As the world's largest consumer market for electronic products, China is enough to provide a broad testing ground for chip technology. In this game, at the beginning, the United States wanted to control the export of advanced chip manufacturing equipment, thinking that in this way, wouldn't the development of our high-end chips be limited?
Americans originally thought that they could set limits everywhere with the trump card of chips in their hands, but what was the result?
We are stunned to get a high-end chip close to the 7nm level, and the technology is independent, and we have broken out of a way. The Americans were dumbfounded, and there were probably a hundred surprised expressions on their faces.
Since the design, foundry, and equipment restrictions of high-end chips, the unwilling Americans have turned their attention to high-performance AI chips and want to restrict exports. As a result, our scientific researchers are not vegetarians, and they have risen to the challenge and broken through technical barriers, such as Tai Chi of China's AI optical chips.
And the key is that we are making rapid progress in the production capacity of mature chips of 28 nanometers and above. At this time, the United States still wants to make a fuss about the chip IP instruction set?
According to a report by the Global Times on April 25, the Americans intend to "cut the knife" with the RISC-V instruction set.
Unexpectedly, our dragon architecture LoongArch has quietly caught up with the pace of X86 and ARM, which has made the wishful thinking of the United States fall through again.
Think that's the end of it?NO!
According to CCTV's public report on April 25, a team of experts from mainland China is developing the third generation of "glass perforation technology", replacing traditional silicon substrates with glass to achieve a big opportunity for overtaking in corners.
In other words, chips are to be made on glass.
The action is really fast, directly brewing to change lanes and overtake on the wafer substrate, if this happens, the impact will be great, and the silicon-based technology pattern for decades may have to be redefined by us.
Because in the case of the traditional chip technology path is limited, mainland technicians have proved in practice that it is possible to bypass the existing obstacles by exploring and adopting new materials, technologies and manufacturing methods, so as to catch up and surpass in the chip industry.
From the perspective of observed trends, such as the research and development of the third generation of "glass perforation technology", glass, as a chip substrate, can theoretically achieve more efficient heat dissipation and smaller volume, bringing fundamental changes to chip design and packaging.
This technology may allow chips to be fabricated on unconventional materials such as glass, which not only breaks the limitations of traditional silicon wafers, but also has the potential to bring cost-effectiveness and performance improvements.
In addition, the research and development of carbon-based chips and graphene chips is also regarded as an important way for the chip industry to "change lanes and overtake".
Unlike silicon-based chips, which are close to the physical limit, carbon-based chips have more room for theoretical performance improvement and lower energy consumption. According to reports, mainland researchers have mastered the preparation technology of carbon nanotube integrated circuits, and the circuit frequency is much higher than that of similar products in the United States.
As a magical two-dimensional material, graphene's excellent performance in electron transport also provides new possibilities for the chip industry.
So the United States, which originally wanted to use a chip to get stuck in the neck, now found that it was stuck, and the trick was used for a long time, but it turned out that it was no one else who was stuck, but himself.
In general, with the overcoming of technical difficulties and the rapid response of market verification, the technical path of "corner overtaking" of China's chip industry is becoming a reality.
