@foofy they really don't trust the Japanese, there is a equivalent machine from NIKON and they don't bother to acquire one. Maybe the EU had the guts to say no to the US especially on the matter of DUVL?
i don't think Japan has equivalent machine.

Chinese researchers have made a breakthrough in carbon-based semiconductor materials with higher efficiency and lower costs compared to silicon-based materials, marking a step forward in the domestic chip industry.

Issues that have long troubled the preparation of carbon-based semiconductor materials have now been solved, including material purity, density and area,

according to the latest scientific research achievement by the Beijing Institute of Carbon-based Integrated Circuits, an organization engaged in the research and development (R&D) of semiconductors.

"Carbon-based semiconductors have the advantages of lower costs, lower power consumption and higher efficiency," said Peng Lianmao, a professor with Peking University who is leading the carbon-based semiconductor project.

At present, most chips use silicon-based integrated circuit technology, and high-end chip technology has long been monopolized by foreign manufacturers.

China's imports of semiconductors have risen significantly during recent years thanks to rising domestic demand, with import value exceeding $300 billion for the first time in 2018. Nearly 85 percent of market demand depends on imports.

"Our carbon-based semiconductor research is at the world-leading level," said Peng.

The cutting-edge technology can be applied to multiple fields including national defense, satellite navigation, weather monitoring, artificial intelligence and medical equipment. And if carbon-based technology is applied to smartphones, it will greatly extend standby time due to lower power consumption.

Carbon-based semiconductor research and industrialization are indispensable parts of China's third-generation semiconductor technology, poised to equip the country with the advantages to race ahead, industry analysts said.

Xu Haitao, head of the R&D department of the Beijing Institute of Carbon-based Integrated Circuits, told the Global Times on Wednesday that due to the gap between laboratory and factory, it will be some time before technology is upgraded for the industrial application of carbon-based semiconductors. More partners are welcomed to participate in the process to accelerate the pace.

Bypass the lithography machine? China“s graphene technology breakthrough, beauty scientists lament: too soon


Insurmountable barriers​

In the competition with Western technology blockade, the high-end lithography machine equipment has once become an insurmountable barrier for domestic technology companies. The Dutch ASML is the only manufacturer in the world that can manufacture EUV lithography machines, but Its equipment contains nearly 30% of American technology and parts. Although it has shown good in the domestic market several times, it has never been able to obtain a shipping license.
In the era of intelligence, the chip can be called the "brain", especially for technology companies such as Huawei that have made great contributions to my country's 5G business, its importance needless to say. To solve the chip problem, it is necessary to leapfrog the lithography technology. To this end, the Chinese Academy of Sciences took the lead, and President Bai Chunli said: included lithography and other card-neck technologies in the urgent scientific research task list of the academy.
Bypass the lithography machine? China“s graphene technology breakthrough, beauty scientists lament: too soon


Facing the importance of Chinese Academy of Sciences and domestic chip companies to the field of lithography, foreign media are not optimistic. At the time of the CIIE, ASML said that even if you give you the manufacturing drawings of the lithography machine, you may not be able to make it.
Even the founder of TSMC Zhang Zhongmou waited to pour cold water more than once. The research and development of lithography machines is no less difficult than the atomic bomb. The limitations of tens of thousands of parts and assembly technology are very difficult for the whole country. Technology can only be down-to-earth, and there is no corner overtaking.

Perhaps, the development of domestic chips is stuck in the link of lithography machine, which is the result that Western technology blockade most wants to see.

Chinese Academy of Sciences presents scientific research results​

However, the Chinese Academy of Sciences recently announced an important scientific research result, which amazed those who are self-righteous. Z14z "Isn't it a good lithography machine, why did you bypass it?", American scientist Reluctantly said that this is too fast. After 5G technology, China will lead the world in another field.
At the international graphene innovation conference held a few days ago, Chinese Academy of Sciences showed the developed 8-inch graphene wafer for the first time. This result reached the top level in terms of quality and size.

Perhaps many people are relatively new to graphene wafers, and they may even ask, what does this have to do with lithography machines?
Bypass the lithography machine? China“s graphene technology breakthrough, beauty scientists lament: too soon


First of all, we must be clear that the important raw material for carbon-based chips on graphene wafers. The 21st century is the carbon era. In this field, almost the world is seeking breakthroughs in raw materials, because this is the only way to make carbon-based chips. , And my country’s Chinese Academy of Sciences is the only scientific research team that has accomplished such an achievement. The chips manufactured by the
lithography machine are silicon-based chips. With the same process, the performance of carbon-based chips is at least 10 times higher than that of silicon-based chips. More importantly, silicon materials are the products of the last century. Improved, silicon-based chips are accurate to 5nm and 3nm, which has approached the physical limit. In other words, the development of chips has come to the stage of re-selecting semiconductor materials. The 8-inch graphene wafers brought by the Chinese Academy of Sciences are undoubtedly the best quality. Carbon-based chip raw material . There is a more important reason why

surprised the foreign media. Based on the performance of graphene, bypasses the complicated high-end lithography technology in manufacturing. It can also be understood as the requirement for lithography technology. Not as demanding as 5nm silicon-based chips. Z15z

is written at the end

Although the lithography machine is very important, it is an indisputable fact that the silicon-based chip has reached the ceiling. If we continue to study high-end lithography technology with a nationwide effort, even if we succeed, by then, the silicon-based chip may It is no longer indispensable.
's research and development of carbon-based chips is equivalent to the fact that we have already begun to run in the new era. From passive beating to formulating rules, the Chinese Academy of Sciences has officially launched the sword, because once it falls behind, the price to be paid is too great. What do you think of this

Thank you.

Thats why u asked the question about Grapene based chips. It is obvious that silicon based chips are at their last eggs and new technologies are needed now. So while developing EUV machines is ok, it is good that the Chinese gov can plan for the future where (most probably) silicon based chips wont exist

not controlled under EU export control laws. There is no legal basis to deny the shipment

That's like spending less effort to improve and compete in making rocket engines as the nuclear power age is coming around back in the 1960s when the Americans and Soviets were trying to develop (and testing) nuclear powered aircraft and rockets.

There is no real indication that silicon is anywhere near being made obsolete. Any new alternative material/principle is going to take time to make commercially available anyway.

yes. this machine can do 5nm with multi-patterning

Even if the machine is accurate enough to do this it will require a lot more manufacturing steps which will be slower and require more etching and more materials than using EUV.

A lot of technologies tried to replace bulk silicon in the past like SiGe. They typically end up used in niche applications only.
