Consider this a moderator reset.

I won't delete all the last few pages of posts because it was not unconstructive. But they were wildly off topic.

Any further posts from here that are off topic will be deleted. Exercise due restraint.

Been holding this 2 Chinese Publication for a while now and I want an experts opinion on this?

Huawei gets a new patent, it's about graphene transistors, the dawn of carbon-based chips is coming​

We all know that after the US chip siege from 2019 to 2020, Huawei's chip supply chain system can be said to have long since fallen apart.
This has led to Huawei not only being unable to manufacture HiSilicon Kirin chips, but also unable to directly purchase chips from chip companies such as Qualcomm and MediaTek.

As we all know, the importance of chips to a technology company is self-evident, so in recent years Huawei has been looking for a solution to the shortage of chips. Although it is alone, it is not without hope.

The graphene transistor patent obtained by Huawei recently can effectively increase the output resistance of chip components and devices, thereby maximizing RF performance. It is a new start for domestic chips.
In fact, Huawei started the research and development of graphene materials very early. It was reported that Huawei would launch graphene batteries before, but before that, graphene chips were ushered in first.

After Huawei suffered a blow, the sales of smartphones also fell from the world's number one to the fifth in the world, and its share of the global market fell from more than 20% to 8%. The chip blockade has become the most inevitable primary problem for Huawei to solve.
At present, the most advanced lithography machine in China is the 28-nanometer DUV lithography machine of Shanghai WeChat Electronics Co., which is obviously not enough for Huawei. The high-end chips designed by Huawei have been using processes below 7 nanometers, so why not make them in my country What about the lithography machine?

Ren Zhengfei said in a speech at a domestic university last year that it is not a problem for the lithography machine to get stuck. The related technology is in some public documents. It is not that we can't make it, but we can't make it, and we can't use other people's patents.

Therefore, while developing traditional chips, Huawei must actively explore new directions and open up new outlets. At present, both Tsinghua and Huawei are focusing on graphene transistors.
Compared with silicon-based chips, carbon-based chips are superior in hardness, electrical conductivity, and thermal conductivity. Although their thickness is 1/200th that of hair, their strength is more than 200 times that of hair.
Carbon-based chips can be said to have the best thermal and electrical conductivity, the strongest strength, and the lightest weight. Its performance is more than 10 times higher than that of traditional chips, enabling faster data transmission and lower power consumption.


At present, the device units that make up modern electronic information technology integrated circuit chips are almost entirely composed of silicon-based transistors. Therefore, they must have inherent shortcomings. Among them, speed and heat dissipation are the biggest bottlenecks they face.
In theory, the faster the chip speed, the greater the heat generation, and the greater the energy consumption. To solve these problems, the only way to solve these problems is to continuously improve the processing technology of traditional chips to shorten the distance of electron transmission.
Nowadays, TSMC and Samsung have almost reached the limit of Moore's Law in chip manufacturing, and it is very difficult for chip technology to break through after three nanometers. Obviously, traditional chips have developed to the final stage.
In other words, the physical limit of silicon-based chips is imminent. If you continue to catch up on the traditional track, it is of little significance, not to mention that for our country, this track is still facing blockade.


Nowadays, my country is constantly exploring new chip materials, and graphene is obviously the most qualified. Graphene is different from traditional chips. The transmission distance of traditional chips is constantly shortening, while graphene continues to increase the transmission speed of electrons.
In addition, graphene, known as black gold, is the material with the highest thermal conductivity known so far. By improving the quality of carbon nanotubes, it perfectly compensates for the excessive heat generation of carbon-based chips in terms of heat dissipation.
According to the data, once the traditional silicon-based transistors are changed to carbon nanotubes, the electron mobility can be increased by 1,000 times, the gate delay will be greatly reduced, and high-frequency operation at lower operating voltages can be achieved.


Secondly, because the free path of electrons in carbon nanotubes is particularly long, the movement of electrons is more free, and friction and heat are not easily generated. Therefore, the power consumption of carbon transistors in actual operation is very low.
Thanks to this, carbon-based transistors run 5-10 times faster than silicon-based transistors, but the power consumption is 1/10 of that of silicon-based transistors. Therefore, replacing the current silicon materials with carbon materials for manufacturing chips is a chip field. The most prone to corner overtaking.
In October last year, the Chinese Academy of Sciences achieved a major breakthrough in the field of carbon-based chips. It successfully developed the world's first 8-inch graphene single crystal wafer, and has formed stable small-batch production.

This fully shows that the current domestic graphene wafer production technology is at the international leading level in terms of the size and quality of graphene single crystal wafers.

