Wei Shaojun, chairman of the Integrated Circuit Design Branch of China Semiconductor Industry Association, said today that with the closure of chip design enterprises in China by external advanced processing resources, the manufacturing technologies that can be used by chip design enterprises in China are no longer as rich as before, and it is necessary to pay attention to the design technology that does not depend on advanced technology in technological innovation. Among them, there are two technical paths worth exploring. One is the innovation of architecture, which has been suggested by the industry that it is the golden age of computer architecture innovation. The second is micro-system integration, and the three-dimensional integration technology evolved from packaging technology is gradually moving towards the foreground. (Reporter Guo Hui)

The first demonstration in China! Seiko Technology's high-performance PAN fiber technology has made key progress, and Seiko Technology's high-performance fiber precursor (polymerization process) "The first demonstration of safety and reliability of chemical process used in China" has successfully passed the evaluation of the expert group, which indicates that Seiko Technology's carbon fiber precursor preparation technology can be applied to industrialization on a large scale. On December 7th, Zhejiang Petroleum and Chemical Industry Association, entrusted by Zhejiang Emergency Management Department, organized and held the review meeting of "Demonstration of Safety and Reliability of Chemical Process Used for the First time in China" for high-performance PAN fiber in Hangzhou. Seiko Technology received a reply letter on December 10th.The concept of consumer electronics fluctuated higher than the daily limit of Tianjian and Yingtong Communication, while Tianjian and Yingtong Communication fluctuated higher than the daily limit. Zhongke Lanxun rose more than 8%, followed by Rambler, Guoguang Electric, hivi Technology and Zhuoyi Technology.Shanxi Securities: The launch of new OpenAI products catalyzes the demand for low-orbit satellite to continue to accelerate. Shanxi Securities Research Report pointed out that 1) The "Open AI 12 Days" activity was held, and the official version of o1 &pro and the full version of ChatGPT pro o1 were released faster and more powerful than o1 preview, and they performed better in code, mathematics and writing, and still possessed the original ability of picture reasoning. With the marginal cost of training continuing to increase and cot reasoning computing power continuing to increase, the computing power demand in 2025 is real and may continue to exceed expectations. It is suggested that the current optical module, copper connection, power supply and liquid cooling should be switched to the low valuation of 2025 performance. 2) Amazon shows trn1 ultra cabinet products, and cloud manufacturer ASIC brings incremental demand for copper connection. Cloud manufacturers' self-developed ASIC will bring important demand increment for high-speed copper connection. At present, copper connection system component manufacturers are concentrated overseas, while bare wire supporting capacity is concentrated in China. 3) Last week, Yuanxin Qian Fan's third networking satellite was successfully launched in Taiyuan, and SpaceX mobile phones were directly connected to satellite networking for commercial use. The development of LEO satellite Internet is related to 6G standard discourse right, orbital frequency resources and the game of international air and space infrastructure powers, which is expected to force the launch of LEO constellation in China to accelerate again. Under the catalysis of continuous events, the relevant targets of the industrial chain are expected to usher in a certain performance contribution and drive the double-click market.
