Monocrystalline silicon rods are the raw materials for making chips. At present, China's 8-inch single-crystal silicon rods are imported by 90%. The 12-inch single-crystal silicon rods are monopolized by foreign countries and rely entirely on imports. It is exciting that they are located in the new station of Hefei City. The Anhui Xinyi Semiconductor Co., Ltd. of the High-tech Zone independently developed a 12-inch monocrystalline silicon rod for eight years, filling the gap in the domestic integrated circuit industry. Not only that, Anhui Yixin developed large-sized silicon rods after slicing, grinding and more than 40 channels. After the process, the formed silicon wafers have reached the international advanced level, achieving the “zero breakthrough” of 12-inch electronic grade single-crystal silicon wafers and filling the domestic gap.
Eight 12-inch single-crystal silicon furnaces are in operation at Anhui Yixin's monocrystalline silicon rod production plant. Although this workshop does not seem to be large, it is currently the largest domestic 12-inch single crystal silicon rod manufacturing base. The core technology of these devices is also independently developed by Anhui core, which also broke the international monopoly.
Large-sized single-crystal silicon rods and single crystal furnaces, as raw materials and manufacturing equipment, belong to the upstream of the integrated circuit industrial chain, and play a supporting role for the entire industry. They have always been the weak link in the integrated circuit industry in China. Reporters from the new station high-tech The district learned that Anhui Yixin has made breakthroughs in these two major technical problems, which also means that China's integrated circuit industry has made rapid progress.
In recent years, Hefei has always been guided by technological innovation, and has firmly grasped the opportunities of strategic emerging industries, focused on key issues, focused on resources, and strived to make the integrated circuit industry a core industry that enhances the overall competitiveness of our city. Currently, our city It has 129 IC companies, including 102 design companies, 3 manufacturing companies, 8 packaging and testing companies, and 16 equipment and materials companies.
Today, the leading companies in the IC industry in Hefei continue to gather together. The top five global foundry companies, Jingjing Science and Technology, domestic and international design industry leaders, MediaTek, Qunlian Electronics, Zhaoyi Innovation, Junzheng Technology and other companies have settled down. Hefei, which has five companies with sales revenue exceeding 100 million yuan.
In the field of panel driver ICs, Piertech has also gathered in China, and has set up a company in the north, Zhongdian Jingxian, Hongjing, and Longxun. In the field of home appliance chips, it has gathered companies such as Junzheng Technology, Silicon Lijie, etc. Also in storage, automotive. Electronics, power chips and other fields also have some corporate layouts. Hefei has become one of the fastest-growing and most successful cities in China's integrated circuit industry, and has become a rising star in the domestic integrated circuit industry.