The development of carbon-based chip semiconductor materials is only a key link in chip design. After technological breakthroughs, it is still necessary to find ways to increase production. Whether mass production can be achieved is an important prerequisite for commercialization in the future.
The production efficiency is low, the price cannot be lowered, and the market cannot be truly entered. To mass-produce, a large amount of production equipment is first required to form a related industrial chain. This time is at least three years.

Today, the world's largest semiconductor factory is still a silicon-based chip factory, including Intel, TSMC, and Samsung, all of which are fully developing 5nm and 3nm technologies.
In other words, in the next 5 years at least, the production of graphene chips will not be produced in these factories, and it is very likely to become the leader of emerging factories in this field, and the most suitable environment will be China.

According to expert analysis, after graphene transistors are put on the market, they will surely drive the development of my country's semiconductor industry. At present, the annual output value of my country's graphene wafers is about 300 tons.

Compared with traditional chip raw materials, the price of graphene chips is lower, which means that once graphene chips are mass-produced, today's high chip costs can also be controlled to a certain extent.
In May 2020, the academic journal "Science" published important results. The Peking University team produced a carbon nanotube array with a purity of up to 99.99% through an innovative process. This is a disruptive breakthrough in the semiconductor field.
Academician Peng Lianmao of Peking University said that compared with foreign silicon-based chips, the domestic carbon-based chips used in my country to process large-scale data are fast, low power consumption, and can save at least 30%.


Because carbon nanotube chips have obvious advantages in power consumption and performance, they have very broad application prospects and can drive traditional markets across fields.
In other words, the scope of application of carbon nano transistors does not only include electronic products such as mobile phones, satellite navigation, weather monitoring, artificial intelligence, medical equipment, and even defense technology and space technology.
With perfect structure, ultra-thin conductive channels, extremely high carrier mobility and stability, carbon nanotubes are likely to replace traditional silicon wafers in the future.
After Huawei released the graphene transistor patent, it has revealed the future development direction of Huawei's chips. The release of this patent has enabled my country to successfully gain a foothold in the world's leading position and win time to catch up with new technologies.

Achieving technological transcendence is of further significance for breaking the US monopoly on the semiconductor industry and promoting the development of my country's semiconductor industry.

Huawei discloses its graphene transistor patent to the world, and China's semiconductor field makes a breakthrough​

2022-06-26 22:45 HKT

With the opening of the 5G era, China's Huawei has become the world's only communications giant that can provide end-to-end 5G commercial solutions, which has made Western countries led by the United States start to panic.
After the first attempt by the United States to contain Huawei's development through normal commercial competition methods failed, it put Huawei and its subsidiaries on the "blacklist" of exchanges.
Other companies are forbidden to provide Huawei with 5G chips, parts and chip technology; both software and hardware require their allies to refuse to cooperate with Huawei's 5G network construction.
Today's Huawei is already fighting alone, and people can't help but wonder if we are really hitting the rocks with pebbles.

Graphene Field Effect Transistor Patent​

The answer is: no! Huawei's fighting alone is not the end here, this is a new beginning! The graphene field effect transistor patent published to the world recently is the best proof.
In this patent, Huawei stated that it can provide a graphene field-effect transistor, which improves the switching ratio and radio frequency performance by increasing the output resistance of the device, which can greatly shorten the processing time of various smart products.
The transistor includes a substrate, a first gate electrode, a second gate electrode, a first gate dielectric layer, a second gate dielectric layer, a channel layer, and source and drain electrodes.

The first gate electrode, the first gate dielectric layer, the second gate electrode, and the second gate dielectric layer are respectively located on both sides of the channel layer composed of AB stacked double (multiple) layers of graphene material;
The first gate electrode is composed of a first sub-electrode and a first connecting sub-electrode connected at intervals;

The extension direction of the first sub-electrode crosses the spacing direction of the source electrode and the drain electrode, and the projection of the first connecting sub-electrode and the channel layer on the substrate does not overlap;

The first sub-electrode and the second gate electrode are used to provide the channel layer with a vertical electric field perpendicular to the channel layer.
In fact, as early as 19 years, the Shenyang National Research Center of Materials Science, Institute of Metal Research, Chinese Academy of Sciences, produced vertical structure transistors to improve the signal transmission and processing speed of electronic components.

8-inch graphene single crystal wafer​

Not only that, at the Shanghai International Graphene Innovation Conference, the Chinese Academy of Sciences has made persistent efforts to develop a newer 8-inch graphene single crystal wafer, which has higher hardness, thermal conductivity and electrical conductivity than traditional silicon-based chips.
The publication of Huawei's patents for the ethylene field effect transistors means that it is just around the corner to break the monopoly of the semiconductor industry.


