Don’t eat fish to support technology:
The ban on Huawei is not an accident, because what the United States wants is the monopoly advantage of chips, so that it can maintain its dominant position in technology for a long time! From chip design to manufacturing and production, we have absolute core technology. The emergence of Huawei has completely broken Qualcomm's monopoly on the market. This is "fair competition" that they do not allow...
...The consequences of this will only make China self-sufficient.
Microsoft founder Bill Gates said this in an interview about the ban on sanctions against Huawei.
One of the top priorities in core-making, the basic semiconductor material silicon wafer, is a wafer made from silicon crystal pillars cut with a diamond blade. The larger the size, the more difficult it is to produce. Although domestic demand is huge, it has long relied on imports, and large-size technology is monopolized by Japanese companies. At present, domestic technology has been mastered for small-sized mass production, and the self-production rate of large-sized 8-inch and 12-inch products is still very low.
New progress: Shanghai’s newly upgraded 12-inch silicon wafer technology has been verified by SMIC. Although the production capacity is low, this is the rise of domestic silicon wafer manufacturers!
What is even more difficult is the photolithography process, which is where Huawei stumbles! The latest NA EUV lithography technology is preparing to enter the 3nm process, but SMIC has been unable to introduce EUV lithography machines. Although the power consumption of the breakthrough N+1 process can be close to 7nm, the performance cannot be reached, and 7nm cannot Mass production, let alone the development of 5nm... TSMC and SMIC are also subject to US technology constraints, and the only high-end lithography machine in the world is ASML... Therefore, when 7nm is opened, it should also be the time when 3nm is commercialized. Huawei Kirin is expected to Forced to become a next-generation product...
"Stuck in the neck" is the "encouragement" to force efforts!
While closely following the international pace, domestic core manufacturing is also making breakthroughs in exploring new directions! ——Graphene technology can be said to have started simultaneously around the world. Under the increasingly sophisticated manufacturing process, silicon wafers will eventually reach their physical limits. It is understood that the ultimate point may be 1nm. Even if it can be produced, the yield rate must be taken into consideration! Graphene’s carbon-based wafers are hailed as the next replacement for chip materials—domestic 8-inch graphene wafers have achieved small batch production!
Graphene is known as the thinnest among countless nanomaterials, reaching 0.335 nanometers! How thin? It’s one 200,000th of a human hair. It’s unbelievable that humans have discovered how thin it is. So since you’ve discovered it, you have to use it!
How to make chips from graphene? Can it reach the level of silicon wafers, because Kirin 9000 is packed with 15.3 billion transistors!
It is reported that the chip performance using graphene carbon-based wafers will be more than 10 times that of silicon-based chips, and more importantly, the power consumption will be lower - improving performance while reducing heat generation is exactly what mobile phones need The ultimate pursuit...
The speculation in the process is that 28nm carbon-based chips can reach the level of 7nm silicon-based chips, which is two generations of technology closer, while domestic mature processes can reach 14nm... That is to say, the 5nm level can be achieved without using an extreme ultraviolet lithography machine, which will also significantly reduce manufacturing costs!
Graphene material is so amazing. It is reported that its electrical conductivity is 100 times stronger than silicon, and its thermal conductivity is 10 times higher than copper. Its advantages...are enough to show that it is a very potential semiconductor material. But why hasn’t it been widely used yet? Because: expensive! ——It is reported that its price is as high as 5,000 yuan/gram!
But price is definitely not a hindrance to progress. The key lies in technology. The current level of graphene purification still has many impurities, so it is not yet mass-produced like silicon crystal pillars, but domestically produced 8-inch graphene The successful trial production of wafers also represents a successful breakthrough, which is completely enough to serve as an advanced sign of domestic technology!
And according to statistics on research in the field of graphene, domestic R&D has 37,521 patents, accounting for 67% of the world and ranking first in the world!
Exploring new areas, from passive to active. Mastering a core technology will gain the right to speak in a field. Having technological advantages can invalidate the so-called ban. Only by strengthening self-research capabilities can we no longer be led by the nose - since we cannot obtain the technology that others can use to their full potential. , then explore new technologies and use them to their full potential!
