Before the recent research , I didn't know they already have a working EUV prototype in 2017.
They should have working industrial grade EUV in 2025,
From 7nm to 5nm EUV power increased.
From 5nm to 3nm even more EUV increased. Depends how much their EUV light generation module enhanced.

Its not just multipattening like DUV.
I think the higher laser poewr is if it's they want to do high NA.

Still, there are several pieces that must come together before high-NA EUV is ready, including the scanner/source unit, masks and resists.

There are major challenges in all fronts. According to HJL Lithography, the main challenges are: 1) resists; 2) source power; 3) small depths-of-focus at 0.55 NA; 4) lens polarization control; 5) stitching issues; 6) mask making; and 7) cost.

About 2006. Your original question about power number from Harbin institute of tech DPP is it IF power. Yes it is. I thought it was source power originally. I was wrong. Only IF power, which is the final filtered/collected power make sense for the application because source power still unfiltered.
ASML is equivalent to SMEE, the final assembly house for EUV equipment., It gets components from everywhere.

Huawei doesn't have to good at the field but its money would be very helpful. Chinese academy of science, Harbin institute of technology, Chanchun institute of optics are quite strong on research. They just need money.

Money will go a long way. For EUV projection started 15 yrs ago, CAS, Harbin institute of tech , and Chanchun of optics probably has budget of in thr range $200K. Usually, there's not a whole of money from government for research institutions. One of invoice for the set of mirrors used in this project is about $20K.

Now if industry players joined in and set up an consortium for EUV alliance and funding for like$50million. That would make a huge difference. Players like huawei, SMIC, ZTE, Byd, Gree, Baidu, Alibaba.. $50million -$100million easily doable for those big guys.,

Research is best when doing through trial and error. It will take alot of money and time but this process will exhaust all possible ways. Through this style will all ins/outs will be studied.

If 15 years ago, big funding and trial and error, an optimal industrial grade solution would be arrived by now.

As of now, China has a research EUV prototype but industrial grade solution effort just started.

Better late than never ... huge thanks to Trump to wake the Chinese up ;)

Yes, You are correct but
The reason people prefer high NA and single pattern with higher power at smaller node versus same NA , same power and multiple pattern is the increase of mask steps which translate to higher cost.

So in 2025, they need to able do single pattern at 5nm or 3nm with multiple patterns if additional cost justified

We'll just have to wait and see then.

The technology is there, not a fairy tale. So it's just a matter of catching up.

If they deny technology to China, then that technology is fair game for espionage.

Or use a Beyond EUV (6.7nm wavelength) which IIRC, uses a rare earth element in the place of tin.

I think there's some preliminary research in China and Japan on BEUV light sources, but BEUVL would probably require its own specialized optics.

It would be pretty cool that korean and taiwanese have to develope their tech based on chinese equipments will do damage to their sense of superiority over mainland. That's an area they don't have.

But the main thing is who can out-isolate whom competition between China and US. Forcing US allies to switch to domestic equipments to serve China market is a very important strategy to counter GOP's "Beat China" plan

Tom cotton's "Beat China" plan, continuing trump economic warfare against China.

This part is very telling
The senator singles out Japan as a place that could buy more American goods, and points to Malaysia and Vietnam as having labor forces that could produce these goods at competitive prices.

So despite having his declared his intention of sending CCP into the "ash heap of history", Cotton suggests turning to communist Vietnam instead of 'democratic' India. Indians love daydreaming about the West building them up as a counterbalance to China, but the idea that the West is going to build a potential competitor of India's size is just nonsense.

Okay.....with EUV Light Source what we should all be looking at is Source Power. Source Power is the measurement of the amount of EUV Photons delivered to the Scanner to enable wafer exposure.
It is through looking at Source Power that we can calculate the productivity in Wafers Per hour.
It is said that 250W Source Power is required for mass production of 125 WPH.

The NXE3400 has a light source with Source Power of 200 - 250W at intermediate Focus.
The CAS EUVL has a DPP light Source with Source Power of 150W+ currently.
Old School mentioned that the DPP Light Source has a Power range of 114W to 180W.
If this is accurate, then CAS is well on its way to achieving a source Power at Intermediate Focus of 200W+ by 2025.
By 2025 CAS should hopefully increase the Power of the DPP or LPP Light Source to at least 200W+.
This will enable some type of mass production to take place.

Below is part of an article explaining about this Source Power and how it relates to productivity in Wafers Per Hour.


At the recently held Semicon West tradeshow in the United States, lithography vendor ASML announced it had achieved an important and long-elusive milestone: the demonstration of a 250-watt EUV source. Source power—a measurement of the amount of EUV photons delivered to the scanner to enable wafer exposure—equates directly to productivity. Chipmakers have long insisted that source power of 250W would be required to achieve throughput of 125 wafers per hour (WPH) and the inability of ASML and Cymer (which ASML acquired in 2013) to push the technology to hit that mark has been considered the primary roadblock for EUV development in recent years.
Michael Lercel, director of strategic marketing at ASML, said the company has demonstrated 250 watts “rather consistently by really understanding the conversion efficiency in the source and putting the right controls in place.” He said the source that has demonstrated 250W has not yet shipped.

Leading edge chipmakers including Intel, Samsung, TSMC and Globalfoundries are planning to insert EUV into high-volume production sometime in the next two years. ASML demonstrated back in February throughput of 104 WPH and executives said even before the 250W source power was demonstrated that the company had a roadmap to get to 125 WPH.
The 250W source power milestone represents an improvement of 10 fold over the past five years from about 25W in 2012. Delivering a presentation on the economics of EUV for production, Lercel joked that when he worked at Cymer in the early part this decade the goal for reaching 250W of source power “was always next year.”

I don’t think this is quite right. The ultimate value that matters for WFH is the amount of light that’s actually exposed at the wafer, which has its own spec value. That’s source power minus all the photon loss along the optical path. I think source power is obviously a very important value, and assuming that there shouldn’t be *too* much range in how much photon loss different optical designs impose it should be a good proxy, but if that assumption doesn’t hold the requisite source power for comparable performance with ASML’s NEX3X00 series could be higher or lower.

The intention for posting this was to clarify some matters regarding the Harbin Institute DPP Light Source and its Source Power in relation to Wafer Production per Hour. There had been some confusion earlier on about the Specifications of the Harbin Inst DPP Light Source.

Anyway the full article here.