When Huawei was suppressed and blocked its chips earlier, it consciously introduced China into the predicament of studying lithography machines.
Because the lithography machine is the core equipment of chip manufacturing, according to the general logical thinking: if you want to manufacture a chip, it must spend a lot of energy and financial resources to develop a domestic lithography machine.
However, the production of lithography machines is extremely complicated. At present, industries that can produce lithography machines are prohibited from selling lithography machine drawings to China. Facing such practical problems means that China cannot complete chip research and development work.

Just when they thought the conspiracy was about to arrive, the graphene wafer developed by the Chinese Academy of Sciences turned out to surprise Western countries, calling them "lied" by China's anti-routines.
Western countries are full of confidence that China will fall into the lithography machine dilemma, but once thought that we should find another way to open another new world of chips.

The graphene exhibited by the Chinese Academy of Sciences is called the king of new materials. Carbon-based chips made of this material will reach the world's high-end level. What is more worthy of recognition is that my country's annual output value of graphene is rich.

Once other countries suppress and block China's raw material exports, the country will no longer suffer from such problems as raw material blockade.
Therefore, carbon-based chips made of graphene must be the icing on the cake for China's science and technology cause. In addition, my country's graphene wafers have also achieved small batch production.
The research and development of graphene wafers has gone from single-layer to single-crystal, from single-crystal to atomically flat large-area wafers, and from samples of only a few microns to 8-inch wafers that can be mass-produced. It is not easy for the R&D team all the way. .
In order to make the most of the research and development results and realize the mass production of graphene wafers as soon as possible, the Chinese Academy of Sciences quickly signed an agreement with the graphene functional platform.


The graphene material is used as a sensor of various physical parameters and used in combination with a radio frequency identification antenna to ensure stable small batch production of graphene wafers.

Graphene battery​

At the same time, graphene batteries made in my country are gradually put into use. In response to the country's call for "green travel", electric vehicles and electric vehicles are now on the streets and alleys.
Regarding the choice of electric vehicles, I believe everyone is most concerned about its battery performance: how long can it run? Is charging fast? Is the service life long?

In order to attract the eyes of consumers, the major electric vehicle brands have also worked hard to continuously improve and upgrade the appearance design and battery performance.

The appearance design can be solved very well, but the battery performance improvement is a big problem, and the graphene battery provides a shortcut for the performance improvement of the electric vehicle pool.
Well-known brands such as Luyuan, Emma and Yadi have successively launched their own graphene batteries as product innovations to attract customers.

There are three types of electric vehicle batteries currently on the market: lithium batteries, lead-acid batteries and graphene batteries.
Among the three types of batteries, lead-acid batteries are low in cost, large in size, small in capacity, and short in life; lithium batteries are small in size, light in weight, and high in cost; graphene batteries have large reserves, fast charging speed, and long life.
Therefore, many brands in the electric vehicle industry have successively launched graphene battery electric vehicles to effectively solve the problem of long charging time but short range of electric vehicles in the past.


Graphene batteries have also begun to show their talents in smart devices such as mobile phones and tablets. The charging time of mobile phones using graphene batteries is only a few seconds.
Graphene battery pits have good cooling and heating performance, and can work normally in extreme conditions such as low temperature of minus 400 degrees Celsius to high temperature of 120 degrees Celsius, keeping the charging performance effect unchanged;
Graphene batteries coexist with rigidity and flexibility: Even if this graphene battery is bent and tempered 10,000 times by you, its capacity remains stable.
More importantly, it will not have frequent explosions and injuries to a certain brand of mobile phone, because even if the battery is exposed to flames, it will not catch fire or explode.

From this it appears that graphene is well-deserved as the "black gold" and "king of new materials". my country has already used graphene as a new energy source and invested a lot of manpower and financial resources in research and development.

At present, the number of applications for its patents has far surpassed the United States, Japan and other countries, ranking first in the world, and it will surely set off an innovative technological revolution in the future.

Chinese AI technology​

Of course, China's innovative technology is not limited to graphene batteries. Today, China's AI technology is even more comparable to that of the United States. Compared with the 5G era, the future will belong to China.

