Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

They moved TSMC production facilities to Phoenix, Arizona. It's slated to open in 2025.
They didn't move them, they're just building new fabrication plants here so we don't have to depend on threatened foreign land for the production. https://pr.tsmc.com/english/news/2977
Also SMIC (China's chip manufacturer) is now also producing 7nm chips, even though they were sanctioned in 2020. That means they either had a breakthrough in the process or they obtained and were able to repair and operate/reverse engineer the incredibly complex TSMC fabs.
7nm doesn't need EUV, as things get smaller it doesn't suddenly become impossible to do things with traditional lithography it just becomes harder and at some point incredibly uneconomical. They certainly ripped off the node from TSMC in some way (whether spionage or reverse-engineering), that is, the shape of the transistors and stuff but that doesn't mean that they're producing them in the same way.
Thank God they're finally building some chip plants here. The fact that our whole economy depends on some foreign island next to a huge country that has always hustorically threatened to take it back is insane to me. Although I think we should have more manufacturing in the homeland in general. Thanks capitalism, for off shoring manufacturing for the last many decades -_-
TSMC is just the end of a long supply chain of one-of-a-kind suppliers, all conveniently aligned with the West. TSMC does not make the lithography machines, the Dutch ASML is the only company that does (though they have some plants in the US now I think). Even so, ASML would be dead in the water without Swiss Zeiss optics.
The US' strength was never autarky, but global trade. The reason the US economy is so resilient is because most US dollars are not in the US, but in reserves across the world. That means even the US currency is intertwined with global trade. If the US attempted autarky, it would collapse both the US and the world economy. That's why Trump's policies were beyond stupid by the way.
Zeiss is German. The Semiconductor supply plant is in Oberkochen.
It’s a pretty interesting story where Taiwan decided to invest enormously into chip production so they could use the economic benefits to shield themselves from China. Worked pretty well eh
It was a gamble to focus on fabrication only and not include design. It payed off but it was a gamble.
Except they have problems finding workers. 3rd world Americans aren't cut out for the jobs it seems like.
I think it's mostly because it's in Arizona... Not exactly the tech capital of the U.S..
They wanted somewhere where land and labor was cheap and neglected to consider educated engineers and water are vital for a semiconductor fab to operate.
It was a fucking stupid decision, and TSMC has been flying in Taiwanese engineers and workers in general to make up for the short comings.
