange technology can effectively remove metal ions and anions, while distillation technology can effectively control the overflow of micromolecular clusters. Meanwhile, the company ensures high precision and high efficiency in product manufacturing by implementing stringent quality controls across all stages—production, testing, packaging, and more.

The company’s ultra-pure, high-purity reagents all meet the G3 standard established by the Semiconductor Equipment and Materials International (SEMI). Among these, the company’s independently developed hydrogen peroxide has reached the highest purity level—G5—and has been successfully put into mass production, breaking the foreign technology monopoly. Relying on major national programs such as the “863” and “02” initiatives, the company has built China’s most advanced application testing platform for i-line and g-line photoresists. It has also been the first in China to achieve mass production of core photoresists widely used in current integrated circuit chip manufacturing, making it one of the largest photoresist manufacturers and sellers in China today.

As a high-tech enterprise in Jiangsu Province, the company owns a substantial portfolio of independent intellectual property rights, including 27 invention patents and 4 utility model patents. It has also drafted and promulgated 1 national standard, 3 national standards, and 15 industry standards. Several of its products have been recognized as provincial-level high-tech products, and its technological achievements have received numerous prestigious awards.

Driven by the continuous growth in downstream market demand, the company has earned recognition from its downstream customers thanks to its robust R&D capabilities and outstanding product advantages. As a result, it has successfully cultivated and maintained a large base of high-quality domestic and international clients, establishing a premier business platform that lays a solid foundation for the company’s sustained development. All of the company’s clients are leading enterprises in their respective fields. Successfully integrating into the supply chains of these top-tier clients is a testament to the company’s technological strength and also provides a strong customer base for its future growth. During the reporting period, the company’s key high-quality client resources included Youyan Semiconductor, JA Solar Technology, Sanan Optoelectronics, Chimei Innolux, Xinli, and HuaRun ShangHua, among others.

The semiconductor industry is the sector with the highest demand for ultra-pure, high-purity reagents. Our flagship product, hydrogen peroxide, has already been included in the supply-chain evaluation systems of several well-known domestic semiconductor manufacturers. Among them, HuaHong Macro has completed product evaluation, Wuhan Wuxin has entered the factory audit stage, and SMIC is currently conducting technical verification.
