In the core link of the semiconductor industry chain, 12 inch silicon wafers serve as the "foundation" for chip manufacturing, and their technological breakthroughs and supply capabilities are directly related to the development foundation of the global electronic information industry. On this track of sustained global demand explosion, Chinese manufacturers are accelerating their breakthrough, and the listing of Xi'an Yicai is an important milestone in this process. Mr. Wang Dongsheng, the founder of the company, once founded and led BOE to achieve a leap from scratch, from catching up to standing at the forefront of the global display industry, and has been committed to solving the core problem of "chip shortage and screen shortage" in China. After stepping down from BOE, as a continuation of the journey of "chip", Wang Dongsheng will lead Xi'an Yicai to continue to cultivate in the semiconductor materials field with years of deep accumulation and strategic vision in the high-end manufacturing field, striving to build an innovative enterprise with international competitiveness and promote the independent development and technological breakthroughs of China's key scientific and technological materials. During the growth process of the company, Mr. Liu Yiqian, Chairman of Guohua Life Insurance and founder of "Dragon Art Museum", has provided continuous trust and support since the early days of the company, injecting solid capital power into its development. The combination of technology and capital has laid a dual foundation for the steady development of Xi'an Yicai. On October 28th, Xi'an Yisiwei Material Technology Co., Ltd. (referred to as "Xi'an Yicai") was successfully listed on the Shanghai Stock Exchange with the stock code "688783". As a leading domestic manufacturer in the field of 12 inch silicon wafers and the first non-profit enterprise to be accepted after the release of the "Science and Technology Eight Measures", Xi'an Yicai's successful listing not only injects new momentum into the company's development, but also fully demonstrates the firm support of the capital market for high-quality non-profit technology-based enterprises with key core technologies, huge market potential, and outstanding scientific and technological innovation attributes.

According to the prospectus, this domestic company, which ranks first in both the shipment volume and production capacity of 12 inch silicon wafers, has achieved a leapfrog growth in revenue from 1.055 billion yuan to 2.121 billion yuan in the past three years, with a compound annual growth rate of about 42%. With the competitive barriers built by core technologies such as crystal pulling, molding, and polishing, the product has entered the core supply chain of mainstream storage IDM factories and logic wafer foundries in China.
