The latest news is that China's 7nm chips are manufactured using synchrotron radiation, which has 40 times the capacity of EUV lithography.

This large research facility was originally designed for scientific research in the extreme ultraviolet band.

That is a big innovation.

 

[MH.Yang]

Due to the global division of labour, if photolithography is too large to be transported from Europe to Asia, so the semiconductor industry is now using ASML's compact lithography technology.

The SSMB-EUV light source used in China has an output power of >100000KW, a capacity 40 times that of ASML, an accelerator length of >200 metres and a width of >20 metres alone, and it is capable of using dozens of EUVs at the same time with a beam splitter. The whole SSMB-EUV light source volume is equivalent to a photolithography factory. The construction of SSMB-EUV light source requires a complete industrial chain and huge capital investment, and China is the only country that can meet all the conditions.

so now u just gonna straight up make up lies

 

[TriptiD]

Source of this news ? What is the unit cost of chips manufactured using this technique?

So, it uses a different method.

No wonder Huawei dares enough to release his own chip.

I thought it used DUV tricks.

This ^ if there is a source, I'd like to see it for educational purposes

Cost...it's weird when talk about cost when it comes to China manufacturing thing

The question has been asked since 1990s and we deep down have always known the answer

Sooner or later China will get it done like it has always been the case

So, it uses a different method.

I doubt it's been employed yet

We are not talking about t-shirts and towels here.

The reason that I am asking about costs is that the chips could have been made using new tech in an experimental setting- which could be prohibitively expensive in a commerical setting. For example, you can "manufacture " gold in a particle accelerator, but the cost is prohibitive.

That question is easy to answer. If they sell only 100,000 7nm chips, your suspicion may be correct. But if they sell 100 million 7nm chips, they could not be making it at a loss and survive. In 2022, 1,400 million smartphones were sold. So, 100 million is only 7% of smartphones market.
