Backyard semiconductor production is pretty similar to backyard barbecue. Lots of heating, smoking (diffusion), injecting (ion implant), and layering..
With enough sauce, the end result won’t even taste like chewing on a rock. :-)

#143Great video, very much has NileRed vibes.

#144I saw this video yesterday and considered posting it, but I wasn’t sure if it was appropriate for HN. This channel has another video where it shows how the clean room lab is created starting from a basic backyard shed, and that was truly astounding. The positive pressure to keep the number of particles low in someone’s backyard is almost mystical to me.
You’re not sure if someone building a RAM clean room in a shed is appropriate for HackerNews, literally “news for nerds”? A dictionary purchase may be warranted

If you haven't seen this one, I highly recommend it: Indistinguishable From Magic: Manufacturing Modern Computer Chips https://www.youtube.com/watch?v=NGFhc8R_uO4&t=2070s It's quite old but I think there is no modern version of it. I've tried posting to HN a few times but it hasn't gained traction for some reason, but I find it absolutely mind blowing.
Videos in general don’t get much traction here. Most of the time I don’t want to watch them in this context either, when other sites I do. Maybe it’s just I come here for the old web feel when video was costly, rare and short.
There's something to it. I personally am happy to have one of these few precious places left where I can find content to read rather than watch.

> Does this look normal to have locked videos behind a paywall then have it public and free elsewhere? Yes, this is very normal on youtube with both patreon and nebula.
Well that's the first time I encounter this. I have been using Patreon for years and typically a creator who locks content even often mention "Please do not share outside". It's also often hosted on YouTube but usually unlisted. Can you please give me an example of locked content that is openly shared outside? I guess I don't understand the monetization in that situation so I'd appreciate if you could help me get wha…
The pattern I often see is a Patreon release a week before the public release.

Video links are naturally gonna get less clicks from people scrolling HN at work :)

#148I'm not sure this is what they meant when they said they wanted to bring manufacturing back to the USA lol
Jokes aside, seeing as this person has created their own clean room in a shed, and is making RAM, what exactly is stopping any company from doing this themselves and breaking into the RAM business? I'd pay less for RAM that wasn't "certified" in some official way, at least it works.
EUV lithography is the state of the art. It makes far denser chips and is quite out of reach for the backyard fellow. Find a documentary on how ASML machines work: they're near the pinnacle of human accomplishment!

Re: Making RAM at Home [video]
#149Incredible video! I've been in tech for 20 years but never really bothered to dive in to the process of making RAM. This is eye-opening and makes me appreciate the sophistication of the tech involved in making those ram-sticks.
Re: Making RAM at Home [video]
#150This is fascinating, but it really highlights how insane modern hardware manufacturing has become.
Would be interesting to know where the biggest bottleneck shows up first: materials, lithography, or error rates?
