Maybe I'm missing something here. This looked like it would be good, but I only got as far as the second page.

It claims to be aimed at "curious people over the age of 14", but goes from "the period at the end of this sentence is a million nanometers", straight to diagrams filled with nothing but technical jargon.

The text has various unexplained terms throughout, that are mentioned as if the reader already knows them: "PDK", "stackup", "layer", "polyres", "polysilicon" and "gate of a MOSFET" for example.

"Mask" is explained, and it's a good explanation. It'd be great if that attention was given to other domain-specific terms someone coming to this new likely doesn't know, or maybe has seen but doesn't know well or in this context.
