Hubei Sinophorus Electronic Materials Co., Ltd.

Hubei Sinophorus Electronic Materials Co., Ltd. was established in November 2008 with a registered capital of 260 million yuan. It is a national high-tech enterprise specializing in the research and development, production, and sales of ultra-high purity electronic chemicals for semiconductors. The company is mainly engaged in the research and development, production, and sales of electronic chemicals. Its main products include general wet electronic chemicals such as electronic grade phosphoric acid and electronic grade sulfuric acid, as well as functional wet electronic chemicals such as etching solution, developer, cleaning agent, regenerator, and stripping solution. It is one of the earliest enterprises in China to engage in wet electronic chemical business. After more than ten years of continuous investment, technological accumulation, and market expansion, the company has successfully developed and mass-produced electronic grade phosphoric acid with the highest grade of G3 in SEMI C36-1121, electronic grade sulfuric acid with the highest grade of G5 in SEMI general standards, as well as 37 functional wet electronic chemicals in five categories including etching solution, cleaning agent, regenerating agent, developer, and stripping solution. It has also achieved batch supply to mainstream customers in the integrated circuit industry at home and abroad.

The company attaches great importance to technological innovation work and, with the joint guarantee of a mature R&D system, professional technical R&D team, and sufficient R&D investment, has mastered multiple core patents. In 2019, the company's key technology project for producing ultra-high purity electronic grade phosphoric acid and highly selective etching solution for chips was awarded the Second Prize of National Science and Technology Progress Award by the State Council. In 2022, the company's main products, electronic grade phosphoric acid and electronic grade sulfuric acid, were identified by an expert group organized by the China Electronic Materials Industry Association. The overall technology of these achievements has reached the international advanced level. In 2023, the sub project of the National Major Science and Technology Project (referred to as the "02 Project") for large-scale integrated circuit manufacturing equipment and complete processes undertaken by the company, "High Selective Tungsten Metal Removal Liquid," was accepted by the Major Special Management Center of the Ministry of Science and Technology. The independently developed high selective tungsten metal etching liquid product meets the demand for functional chemicals for advanced domestic storage chips.

In the future, Sinophorus Electronics will actively seize the strategic opportunities of chip localization, focus on the integrated circuit industry, and continue to carry out research and development in forward-looking technology and process improvement of wet electronic chemicals, new products of wet electronic chemicals, electronic special gas technology and products, waste liquid recovery, purification and reuse of wet electronic chemicals, precursor processes and materials for semiconductors, and auxiliary materials for wet electronic chemicals, continuously enriching product types and optimizing industrial layout, Continuing to deepen cooperation with domestic and foreign integrated circuit customers, actively exploring the global market, while promoting the localization of semiconductor materials, we will provide first-class products and services for global semiconductor customers. All employees will adhere to the values of "innovation, purity, and excellence", and are committed to building Sinophorus Electronics into a world-class electronic materials enterprise.
