Recently, Ningxia Yin and the annual output of 1.8 million 8-inch semiconductor silicon polishing sheet projects with a total investment of 3 billion yuan and a phase of investment of 1.5 billion yuan were put into operation in the western district of Yinchuan Economic and Technological Development Zone. The project has filled the gap in mass production of 8-inch silicon polishing wafers in China, breaking the monopoly of foreign companies on the Chinese semiconductor wafer material market. Semiconductor wafer technology has been monopolized by countries such as Japan, South Korea, and the United States. Silver and 8-inch semiconductor silicon polishing wafer projects have been successfully put into production, which can compensate for the domestic demand for 8-inch and 12-inch semiconductor-grade monocrystalline silicon wafers in the semiconductor integrated circuit industry and in the automotive, computer, consumer electronics, communications, industrial, medical and other industries. China relies on the import of high-quality semiconductor wafers to supply high-quality semiconductor wafers, significantly reduce costs and increase industrial competitiveness, and fully meet the urgent requirements of China's integrated circuit industry for silicon substrate materials.
Next, Ningxia Yinhe Semiconductor Technology Co., Ltd. will invest 6 billion yuan to launch an annual production of 3.6 million 8-inch semiconductor silicon polishing wafer projects and an annual production of 2.4 million 12-inch semiconductor silicon polishing wafer projects, through the development of high-quality semiconductor wafers The R&D and industrialization development has built an internationally advanced 8-inch and 12-inch semiconductor wafer industrialization, innovation research and development base.
In recent years, Yinchuan Economic and Technological Development Zone has accelerated the development of equipment manufacturing, new energy, new materials and other industries as pillar industries. It has introduced a number of new material industry projects that have significant influence at home and abroad, and built world-renowned monocrystalline silicon production. The base and the largest industrial sapphire production base in China are becoming important strategic new material production bases in China.
