@tokenanalyst Bro it only mean one thing, the confirmation that SSA800A had pass its verification and is certified.

How did you come up with that conclusion ?
@antiterror13 Sorry sir and I apologized I may have my mental gymnast moment, I forget to put a question mark at the end...lol joking aside usually The Chinese will release an official statement after the product is in mass usage and with this post of @tokenanalyst for ME is one of many hints that the SMEE DUVL is doing well and may well be certified.
I can't say for sure, all can say there was an onslaught of patents in immersion lithography in 2021 by SMEE, CHEERTECH, the hated U-Precision, RSlaser and UPoptoelectronics all involved in the 28nm immersion lithography project.
@tokenanalyst and all at once, coincidentally? Bro I may be gullible BUT I based my gullibility on facts not vaporware.
@Vichysoy bro not only in graphene BUT carbon based material as well.
Graphene technology has made breakthroughs, and overtaking in the chip field can be expected

A recent news is exciting!
The Chinese Academy of Sciences has made a major breakthrough in the field of carbon-based chips, and the performance of conventional silicon-based chips is increased by 10 times!
We know that in the field of semiconductor silicon-based chips, we have always had a big gap with foreign advanced technology, and the possibility of catching up in the short term is also very small. The important point is that we lack high-precision lithography machines. Therefore, we must To achieve corner overtaking, we can only find a way to bypass the limitations of the lithography machine and upgrade the basic material direction of the chip. At the same time, the traditional silicon-based chip manufacturing is close to the bottleneck and is about to reach the limit of Moore's Law. The highest precision in the future is only 2 nanometers. , So silicon-based chips will not be the only material for future chips.
As a result, China's R&D direction shifted to the carbon-based field.
Carbon-based chips are also called graphene chips, because the main component is graphene carbon nanotubes, why choose graphene?
Because compared with other carbon-based materials, graphene is 200 times stronger than steel, but its resistivity is only 10-6Ω·CM, which is 1000 times less than copper, and its electron mobility is more than 15000 cm2/V·s, which is higher than silicon 100 times, and its thermal conductivity is as high as 5300W/M·K, which is 10 times higher than silver.
The three characteristics of high strength, high electrical conductivity, and high thermal conductivity make graphene the first choice for carbon-based chip materials!
And carbon-based chips are dozens of times higher than silicon-based chips in terms of stability and other performance.
Since it is so good, why hasn't it been commercialized?
Because there is a problem that has not been solved: that is, the inability to achieve superconductivity.
The superconductivity of graphene is also a world-class problem that has always plagued R&D personnel.
In 2018, the 22-year-old genius Cao Yuan published two papers on graphene superconductivity in the international scientific research journal "Nature", and for the first time proposed the theory and method to break through the problem of graphene superconductivity. "The magazine praised it as the driving force of graphene.
It is precisely by virtue of Cao Yuan's breakthrough research and development theory that at the International Graphene Conference in October 2020, the Chinese Academy of Sciences showed for the first time the 8-inch graphene single crystal wafer developed by China, which is a necessary condition for the manufacture of graphene chips. !
It also marks that China has taken a leading position in the world in terms of the size and performance of graphene single crystal wafers.
The prospects are very bright, but there are still many problems to be overcome in order to fully realize large-scale commercial use. The biggest problem at present is the extraction of graphene.
At present, graphene refining methods mainly include chemical refining and mechanical refining. Mechanical refining has the problems of uneven thickness and difficult to control size, while chemical refining is due to physical changes that lead to a low pass rate.
We have achieved technological breakthroughs in the most difficult field of graphene superconductivity, and we believe that it will not take long to solve these problems in graphene refining.
We believe that in the future, we will achieve corner overtaking in the field of graphene chips.

This war is a disaster for all Europe. We are stopping trade with Russia and revert to other sources (read US) for oil and gas. This war will move back the clock in Europe of 40 years! US is fully winning here, and they will not stop.
But many people here think China will be next. Your trilion $ credit in U.S. securities is your weak point. US can (and will) freeze it at any time in the future, for instance to "make China pay for COVID". For your information on European press (fully US controlled) started again this week to appear articles about virus's lab leak theory....
@european_guy yup total US investment in China is greater than $1 trillion and those are tangible asset, not Fiat Money. 1 in 1 exchange doesn't seem bad. And China is willing to sell the rope to form a noose to hang themselves.
