The website claims this is used for metrology. It is a light source for mask and optics inspection.
It makes one wonder though. Why make a tool for EUV inspection when you do not have EUV machines in your production line?
Who is supposed to be the target customer for this? Probably not in Russia.

Hefei Research Institute developed BGA chip appearance inspection equipment​

​

Recently, the Bionic Intelligence Center of the Institute of Intelligent Machinery, Hefei Institute of Physical Science, Chinese Academy of Sciences has realized the integration of 3D vision measurement, visual defect detection and other technologies on the self-developed software platform, and solved the problem of Lingjiu GP102, the first domestic GPU in China. Appearance inspection problem. At present, the first BGA chip appearance inspection equipment with independent intellectual property rights has been officially delivered and passed the acceptance.
　　In order to meet the requirements of chip factory quality control and chip traceability, the scientific research team successfully developed the BGA chip appearance inspection equipment A3DOI-BGA with independent intellectual property rights after half a year of product development and testing, which can collect 3D images of chips in batches. Data, plane RGB image data, laser point cloud data, etc., combined with traditional and artificial intelligence algorithms, have achieved the full compliance of various performance indicators such as measurement accuracy and defect recognition rate. The core sensors of the device are all domestically produced, with ultra-high measurement accuracy at the micron level, compatible with a variety of BGA package chip detection, and realize 3D topography measurement of chip finished products.​

Semiconductor laser
The semiconductor industry belongs to the electronic information industry, and the application of laser technology and processing technology in the semiconductor industry has effectively promoted the development of the semiconductor industry. Lasers can be used in the semiconductor industry for laser debonding, wafer laser Dicing, laser annealing, laser marking, laser Flip Chip, and PLP Laser Repair.
The main application of ultraviolet diode pumped solid state (DPSS) lasers in the semiconductor industry is LED wafer dicing. DPSS laser systems are widely used in fields such as micromachining, surface treatment and material processing. DPSS lasers can process sapphire, silicon wafers, III-V semiconductors, III nitrides, ceramics, plastics, and metal materials.
The applications of excimer lasers in the semiconductor industry are mainly 2D pattern forming, 3D micromachining, MEMS micromachining, LED laser stripping, ultraviolet laser lithography and TFT flat panel laser annealing.
Fiber lasers and DPSS lasers are mainly used in the semiconductor industry for thin-film solar cell dicing.
Laser provides effective solutions for the semiconductor industry, and the application of lasers in the semiconductor industry will effectively improve the production quality and output of the semiconductor industry.​

It seems really short-sighted policy by Taiwan to help improving US semi industry. Much more than helping China's, actually. Because even if China closes the gap, Western design firms will keep going to Taiwan, instead if US regains state of the art in foundry, it will attract US firms and Taiwan will lose a lot of geopolitical power. One of the reasons US does not push too much on Taiwan is because a crisis would disrupt the semiconductor supply-chain in the island, and this would have, at this moment in time, a devastating effect on US economy. But when US will be independent from foundry point of view, it could much easily (and I think it will) push on Taiwan tension and trying to create another Ukraine out of it.

@european_guy Ideologue (DPP) had no consciences, when face with a situation instead of reflecting they push thru they had no reverse gear and even willing to sell its Family jewel to prove a point. In my youth I always view conservatism as negative, having ride the tide of Peoples power revolution in 86 and having participated in my early teens, I bask in Liberalism, enjoying the fruits of being free. Well that feeling evaporates immediately as I seen ideologue taking over gov't and messing things up, enriching themselves by selling gov't properties for cheap under the IMF and US DIKTAT. Opponents of the deal are being labeled as Marcos loyalist or worse as communist. that is Liberalism for you a worse kind of Democracy.

And here is another one:

United Microelectronics Corp (UMC, 聯電) yesterday declined to comment on a report that the White House had invited the nation’s second-largest contract chipmaker to build a semiconductor fab in Detroit.

Policy of US is very clear: make US semi firms independent from Taiwan, and which is the most effective, risk free and even cheap way? To force Taiwan firms to set up fabs in US. At that point the fabs will be effectively 100% under US control, and at that point Taiwan will become useless and expandable in a proxy war against China.

It is amazing that Taiwan, that obviusly is able to see it, does not do anyhting, and actually actively contribute to harming itself in the long term.

Hate crime waiting to happen. All these Chinese showing up in a Republican city stealing jobs that belongs to an American that can do it better. China must be putting a gun to the US's head forcing giving these high paying jobs to a bunch heathens.
