Domestic computing chip "displacement movement", superimposed chip downward cycle, what effect will be produced, we do not know, the key is the United States official policy is unpredictable. After a seven-month delay, Nvidia CEO Jen-Hsun Huang suddenly made a whirlwind visit to his offices in Beijing, Shanghai and Shenzhen on January 20, only to fly to Taipei 48 hours later. Mr. Huang's trip sent mixed signals.
Many people think that China's chip manufacturing process is not good, indeed, the current domestic lithography machine can only reach 90nm accuracy, the best domestic chip foundrySmic's technology level is only between 28nm-14nm. However, chip manufacturers can find technologically advanced foundrings, such as Huawei's Kirin 970 and Apple's mobile phone chips are made by TSMC. From the chip manufacturing process itself, chip manufacturing belongs to the downstream of the industrial chain, and China and the United States are outsourced.
At the beginning of the implementation of chip supply in the United States, Bill Gates warned that this will only force the Chinese market to accelerate the pace of self-sufficiency, and the final loss will be the export-oriented U.S. semiconductor market. And our expert Professor Zhang Zhaozhong made a statement on the chip supplyThe expansion of 28nm chip production line in Nanjing, what is its purpose...1, TSMC's purpose is to seize low-end chips to obtain more profits TSMC technical strength needless to say, this time TSMC invested billions of dollars in Nanjing expansion 28nm chip production line, its purpose is to seize the low-end chip market, get more profits, because now the chip is in short supply, low-end chip demand is also very large, In order to seize the low-end market and obtain more profits is the most important purpose of their expansion of the production line.
2, TSMC decided to invest 28.7 billion US dollars to expand South ChinaThe chip production line in Beijing factory to increase the production capacity of 28nm chips to meet more customer needs. Although the 28nm process is not the most advanced, this investment by TSMC shows its recognition of the importance of meeting market demand. Smic's rapid expansion has also prompted TSMC to strengthen its own capacity building to maintain its leadership position in the global chipmaking market. 3, previously, in order to curb the rise of SMIC, TSMC can only invest heavily in the expansion of 28nm chip production line in Nanjing. In short, TSMC chairman Liu Deyin once said: It seems that the supply of 28nm chips exceeds the demand, but it is realGlobally, production capacity exceeds demand. 4, TSMC invested billions of dollars in the expansion of 28nm chip production line in Nanjing, the reason why the location will be chosen in Nanjing, mainly because Nanjing as a first-tier city, can attract a large number of talents to work here, so that it can largely solve the problem of employment. Nanjing is a city with many excellent schools, which train talents to help chip manufacturing, solve technical problems and production problems.

On May 3, Qilu reported: According to the general manager of Zibo New Henghui Electronics Co., LTD., in July 2019, Zibo New Henghui Electronics invested 60 million yuan to recruit more than 20 top chip packaging experts from home and abroad for independent research and development.
The self-developed graphics card brought by now has once again broken the monopoly of Western technology. Although the exposure is only 1GB graphics card, Huawei will move towards 8GB mainstream high-end graphics card in the future. Huawei is not only a mobile phone company, but also an all-round technology company. With HuaweiThe level of domestic science and technology will maintain a high level. Because of Huawei, Chinese technology can stay vibrant. The most critical thing is that just recently, the first "pure domestic" chip came out, 100% self-developed without U.S. technology, completely breaking the U.S. monopoly! This chip refers to the newly released Longson 3A5000 processor, and its birth marks a new milestone of domestic chips, saying goodbye to foreign technology and realizing true autonomy.
According to the process of chip manufacturing, the IGBT industry can be divided into chip design, wafer manufacturing, module packaging andTest three sessions. However, IGBT chips compared to the manufacturing process and equipment of mobile phone chips, the requirements are not so high. In addition, different power levels of IGBT chips, there are also different sizes. In general, the higher the power level, the larger the chip size will be. Currently the most competitive lines for IGBT products are 8 inch and 12 inch.
year, "Longson 3" was successfully developed, 82-year-old Huang Lingyi proved that China's chip technology to a higher level, very well opened China's chip market, so that China saved several trillion yuan to buy chips from abroad money,At the same time, the birth of "Longson 3" also gives China's high-speed rail, Beidou navigation and other escort, let domestic technology become a barrier to protect the motherland, get rid of Europe and the United States and other developed countries in chip to our country.
