745 x 1100 mm exposure region with 0.5 um resolution is incredible and world class. Let me explain.

Linear resolution per exposure area is a measure of the alignment precision required of an instrument. Typically as dimensions get larger, tolerances also get larger since tolerances are usually described as % deviations. So how tight are the tolerances here?

745x1100 mm exposure area with 0.5 um resolution is linear resolution per exposure area of 1.22x10E-6 um/mm2.

For comparison, ASML TwinScan EUV has 13 nm (0.013 um) resolution exposed for 26x33 mm.

That is linear resolution per exposure area of 1.43x10E-5 um/mm2.

The tolerances required for precision UV exposure of such a huge area is tighter than that of even EUV.

I suppose that require an advance optical lens system to get a high intensity, wide area image and a high precision wafer stage.

In their new patent looks like they want to get the same area as the input while keeping or even increasing the resolution. Very different from frontend lithography lens systems that look to increase the resolution by decreasing the area.

Pretty much capital starved.
More like oversaturated. There is no way that so many startups will survive. The industry is bound for consolidation.
So many companies want to make MCU but can they really compete against gigadevice . Many image sensor , isp , display drivers but there is no way that they can complete with omnivision or hisilicon. AI chip is another fad. And in compound semiconductor will they be able to complete against sanan or byd semiconductor. They VCs will get burned.

So SMEE will deliver its SSA800 DUVL to Huawei in the middle of the year (May or June) and Huawei will then produce its 28nm and 22nm chips and maybe in 2023 its kirin 14nm 3D chiplet.

Since 2021, Huawei's mobile phone business has been hit hard due to chip supply, and the impact has continued to this day. In order to solve this problem, Huawei also tried to enter the research and development of lithography machine, but the research and development process was too long and Huawei could not wait, so Ren Zhengfei decided to build an independent chip supply chain.

Earlier, Huawei revealed that it is already building a 45nm chip factory. As time goes by, Huawei finally heard new news. It is reported that Huawei has completed the assembly of the 28nm chip production line and is fully autonomous and controllable. As long as Shanghai Microelectronics delivers the 28nm lithography machine on time in the second half of the year, Huawei will be able to achieve 28nm chip production.

Ren Zhengfei is right​

When we are all still looking at TSMC, Ren Zhengfei has already seen through. He believes that the United States is trying to monopolize the chip supply chain. TSMC, as a global chip manufacturing giant, will definitely be regarded as a target for killing chickens and monkeys, so TSMC can no longer find Kirin. For chips, Huawei must give up illusions.
Now it seems that Ren Zhengfei is right, but in order to survive, Huawei has also asked Qualcomm for assistance. Although it has obtained a supply license, they are all outdated chips. To this end, Huawei finally took action.


As we all know, Huawei has outstanding technology in the field of communications. Every year, it sells a large number of terminal equipment to the outside world. In addition, the unmanned driving system and electronic products that are involved now require chips. The data shows that 28nm chips can meet the current market. % Of demand, and if Huawei wants to completely get rid of sanctions from the United States, it must build a copper wall in weak links.

Now that Huawei has completed the 28nm chip manufacturing line, it just confirms the promise made by HiSilicon, that is, it will not make any kind of layoffs. Huawei will not only design high-end chips, but also produce high-end chips in the future. This is Ren Zhengfei's pattern.

Of course, if Huawei wants to revitalize its mobile phone business again, it needs to do the following three points.
First, based on the 28nm chip production line, first meet the chip supply of terminal equipment, and achieve independent survival first, and then try to develop independently.

Second, to make up for the shortcomings of Huawei's mobile phones in terms of chips with the advantages of the Harmony system's simplicity, smoothness and power saving. We all know that Apple is about to use 3nm chips, and Qualcomm is also planning. Only Huawei is still in chip accuracy. On the other hand, if Huawei's mobile phones want to compete with them on the same stage, they must have their own unique advantages.
The success of Huawei's mobile phone lies in its refusal to homogenize. First, the Kirin chip is supported by the Harmony system. This is Huawei's next opportunity.

Third, continue to sell mobile phones in limited quantities and continue the brand effect. It is difficult to predict how much Kirin chip inventory will remain, but what is certain is that Huawei has already begun to sell mobile phones in limited quantities. There are only two reasons for this: insufficient number of chips, and second, continued mobile phone business. No matter how the market changes, Huawei has not realized the independent supply of high-precision chips, "hungry marketing" is not a problem.

Concluding remarks​

To this day, we seem to be surprised to find that as long as it is the field that Huawei is involved in, it can be amazing. Maybe this is the strength and appeal.
As the benchmark for domestic technology companies, Huawei focuses on global competition in terms of R&D investment and development layout, rather than blindly making money. It can even be said that where there is a monopoly, there is Huawei.
Huawei's mobile phones have counterbalanced Apple, the Harmony system has suppressed Android, and Western 5G technology has been stepped on. The special envoy's driverless driving is not worth mentioning in front of Huawei. Nowadays, domestic chips are restricted, and Huawei has made another move. I believe this time , Ren Zhengfei still won't let us down.


28nm chips are sufficient for Huawei's terminal business to achieve complete independence. Although domestic high-precision chip manufacturing has not yet succeeded, a breakthrough will be sooner or later
This is excellent news. This confirms what the Huawei CEO mentioned earlier that Huawei will produce its own 28nm ICs this year.

The completion of the Huawei 28nm Chip production line is very significant.
It means that China has managed to develop an entirely Domestically made 28nm Production Line.
China is entirely self sufficient in production of 28nm ICs.
Next in line will be the Domestic 14nm Production Line.