Technologies represented by artificial intelligence are widely used in industries such as industrial production, e-commerce, news media, and financial scenarios.
my country's artificial intelligence technology has also been relatively mature. In the military, by controlling UAVs to conduct warfare, guarantee national border security and deter foreign enemies;
In industrial manufacturing, the traditional industrial model is changed through data analysis and data modeling to improve production efficiency;


In education, integrate and share high-quality teaching resources to reduce the gap in education resources; in agriculture, precision farming and harvest fruits.
In all of the above industries, China's artificial intelligence technology has vividly demonstrated its charm and capabilities, which are inseparable from the hard work of the vast number of scientific researchers.
In order to effectively integrate scientific resources, our country is also actively encouraging school-enterprise cooperation, so that school laboratories can receive corporate financial assistance, and companies can quickly solve problems by connecting with well-known school experts.
China has always maintained a low-key attitude in doing things, knows how to accumulate things, and it is expected to lead the world in the three technologies of artificial intelligence, genetic science, and materials science that are changing the world.

In the previous three industrial revolutions, China has always been in a difficult state of survival under the control of others, and now the sleeping lion has awakened.

I believe that when the fourth industrial revolution is approaching, China will seize this opportunity tightly and take advantage of the victory. I believe that China's science and technology is bound to become the world's top technology.

So this all seems fantastic and really good news for anyone hoping for China closing the gap being denied equipment from ASLM and other companies by the US - ironically the embracer of market competition. For myself, with very limited knowledge in this field but still interested in Chinese success, I would like to hear what people on this thread think it will take until China reach the TSMC and leading edge technology in an industrial level. I use to say to my friends that in 5 year China has closed the gap. What is realistic according to You?

@Fredrik hi bro welcome to SDF, I hope you enjoy your stay here and participate in lively discussion with our esteem members par excellence. Regarding your question from what we're seeing you're correct, most of us expect the year 2025, the timetable for Made in China 2025. Now TSMC will be a generation ahead, NO question about it, for us it's a race to be second place as there is no shame behind our compatriot...lol, IF TSMC mass produce its 2nm chips in 2025/26 and China delivered its own EUVL, SMIC may introduce its own 3nm chips, A wild claim BUT as Liang Mong Song had mentioned that the 5nm and 3nm are being research, they may use the SSRF as a tool to experiment with materials while waiting for the IHEPS SSMB to finished its construction.

SMIC's Liang Mong Song says that SMIC's 7nm node has already completed full development, and is preparing mass production April 2021. More surprisingly, the designs and most of the development for 5nm and 3nm nodes have already been mostly completed.​

The following is the full text of Liang Mengsong's resignation:
Letter to the Board of Directors
Hello, chairman and directors!
I know that we will make a very important personnel appointment decision at this meeting today.
Currently,

is facing various pressures from the United States, leading to serious threats to the development of advanced technology. I believe that today's personnel proposal will inevitably affect the company's prospects.
It has been more than three years since I was appointed as the co-CEO by the board of directors in November 2017. In these more than 1,000 days, I almost never took a vacation. Even in June 2019, when I was experiencing life At the most dangerous moment, I never gave up, and I never let you down.
During this period, I tried my best to complete five generations of technology development from 28nm to 7nm. This is a task that an average company takes more than ten years to accomplish. And these results are obtained by more than 2,000 engineers led by me, working hard day and night. Of course, the trust and support of the chairman and the directors in the past is also a key element of success.
I originally came to mainland China not to seek high-ranking officials, but simply to contribute to the mainland's high-end integrated circuits. At present, 28nm, 14nm, 12nm, and n+1 technologies have all entered mass production, and the development of 7nm technology has also been completed. Risk mass production will be available in April next year. The 8 most critical and most difficult technologies of 5nm and 3nm have also been carried out in an orderly manner. Only when the EUV lithography machine arrives, we can enter the full development stage.
It seems that my short-term goal seems to have exceeded expectations and was successfully achieved.
I received a call from the chairman of the board on December 9th, last Wednesday morning: Mr. Jiang is about to become the vice chairman of the company. I was very surprised and puzzled about this, because I didn't know anything about it beforehand. I deeply feel that I am no longer respected and distrusted. I think you should no longer need me here to continue to work hard for the company's prospects. I can rest for a while.
After the company’s board of directors and shareholders’ meeting have approved Mr. Jiang’s nomination, I will formally submit my resignation. But the company should give a comprehensive and fair evaluation of my contribution over the past three years, and I should have the right to accept and appeal.
I solemnly tell you that I do not have the slightest intention to influence your next vote on this personnel appointment, but I think I should let everyone know my true feelings.
My statement hopes that Ms. Guo Guangli, secretary of the board of directors, can be included in the official meeting minutes of this interim board of directors.
Thank you all.
