Just watched one of my weekly doses of tech and this was
incredible, The vid starts off abit low tech but skip to min. 18, it's from
Dave and his EEVblog 532 - Silicon Chip Wafer Fab Mailbag . don't know about
his comment at 38 minutes 10, about the pin holes, LED lights maybe? and just a
side note, it is in English but Dave takes a bit of getting use to AND is
brilliant.

I reckon Wilson would even appreciate the scale of this.
Watched that one time before, but the 100nm probe tip always blows me away.
Doesn't give too much info, but unless you are in the nanoE field or are studying a degree for it, you won't find all too much on it in video format. I do love how these chips are manufactured. The architecture design is probably the most important but, the fabrication process is insane. Extruding the silicon crystal, slicing it up, oxidizing the wafer (Dry or Wet @ an upwards of 1200C or TEOS deposition), Photo-resist, lithography, Etching, ect. My favorite machine that I use though is the most basic of them all. It washes the HF off of the wafers. The name is why I love it though - The Superclean 2000 Such an evil scientist name.
Also, since LEDs, were mentioned. Quantum wells, are pretty awesome. Working with a sapphire wafer and indium, you create these quantum wells that are what actually emit the light. This is true with LEDs in general. I've only actually done it with theory and the materials above.
In Russia, Tip blows you!
sorry couldn't resist
That was super interesting! Thanks for the link.
Are there any good documentaries or videos that someone could recommend that details the whole fabrication process?
I have a general idea of how cpu's are made but i'd love a more technical and in depth explanation.
This is kind of short video to explain such a complex process but its a decent one
It's hard to find. I wish I knew of one when people asked why I spend my life in a cleanroom. I know of either theory videos that try and quantify a particular concept, or basic intro videos like the GF that @Theonewhoisdrunk posted. Generally, you need to find someone who is in the field and is willing to try and give you an understanding.
If Tek Syndicate would reach out to places like Intel, GF, AMD, ect, I think they could potentially give some good videos on this topic. Very technical and that is the type of audience we are for the most part.
