in the chip field for many years. Huawei HiSilicon, , Ziguang Group, SMIC and Yangtze River Storage have helped China’s chip growth and improved the self-service of my country’s domestic chip supply chain system. This is not the same, because these semiconductor companies are all based on traditional silicon technology research and development.
Moore's law is about to expire?
The traditional material is silicon as the raw material. The highest purity silicon material is extracted from sand, and the silicon is made into wafers wafers, which are then sent to the wafer manufacturing plant to be processed into chip integrated circuits. Finally, after a series of packaging and testing , etc., the chip is mounted on the electronic device. This is the life of a chip.
In other words, the source of these processes is silicon, but now the advanced silicon technology is in the hands of foreign companies, lithography machine , materials and parts, etc., we all rely on foreign companies , Which makes it impossible to leave foreign technology on a global scale and in my country’s industrial chain. If silicon is not used, then it is necessary to look for chip manufacturing materials again. If this is the case, can it reshape the industrial chain? Doesn't contain the opponent's technology at all.
graphene wafer chip
For example, the Chinese Academy of Sciences broke through the key technology of graphene some time ago. Graphene, as a material for manufacturing chips, can be processed into carbon-based chips. In theory, it is equivalent The process performance is ten times stronger than traditional silicon-based chips. At present, the Chinese Academy of Sciences has broken through key technologies and successfully unveiled an eight-inch graphene wafer. This is definitely great news for us.
We all know that traditional silicon chip development is strictly in accordance with Moore’s Law.Today, the most advanced process chip is the 5 nano chip produced by TSMC, and 3 nanometers and 2 nanometers are also under continuous development, which means that the development law of chips has been infinitely close to the limit of Moore's Law. So after Moore's Law reaches its limit, where the chip will go will become a question.
and now silicon-based chips require lithography machines to manufacture, 5 nanometer chips require extreme ultraviolet light, which is what we call EUV lithography machines to be able to manufacture, and it is also an advanced process Chips, the greater the demand for lithography machines, but with the level of domestic lithography machines, it is still more difficult to reach the level of EUV. It takes decades or even more time to complete the complete localization task in the field of lithography machine. It must be known that it took decades to develop this EUV lithography machine in foreign countries.
If it is said that decades of time have been spent on the lithography machine, in the end it is still unable to develop such an EUV lithography machine, then it will be a huge loss for us. But now, graphene and wafers have brought us some hope. This kind of graphene wafer does not have too many requirements for the lithography machine. In the future, the outside world believes that it is a chip that can be manufactured without a lithography machine.
Can a chip be made without a lithography machine?
However, looking at the nature of the current chip market, it is still more difficult to manufacture chips without the lithography machine. But if carbon-based chips can achieve theoretically ten times the performance of silicon-level chips of the same process, then chips made by DUV lithography machines can replace those made by EUV.
We can still make certain breakthroughs in the DUV lithography machine. In more than ten years of development, we are not without our own achievements, so that from 2020 to now China core There are frequent good news from the film, and the good news from the Chinese Academy of Sciences this time is very exciting.
In addition to the Chinese Academy of Sciences,There are also many good news that are worthy of excitement. For example, Tianshuzhi Chip has self-developed 7-nanometer GPGPU training chip, Han's Laser self-developed lithography machine has been sold in small batches, West Lake University has developed three-dimensional micro-nano processing technology for ice engraving, and Huawei HiSilicon self-developed GB independent display chip and so on.
All this proves that Chinese chips are making continuous progress. Even in the field of lithography machines, the Academy of Duty Fees has already announced its entry into the game. If we can really use this graphene wafer chip in the future to get rid of the shackles of foreign lithography machines, then in the future development, we will surely be able to get a head start. The chip industry has developed for decades, and there has always been something worthy of our study in technology, and China's chips have been developing in the direction of self-research. Even with the dangers ahead of us, we believe that with the existence of these excellent domestic enterprises, we can solve even the biggest problems. The Chinese Academy of Sciences can be said to be our biggest hero this time.
