On October 7, the US government introduced the strictest chip management measures for China. Globally, exports to China are prohibited as long as high-end chips are made using American equipment. Not only chip exports, but also chip production and manufacturing equipment.
Let me talk about the chip first. I roughly divided the chip into several categories:
1. Processing chips: CPUs for mobile phones and computers. High-end CPU brands mainly include Intel (PC side), AMD (PC side), Qualcomm (mobile side)
2. Memory chip: mainly in mobile phone storage chips,
3. Display chips: mainly GPU graphics cards, mainly Nvidia
4. Smart chip: Artificial Intelligence , smart voice, smart watch , smart TV, etc.

Two major factors restricting chips: design and manufacturing
In terms of design
my country's Huawei is actually ahead, and can even wrestle with Qualcomm .
Take Kirin 9000 5G for example. It uses the world's most advanced 5nm process technology , and its architecture design is even more precise, including more than 15 billion transistors. In terms of transistor count, integration degree, and performance, it surpasses most mobile phone chips on the market. Its CPU adopts an 8-core three-speed energy efficiency architecture, with a maximum main frequency of 3.13GHz.
Many friends may not know what the 8-core three-speed energy efficiency architecture is. The so-called "8-core" consists of a super-large core, 3 large cores, and 4 small cores. During the operation of the mobile phone, it does not use all the chip cores, but consists of 8 cores to form three gears, performing more complex and detailed operations. As for the performance in GPU and NPU, it is even better.
But what makes people helpless is that the United States has put the whole world in suppressing Huawei and does not allow chip manufacturers to produce an Kirin chip for Huawei. The Kirin chip was declared premature as soon as it was born.
Of course, not only Huawei, but other companies in my country can design high-end chips, but also suffer from lack of manufacturing capabilities.

In terms of manufacturing
chip manufacturing is a very complex process. The manufacturing of different chips requires different equipment. In general, these devices are inseparable.
includes lithography machine , plasma etching machine , ion implanter, reactive ion etching system, single crystal furnace , wafer scriber, wafer thinner and gas phase epitaxial furnace equipment, etc.
is especially the most difficult to overcome with lithography machines. The lithography machine is monopolized by ASML of Dutch . The unit price of a 14nm lithography machine exceeds 100 million US dollars.
The key is that we have money, and they don’t sell it yet, so the domestic chip manufacturing capacity has always remained at 14nm, two generations behind others (7nm, 3nm).

Why is it said to hurt one thousand enemies and lose eight hundred themselves?
At this stage, my country has the capacity of mass production of 14nm chips. Moreover, SMIC uses existing technical resources and special processes to produce chips with a chip capability of no less than 7nm. The first generation of N+1 chips have been mass-produced, and N+2 is also stepping up research and development. Once successful, its area will be infinitely close to , Samsung and TSMC's 7nm process. This means that more than 90% of my country's chip demand can be self-sufficient and no longer have to look at other people's faces.
And don’t forget that we also have Huawei’s “dual core superposition” technology, a process technology that superimposes two 14nm chips to produce nearly 7nm performance.
It can also be seen from this year's data that my country's chip imports have decreased by 54.5 billion in 8 months. This also indirectly shows that foreign chips can no longer be sold. Isn’t it also a loss for them? When our technological breakthroughs come, the chip price will be just around the corner.
