1, in the June 9 2021 World Semiconductor Congress, Chinese Academy of Engineering, Wu Hanming, elaborated on the three core challenges of chip manufacturing in the post-Moore era, which is both a challenge and an opportunity for China. First, the fundamental challenge: precision graphics. When the wavelength is larger than the physical size, the resolution can be extremely fuzzy.
2, from the distribution of the core technology of artificial intelligence enterprises, big data and cloud computing accounted for the highest proportion of 413%, followed by hardware, machine learning and recommendation, and service robotics. Intelligent chips accounted for only 38%.
3, China's chip manufacturing capacity is still insufficient, semiconductor equipment investment will speed up Wu Hanming, academician of the Chinese Academy of Engineering, said on the 17th, the current development of China's chip manufacturing capacity is seriously lagging behind the demand for supply capacity and demand gap is getting bigger and bigger.
4, the forum first by Wu Hanming academician made "after Moore era chip manufacturing challenges and opportunities" theme report.
Chip At present, China's chip is not only the manufacturing process or chip mass production are relatively backward, the current chip Huawei has made 5nm chip, China's other companies have not reached this level, most stay in 14nm. The United States, Japan and South Korea have broken through 2 to 3 nanometres, and even to 1 nanometer breakthrough.
No one is willing to take over the research and development work on semiconductors. These factors together, resulting in China's semiconductor technology is not only a difficult start, and the development is not as rapid as the advanced countries in the West, so China's chip industry will be presented in such a situation that the United States and other countries stuck in the neck.
Manufacturing has become a problem mainly because some developed countries, especially the United States, in some high-precision manufacturing areas to implement the technology embargo, to limit the export of the most advanced manufacturing processes and design concepts to our country, we can buy, are some of the technology has been eliminated. So our low-end and mid-range chip industry can still have a chance to develop on its own.
But the development of our country in the field of chips, is far from being able to compare with the Western countries, although the level of quality of domestic chips is also more and more stable, but if you look at the overall perspective, and the gap between the Western countries and the Western countries is not half a star.
2, China's chip manufacturing process level At present, China's chip manufacturing process level has reached 14nm, this level can meet the needs of most application scenarios. And in the future, China's chip manufacturing process will be further enhanced, is expected to 2025, China's chip manufacturing process will reach 7nm.
3, nm. According to query Baidu encyclopaedia information shows that China as of September 25, 2023 can produce 14 nm chips, mass production rate of 95 per cent. chip is a kind of electronic components, manufactured by microelectronics technology, the circuit and system integration in a tiny silicon chip.
4, China's domestic chip can reach 90 nanometres. Domestic chip level can only achieve 90nm. From the chip manufacturing link, photolithography, etching machine, wafer, photoresist and other equipment and materials account for a large proportion. One of the photolithography equipment, the current Shanghai Microelectronics is 90 nanometres.
5, China's photolithography now reaches 22 nanometres. Before Shanghai Microelectronics technology breakthrough and megastar, China's domestic photolithography has been stuck in can only manufacture 90nm process chip. This time China directly from 90nm breakthrough to 22nm also means that China has achieved localisation in some key core areas of lithography.
2. Once again, the domestic 5G chip performs better when the signal is weak, and maintains a more stable signal connection when moving at high speed. In addition, domestic 5G chips also have excellent support for multi-frequency and multi-mode, which makes them well suited to a variety of different scenarios.
3, G high-end chips can promote the digital economy and industrial upgrading. With the large-scale commercialisation of 5G technology, many traditional fields will face huge transformation and upgrading challenges, and the digital economy will get a bigger boost. In this process, 5G chips will play an important role in supporting and driving industrial innovation and digital transformation.
4, G technology application scenarios: 5G to help the rise of the industrial Internet Industrial Internet, as a new generation of information technology and the deep integration of the industrial economy to form the emerging industry and application mode, is to achieve the key foundation of the digital transformation of industry.
The development of the chip industry is very stable, at present the world's various chip enterprises are very good: the chip industry belongs to the high-tech industry, in this industry, a large part of the enterprise benefits are very good.
This view is certainly untenable. If a country does not have scientific and technological strength, then it will have no say in the world. In today's internationalised world, comprehensive national power is the power that every country pursues and develops. If a country's comprehensive national strength waits to improve, then the country will be surpassed by other countries.
The three statements, although each has its own merits, are common in one point, that is, the cycle of doubling is 18 months, as for doubling (or quadrupling) is the number of circuits integrated on the integrated circuit chip, is the performance of the whole computer, or the performance that can be bought by a dollar is a matter of opinion.
