It's not just Infineon - it's called the European Semiconductor Manufacturing Company (ESMC) and is a joint venture by TSMC, Bosch, Infineon, and NXP, with TSMC being the majority (70%) shareholder.
I've met one of the engineers designing the piping for that plant. Hardest project to date for him and mainly because TSMC was setting the pace.

Apparently there are.
>Looks inside
>It's all TSMC
They can't even come up with an original name, they just replaced Taiwan with European.
I can imagine their pace might be accelerated but better than endless discussions, shuffling and never shipping
> The company ... sought to capitalise on the massive AI investment boom
These chips are probably very useful and important, but I don't see what they have to do with AI. Does everything need to have the word AI these days?
That reality is carefully left unclear in all this "silicon sovereignty" narrative. It's a nice plant with new tooling cranking out 300mm wafers, but it's not the same game as a TSMC or Intel fab making cutting edge, high margin silicon, and there are a number of competitors making similar power devices around the world. And yes, the "AI" fluff is pure marketing nonsense; everyone needs lots of power devices for everything.
Not directly. This fab is meant to primarily fabricate compound semiconductors which is Infineon's niche and is a major bottleneck for European industry today.
> Does everything need to have the word AI these days
Because Infineon's press release [0] for their compound semiconductor fab called out "AI".
Additonally, the "semiconductor" and "hardware" segment has now been rebranded has "AI" in a number of funds. By calling out something that's even tenuously tied to "AI", it allows funds that are contractually tied to investing in "AI" to purchase Infineon stock.
Investor relations is important as well.

You might not be able to fabricate billion terraflop GPUs but at least the basics of survival will be able to be locally produced without scavenging washing machines for parts.
The (western) economy runs on sub 7nm phone, laptop and datacenter chips on which the white collar workforce produces value. Those are the ones that are also the most profitable since they have the highest margins. Europe doesn't have that.
Yes, the cutting edge is very nice, but any laptop past 2016 is useable for the average person. Even gpu inference on older process nodes is perfectly doable. The HPC space absolutely prefers newer chips but hasn't ripped out their 2018 chips in their clusters because they still deliver value.
And sure, the latest best things sells for higher margins for now, but with the way consumer prices are going, people may start choosing older still perfectly capable models that cost less.
The greater danger to a working economy is not absence of the absolute must cutting edge chips but lack of independence which this initiative seems to seek to curtail. Good for Germany.

One could say they have an even bigger real world impact.
We can vibecode SaaS junk that we will have all forgotten about this time next year at never-before-seen speed, but every single day, hundreds or thousands of times a day, you brush up against something that was built by an AB or Siemens PLC installed in 2004 that might be slated for decommissioning in a decade or so.
I don't like this framing.
These aren't logic ICs but that doesn't mean they are useless or "easy".
Heck, the only countries with Gallium Nitride fabrication capabilities and knowhow are the US, China, Taiwan, Japan, South Korea, Germany, and India.
In fact, compound semiconductors and power electronics is one segment where Europe's China dependency is extremely high, as they have significant uses from automotive to PLCs to weapons systems, and China has already begun embargoing the EU's access to rare earth elements [0] and has begun enforcing sanctions against the EU's aerospace and UAV industry [1].
These are dual use technologies and a major reason why both the US and China heavily invested in compound semiconductor capacity in the late 2010s and early 2020s.
Edit: can't reply
> In 2024 Belgium closed its only semi fab, which had recently pivoted to GaN
THEMA Foundries is working in photonics, not GaNs [2]. The GaN initiative (BelGaN) failed and the only two buyers interested in buying out the property for GaN fabrication were a Chinese and Indian player [2].

So basically all major industrial powers? In which case I don't get the use of the world "only" here, as if the EU, the richest block in the world, deserve praise for doing something countries a lot less wealthier are doing.
> and China has already begun embargoing the EU's access to rare earth elements [0] and has begun enforcing sanctions against the EU's aerospace and UAV industry [1].
The way it's framed it sounds like China is some evil bad guy for doing that but that's standard practice that the EU and US also do. The EU also restricts ASML EUV machines to China and sanctions Chinese tech in their defense sector. Standard stuff.
ASEAN doesn't have the capacity yet, but this is changing in 3-5 years as Malaysia, Singapore, Vietnam have gotten IP transfers from European, Korean and Japanese technology partners.
Neither does the rest of the Europe excluding an Ireland-UK-UAE JV called ChipX (but the team is largely located in the US, UAE, Malaysia, and Japan) and the portion of STMicro in France that was part of state-owned Thomson Semiconducteurs before it was privatized.
Neither do any of the major industrial states in the Americas like Canada, Mexico, or Brazil.
> that's standard practice that the EU and US also do
My point is that states need to build domestic capacity where possible. And the EU is not a state. France continued to protect their GaN fabrication IP closely (not even sharing it with Italy despite STMicro being a French-Italian JV), and same with Germany to a certain extent.
[1]They need to use US EDA tools, And manufacture masks but maybe there are tricks they won't need to trust them - like inspecting critical parts of the masks.
Design capacity doesn't imply fabrication capacity, as can be seen with Israel and India's comparative dominance in the chip design industry.
Design capacity (basically programming and logic design) is orthogonal to front-end fabrication (basically material science and chemical engineering) which is orthogonal to back-end/OSAT (basically materials science and metrology).
Only the US and Taiwan have domestic E2E capacity in all 3.
This is not directly related to AI or logical compute, so kvetching about GPUs, SoCs, TSMC, AI, and other buzzwords is dumb.
EU has FTAs with Japan and SK, and others that dominate the segment like Taiwan, China, Thailand, Malaysia, Vietnam, and India have already unlocked public-private subsidized for the sector.
Additionally, the big players in the industry like ZDT, Unimicron, Nippon Mekatron, Foxconn, Compeq, TTM, and Flex have much stronger financial and political linkages in Asia or the Americas.
This fab itself is important, but was extremely difficult to stand-up and was largely a result of the supply chain issues that the automotive industry faced during zero covid, so it basically took 6 years to execute on this project. That lag-time is the biggest issue unless individual European states decide to take industrial policy their own hands, which becomes expensive very quickly.
Concentrating on building a niche in compound semiconductors as well as 2.5/3D packaging would probably be the best bet for the EU today, but I expect to see French-German industrial rivalry to undermine coordination.
Infineon got €1bn of tax payer money to open the plant (~$1.1bn).
