What Goes On Inside a Semiconductor Wafer Fab

As a physicist and aviation tech inspector, I have to say: chapeau bas!
My deepest respect for translating these processes to the masses.

I've watched a lot of videos on top of a lot of my own research as fabs have found themselves so incredibly complex. That being said, this video checked all the boxes and is such an awesome resource of information in one place. A banger as always!

I have been in the semiconductor industry for 25 years, and I have to say that this video is one of the best layman's explanations of what goes on in the fab I have seen. I'm going to share this with anyone who asks what I do for a living.

I also liked the nod to Arthur Miller.

you've just described most of my working life in 21 and half minutes! Good job!

i think he likes semiconductors but idk

One special mention for the metrology and the defectivity control tools also. Important, if not fundamental throughout all these complex steps!

This was a great video! As an engineer responsible for lithography in our cleanroom, I’d like to add that after exposing photoresist (and usually after performing the post exposure bake) the waters are bathed / sprayed with chemicals called “developers”. Basically like developing photos from camera’s before the digital age. This development is an important factor in controlling the critical dimensions (CD) of patterns in the resist. You’re essentially dissolving part of the resist to open it up for etching after all! Looking forward to future videos about plasma tools, there’s a lot of fascinating physics involved in both deposition and etching.

I would love to see a video on the next step in the process, the science and application of packaging, testing, and binning.

This is an excellent tutorial on what is a hugely complex process in an even more complex industry

Came across your channel maybe 2 years ago. I am now working in tool installation at a big semiconductor company in the US. My hope is to go to college and one day learn how to use the factories I am helping to build. The more information I have the more valuable I become. For someone who has been a little too specialized in the industry this all around video is very helpful. Thank you so much!!!

16:00 - awwwhhh.... you missed the coolest part of that process! It doesn't 'just eventually happen'. It waits until the place is struck with a cosmic ray passing through and igniting the plasma.

Yes, we literally set the thing up and wait for the universe to start the process for us.

This channel deserves subscribers in the millions. It really is incredible content.

[PeculiarNotions]

I always appreciate that you got jokes. Even if you did the whole video for that joke at the start, it'd be worth it, and I'd watch the whole thing.

I'm in awe at the complexity and precision of the processes presented.

Just a slight change in presentation style and I would easily think this was all sci-fi techno babble.

Seeing all these steps that go into making a silicon chip makes you realize the marvel a silicon chip really is.

Just think of all the silicon chips that over the decades were thrown out and ended up in landfills (broken computers, electronic toys with chips in them, outdated washers and dryers, junk cars with chips to regulate fuel consumption and smog control, etc.) Its like throwing away top of the line Swiss watches.

Amazing channel. I'm liking the humor you're starting to introduce as well, makes it even more engaging and enjoyable to watch, almost reminds me of Patrick Boyle with his mixture of dry humor and legit analysis of a complex topic

[punditgi]

Amazing channel with top notch videos. Always learn a ton every time. We sure appreciate chips a lot more than most of us used to. 😊🎉

Great video, it’s difficult to cover the full scale of a fab in a short video, but you did a nice job.

One minor correction at 17:32. A planar MOSFET drain and source will both be doped the same (N or P type), not differently, while the channel will have the opposite doping. When voltage is applied to the gate an inversion layer is created in the channel that allows the FET to conduct.

[frederikvanstolk]

Two minor corrections:

* The source and drain are both doped with either n-type or p-type impurities. It is the channel below the gate that gets doped with impurities of the opposite types.
* It's pronounced an-isotropic, not anise-o-tropic.

Thankyou so much for this. I know nothing about semiconductors and this was a great overview of their manufacturing that was straightforward and easy to understand even for someone like me. Awesome job.
