The resolution of any lithography system is a simple equation k1 * (LS /numerical aperture)
LS = light source of the system
NA = optics or mirrors and the refraction index of the medium.
k1 = factor for aberration, diffraction and such.
Decreasing the wavelength increase the resolution, increasing the NA increase the resolution and decreasing the k1 factor increase the resolution.
The most straight forward method is to decrease the wavelength of the light source, that is what ASML did by going EUV.
Is possible to use shorter wavelength laser in DUV but lasers with wavelength shorter than 193nm have technical problems.
The NA is hard limited by the refraction index of the medium for air is 1 and water is 1.33 and the optics, for a dry system the theoretical limit NA for a dry system is 0.8-0.9. One option is to use a high n-index fluid to increase the numerical aperture like n=1.6-1.7, but that fluid has to be highly transparent to DUV light.
The only factor left is k and there is were most of the resolution increase in the last decade has come. So i think they don't see more use to tweak the software and the hardware to archive minimal gains in resolution. They are starting fresh again with a with new type of lithography EUV and then tweak that to archive better resolution without too many tricks.

@tokenanalyst thanks bro highly appreciated, so EUVL is vital!

Important relevant quotes
substantially reducing the cost as the newly mass produced offering carries a price tag that’s nearly 50 percent lower than its peer products in overseas markets.

If running at full capacity, the base will be able to meet about 10 percent of the national need

Being 50% cheaper and another 9 such domestic facilities, foreign companies in this sector will be annihilated. Then start exporting...

SMEE has a different way of describing the capabilities of its DUVL. Different to that of ASML.
ASML describes its DUVL as having a resolution.of 38nm.
SMEE describes its DUVL according to Node or Process Node. In other words the DUVL can produce 28nm ICs using a single exposure. It can do 14nm with double exposure. Etc.
There is not much Western Literature on the SMEE DUVL as it will be mainly be sold within China.
Chinese Govt also wants to keep this low profile just in case it excites people like Ron Vara amd Marco Rubio.
There is no point for SMEE to promote the product in English to Western countries.
Maybe one day.
And by the way this Machine actually exists.
A lack of Western Media reports about it and its specifications, does not mean it doesnt exist.
Any further debate about this matter is bacically a waste of time and Data.

Why would SMEE promote the product to Western countries? It would take years just to satisfy the Chinese domestic market. However, in the larger picture I hope SMEE could proliferate semiconductor manufacturing globally as Xiaomi did for phones. There is a massive market in countries ASML is restricted to export to, as Russia, Iran, etc.

Admirable article but in the end..

There is a reason why the US is known world-wide for its harvesting skills.
I fear that it is too late for S.Korea to resist now. They should have made a smarter choice years ago

Anyway, whatever happens is a win for China. It has exposed the US dirty tactics to the public. Also exposed that western "fair" trade is basically the US watering you and then eventually harvesting you

Another chance to draw S.Korea closer to China's orbit.

All's fair in love and war and to honest I love this America first policy. America's first and foremost interests are to look after America's interests having an indigenous US company like Intel have the most cutting edge fabrication nodes in America is in America's interests.

America will stop at nothing - including fucking over Korea and Taiwan- to achieve her objectives.

The two countries should blame themselves for being naive enough to think that the US genuinely cares about their interests. They should have learnt from Japan and Huawei

Yeah, I agree completely.

I just don't understand the Americans.

It is like they want to turn South Korea, into another North Korea.

Not even the Chinese want to do that, gut their industries and leave them with scraps.

Maybe Japan is behind all of this?

:p
