How do are the various parameters of EUV machines related? For instance, how does the wattage of the source relate to resolution and throughput? All of these machines generate UV light from the same source (tin droplets), so how come some have better resolution than others? How fine a resolution can the Changchun machine reach initially and then as the user pushes it?
Resolution is based amount of EUV light collected by the projection mirror directed to the wafer

High NA means the projection mirror sized gonna be big which help to collect more light.

You gonna see gigantic projection mirror.

You also need to enough EUV light otherwise if its too dim, larger sized mirror doesnt have enough light to collect. So, the resolution is combination of light and the physical ability of mirror to collect light

Higher wattage will help increase throughput.

All those machines are not the same. Higher wattage of EUV requires more powerful laser to zap the tin that generate more EUV light.

China still stingy in terms of tech investment. Recently, it gives SMIC $2.2 billion for investment. Come on, this is the most critical point. It should be at least $10billion

Yet it loans about $150 billion to African nations for infrastructure building. Now african asking for debt forgiveness due to virus.

Still cling to old mindset. Infrastucture and mineral resourced are tangible while R&D is not to them.

I guess infrastructure , train , ship building labor intensive are China bread and butter.

They got some incompetent advisors there.

Go figure.

I agree it should be more. The new state funded injection will increase SMIC's registered capital to $6.5 billion according to several sources.

Well 150 billion is over 10 years and half of it go back to purchasing Chinese good and service meaning employment for Chinese people
Most of the investment is to facilitate transportation of Chinese owned mining right and industrail estate.
And the rest go toward raising the living standard of African so that they can buy Chinese good in the future Not a bad investment.

This is all for African support in restoring Chinese right in United Nation and forcing the west to accept China from 70's on which lead to Chinese economy growing from 200 Billion to almost 14 trillion now

But I do agree China spend awful a lot of money for bragging right as "friend of Africa" when most of the African elite despise China since most of them are western educated. And expect handout and sense of entitlement when all those money are earned from toil and sweat of Chinese people from back breaking work

You are right there is better way to spend the money

The more worrisome thing is they dont have the right people as advisors. They just randomly give some funds. They dont know what it takes.
China also gives WHO $2billion. Invested $2 billion to SMIC. Not sure if they know what they doing. Take a look at TSMC, invests $12billion in US and its only a company not a big country.

Thats why i advising huawei to get into semiconductor manufacfuring because if it does it can provide leadership in the future. I dont think Chinese government have the right people to provide that kind of leadership for the industry.

China's Africa investments are highly debatable because African countries like Nigeria are some of the most pro-China countries in the world. Africa and its resources are also the main reasons why China has such a strong mining presence and monopoly of central African mines.

I think $2.2B is what SMIC can intelligently use right now and is what they requested. You can't just pour in money for progress infinitely; if you gave SMIC/SMEE $1 trillion, it doesn't mean they'll have everything ready in a month. I'm sure if they requested more money because they can use it for progress towards Chinese high-performance semiconductor independence, they'd have their funds, and it wouldn't necessarily be announced.
