Maybe. Just Maybe.
But there's always the possibility that it may be not. Anyways.
This is a done deal. Although I am no engineer, this is just confirmation that EUV will be in China soon.
What is Extreme Ultraviolet light?
(copied from internet)
Extreme ultraviolet lithography (also known as EUV or EUVL) is an optical lithography technology using a range of extreme ultraviolet (EUV) wavelengths, roughly spanning a 2% FWHM bandwidth about 13.5 nm, to produce a pattern by exposing reflective photomask to UV light which gets reflected onto a substrate
What is Deep Ultraviolet light?
Definition. Deep Ultraviolet (DUV) Photolithography is the process of defining a pattern in a thin photosensitive polymer layer (photoresist) using controlled 254–193-nm light such that the resulting polymer pattern can be transferred into or onto the underlying substrate by etching, deposition, or implantation.
That is the difference.
The wavelength of the light, that light which is beamed out of that laser or whatever.
How do we change the wavelength of a light source?
We pass it through a prism, or lens!
So what they are really saying, some people in the US government, is that the Chinese do not know that light travels in waves (particles too), and the Chinese do not know that a lens can change the wavelength the light.
All the Chinese have to do to complete the EUV, is experiment a little with different lens construction, such as having several lens in a tube, such as a microscope or telescope.
In fact, if there is only one lens in a microscope, the object being viewed is still travelling through two lenses, one is the scope and one in our eyeball.
That is the bottleneck, how to build or machine that lens, or a set of lenses.
If they already have DUV, then EUV is replacing the lens. They landed on Mars. They can do this.
Once they replace the lens and fire it out of the laser, it could look like this.
