1, improve the degree of autonomy and security from the perspective of national and technological independent innovation. Research and development is indispensable. For example: before the Loongson was not produced, Chinese computer chips were foreign brands, when the self-developed Loongson came out, the national security agencies would not choose foreign chips, only their own production is the most secure.
2, and self-developed ISP chipRelatively speaking, it is not so complicated, it does not need to involve so many technical levels, and it is naturally a better choice to start from the ISP chip. Mobile phone manufacturers self-developed ISP chips, the entry is relatively simple, but also easy to let users feel the benefits of self-developed chips, such investment can produce returns at a relatively fast speed, but also in the configuration of homogenization to take out unique advantages, increase the chips in the high-end market, for the high-end mobile phone market is particularly important.
3, the profit of the chip from the chip design. Not chip manufacturing. The manufacturing shortage is temporary. Man made it himself. It can't last.
I think the real intention of this agreement is to monopolize and suppress the development of science and technology in our country. However, China's scientific research system reflects the overall status quo of bad money driving out good money, and the chip industry is particularly outstanding, eager for quick success and quick success, rushing forward, harming the country and the people. 5, that is to say, the two core links of chip manufacturing "wafer and seal test", are concentrated in North America or new, horse, and the only domestic production capacity also needs to take care of consumer electronics and other products, therefore, the shortage of automotive chips, may cause an industry opportunity is "automotive chips need to be localized",'> How hard is it to develop chips?1, the most advanced EUV lithography technology in particular tests the wisdom of developers. Extreme ultraviolet light (EUV) has a wavelength of only 15nm, but the process limit to be reached is between 3 and 7nm.
2, not to mention the most difficult design, from the basic manufacturing, it is also a challenge for us. Manufacturing has become a problem mainly because some developed countries, especially the United States, have implemented technology blockades in some high-precision manufacturing fields, limiting the export of the most advanced manufacturing processes and design concepts to our country, and what we can buy is some technologies that have been eliminated. Therefore, our low-end chip industry can still have its own development opportunities.
3, let's briefly talk about where the chip manufacturing is difficult, first of all, as long as the chip is mentioned, we have to mention the Dutch Asmel company. The company is the world's largest chip designer and equipment manufacturer. The Hisilicon Kirin chip used in Huawei mobile phones that we are familiar with was redesigned and improved after Huawei purchased the architecture from Asmail, and the equipment used to manufacture the chip is the lithography machine that we are familiar with.
4, the second is that the difficulty of eliminating errors is too large, the size of the chip is small, but there are aboveHundreds of millions of transistors, can be measured at most a few hundred signal lines, the number is not proportional, to infer which transistor design error, it is even more difficult.
5, compared with the PC chip, the chip difficulty on the car is huge, in addition to the need to control costs, energy consumption, and so on. In the end, even if we develop a chip that meets the specifications of the car, this will be the ticket to get in. The research and development cycle of the automotive industry generally reaches about 2 years, which cannot support such a long cycle for many small businesses.
1, chip design Chip research and development : According to the architecture design chip research and development , Xiaomi engineers began to carry out specific chip design work. This process includes circuit design, layout, simulation and so on. Chip manufacturing: After the design is completed, Xiaomi sends the design file of the chip to the chip foundry. Foundries manufacture and package chips according to design documents. Chip testing: After manufacturing, Xiaomi conducts rigorous testing and verification of the chip.
2, chip development, such asThe process of creating a piece of technological art is delicate and challenging. First of all, the specification definition is the blueprint for creation, which requires a deep understanding of market needs and precise setting of the functions and performance of the chip. This involves not only evaluating the feasibility of the technology, but also considering multiple dimensions such as cost, power consumption, security and robustness.
3. In the back-chip test stage, the wafer cp test verifies the perfect combination of the packaged circuit, the FT test verifies the stability of the function, and the ESD test ensures the safety of the chip. The reliability test and test, like the ultimate acceptance of the work, every link is related to the chip performanceWhether to win praise and trust in the market. Every step is crucial, every step is full of challenges.
4, then is the most important part of the production of chips lithography. The use of some special chemicals, so that it will be exposed to ultraviolet light will dissolve, to get the chip development we need shape. Then, by using an etching machine to implant ions on the exposed silicon, the corresponding P and N semiconductors are formed, and the above process is repeated to make a three-dimensional structure.
"Stuck neck" is the "encouragement" to force efforts! While closely following the international pace, domestic core making is also moving towards explorationBreakthrough in a new direction! -- Graphene technology can be said to have started at the same time around the world.
On the one hand, the huge market size of the chip market has attracted the attention of Internet manufacturers, and the current "lack of core tide" and "jam neck" threat, Internet manufacturers have to build cores. On the other hand, the development of the chip industry chain is becoming more and more mature, and the cost of core making is reduced, and the deep development of cloud computing and other businesses is inseparable from the blessing of chips. Throughout the Internet, people with names are not "making core", or on the way to "making core".
From this trend can be seen, unless BYD such a "solid work.There are more and more core making enterprises, otherwise, after the number of new energy vehicles continues to rise in the future, IGBT chips will also have a lack of core "explosion". Self-driving chips: There will be no shortage, but it is still limited to people. In the view of most consumers, autonomous driving and electric vehicles complement each other and are indispensable.
1, the research chip category majors include electronic science and technology, microelectronics science and engineering, integrated circuit design and integrated system, electronic information science and technology, etc. Electronic science and technologyThis major is a comprehensive major, involving physics, information technology, computer and other aspects of knowledge. Graduates can be engaged in telecommunications companies, mobile companies, electronics-related research institutes, research and development of electronic components and production and operation management of electronic enterprises.
2, the most related to chip design, there are three undergraduate majors: electronic science and technology, electronic information science and technology, microelectronics science and engineering. The most relevant is microelectronics science and engineering. Do chip design, without a graduate degree, it is very, very difficult, so you can choose "integrated circuit design" or "Integrated Circuit Design" at the graduate level"Microelectronics and solid-state Electronics".
3, want to develop chips, the major categories are electronic science and technology, microelectronics science and engineering, integrated circuit design and integrated system, electronic information science and technology, computer science and technology. Subdivision directions include microelectronics technology, MEMS, integrated circuit design, etc. Chip is a general term for semiconductor component products, and the core technology involved is integrated circuit technology, so microelectronics and other related majors have become key majors in the development of chips.
