Is it? Looks like this video is "locked" on Patreon requiring "this post and more exclusive work. Join for $10/month" yet got, as of now, 329 611 views ... so are they just making $3M/month or is it not really working?
You can go to their Patreon and see that they are making CAD545/month [1] [1] https://www.patreon.com/cw/DrSemiconductor

I visited a pcb making factory once. Left with an appreciation for the amount of work needed for 80-layer pcbs, and knowing I would not want to deal with making them myself.
my goal was simple 2 sided pcbs, machined traces because i wanted to avoid chemical etching, but when it comes to via's chemicals are really the only way. The chemcials needed for plating via's are very toxic. my current thinking to avoid the really nasty ones is to try conductive ink (probably pretty bad too) but it maybe would work to coat the fr4 material and then allow a copper plating to take... really it's a fu…

HF is routinely used in analytical labs; it's standard to microwave HF solutions for ICP digestions. It's not even the most hazardous reagent in my lab right now. Now, perhaps this chemist meant that no chemist in their right mind would physically touch HF--in that case, I agree completely!
AFAIK they're talking about anhydrous HF gas, not solutions of it. That sounds substantially less fun to work with. It's used to clean CVD chambers.

In one of Dwarkesh's interviews, he mentioned that China is trying to replicate the entire stack. Ironically now that they have mastered all pieces of the stack for older nodes, they actually have an advantage in a collapse scenario. The US does not appear to have the ability to do all steps in the stack for any node. They still rely on other western countries that could go offline. China despite being behind does at…
Lucky for America, in the case of civilizational collapse there will be a lot of spare semiconductors thanks to almost everyone being dead!

It is not really feasible to fabricate usable integrated circuits at home. There is a huge difference between a one off demonstration of a principle that "sort of works", and perfecting the process to the point that it produces finished parts that can be relied on. This guy is not exactly a regular person. He is a pretty unique case of a talented semiconductor engineer who has a home lab for side hassles. It is not a…
"Side hassles"... hahaha. Love it.