1, domestic companies actively introduce talents China 28nm chip complete industry chain , government support China 28nm chip complete industry chain chip manufacturers from TSMC to introduce 100 engineers and managers, showing that China 28nm chip complete industry chain talent reserve enhancement. In the key field of 28nm lithography equipment, Shanghai Microelectronics' domestic 28nm lithography machine is expected to be delivered within the year, marking an important breakthrough in the industry chain at this node. 2, China's chip self-sufficiency rate is currently only 30%, the goal is to reach 70% by 2025. Despite the challenges, our country integratesCircuit industry sales revenue continued to grow, showing the resilience of the industry. Therefore, Ni Guangnan believes that the short board of 7nm May have an impact in specific areas in the short term, but the overall 14nm and 28nm technology is enough to support the country's infrastructure construction and development. 3, at present, China's chip self-sufficiency rate is only 30%, the goal is to increase to 70% by 2025. Despite the challenges, industry sales revenue continued to grow between 2019 and 2020, showing the strong momentum of the chip industry. Therefore, although the bottleneck impact of 7nm in the short term is obvious, the domestic chip industry is still in the long runThere is enough room for development to meet market needs.
4, SMIC also achieved 28nm mass production, the existing technology and equipment can support 28nm continuous production line. Secondly, the domestic market has a strong demand for 28nm, which can provide an order advantage. Demand determines the market, 7nm, 5nm of course there are smart phones, PC market demand, but the future sustainable development of smart cars, the Internet of things and other industries demand chips are almost 28nm.
5, lithography machine (0%), although the current domestic lithography machine localization is almost 0, but Shanghai Microelectronics hasThrough the energy production of 90nm process, 28nm lithography machine has made progress. However, lithography machine is the most difficult technology equipment in the semiconductor industry chain, and to reach the 7nm process, EUV lithography machine must be used, in terms of current Chinese technology, the next few years can break through this technical difficulty is very good.
6, China's domestic chips can now reach the process level of 90 nm. In the key links of chip manufacturing, equipment and materials such as lithography machine, etching machine, wafer, photoresist occupy an important proportion. In particular, lithography equipment, Shanghai microelectronics enterprises have been able to provide 90 nm levelThe product of... However, in the field of high-end KrF and ArF photoresist, the self-sufficiency rate of domestic products is almost zero, and it is heavily dependent on imports.
1, it is a domestic chip. This shows that our chip has been far ahead of the world, it is really a very proud thing. 2, Recently, China Beidou spokesman Ran Chengqi solemnly announced at the press conference of the State New Office that the Beidou system 28nm process chip has been mass produced, 22nm process chipAbout to mass production, ahead of the United States GPS two generations of technology. It is reported that the domestic Beidou navigation chip developer is Hunan Guoke Microelectronics Co., LTD., after Guoke Micro's "own core" was also recently held at the 2020 World Semiconductor Conference won the China Semiconductor Innovative products and Technology Award. 3, in the first two generations of satellites, most of the chips are imported from the United States, not only expensive, but also can not get the latest chips. In addition, the United States has placed restrictions on our country in many places, so that only a few years ago our military weapons could only be located by GPS. The year 2018 was an extraordinary year for the development of the BDSThis year. 4, the double star formed the Beidou navigation satellite test system, making China the third country with an autonomous satellite navigation system in the world after the United States and Russia, breaking the passive situation of relying on foreign navigation and positioning technology. It has greatly promoted the construction of China's spatial information infrastructure, made important contributions to national defense construction and national economic construction, and played an irreplaceable role in the rescue of Wenchuan earthquake in 2008.
