Does the manufacturing of these processors require EUV?
- wmf 6y agoYes, 5 nm and below uses EUV.
- KorfmannArno 6y agoIs there a good and short (5 mins max) video explaining how EUV works and how the produced chip works?
- tedsanders 6y agoIt's 21 minutes, not 5 minutes, but here's a lecture by Chris Mack on EUV from 2013. He's fantastic. (Skip around or increase playspeed if you don't have more than 5 minutes to spare.) https://www.youtube.com/watch?v=LHyV_-9JXu4 https://www.youtube.com/watch?v=LHyV_-9JXu4 Chips produced by EUV work the same as any other chip. And even chips that are made with EUV are only using EUV for the very finest features - they're still using plenty of 'regular' lithography for the dozens of other lithography steps.
- KorfmannArno 6y agoI have way more than 5 minutes, just my attention-span is crippled.
- mastax 6y agoI don't know of a video but I'll try to summarize. How to make a chip: 1. Slice pure silicon into a wafer. 2. Apply a thin coating of a light-activated chemical which does something to the wafer (etch, build up metal, dope[1] silicon, etc.). 3. Shine light through a mask which exposes a pattern into the silicon wafer. 4. Rinse off the un-activated chemical. 5. Repeat steps 2-4 many times for each layer. 6. Slice the wafer up into rectangular chips 7. Package the chips into a plastic, metal, ceramic, package with exposed metal contacts which can be soldered to a circuit board. Why EUV? Extreme Ultraviolet - really small wavelength. When you're trying to expose really small structures you need a really small wavelength. Why is EUV so hard? EUV is extremely high energy so it destroys everything, and it takes a huge amount of energy to create the light source. Also: quantum things.

- tedsanders 6y agoRequire is a very tricky word. But yes, they will be using EUV.
