There are three things here that you've intertwined.

Process -- This is the science of creating circuits on silicon wafers using lithography, etching, and doping. There is a large body of knowledge around the physics involved here. Materials science and Physics and Silicon Fabrication are all good places to start.

Chip Design -- This is creating circuits which are run through a tool that can lay them out for you automatically. HDLs teach you to describe the semantics of the hardware in such a way that a tool can infer actual circuits. Generally a solid understanding of digital logic design is a pre-requisite, and then you can learn the more intimate details of timing closure, or floor planning, signal propagation and tradeoffs of density and speed.

IP -- Clearly all of the intellectual property law is a huge body but most of the IP around chips is patent law (how the chips are made) and copyright law (how they are laid out).

Yes that's true, but there's actually even more like packaging, testing, etc. I took a free online course from Stanford called "nanomanufacturing" but it really was mostly about about chip manufacturing, packaging etc. Even though I worked in the semiconductor industry for 12 years (mostly bench testing preproduction ASICS) I still found it really useful. Not sure if you can still view the archives here if you sign up for an account (I can but I took the class)

No substitute for learning the physics, but at least it kind of gives you some idea of what's involved. In addition to all the crazy technology involved in fabricating the chips, the packaging technology has gotten really sophisticated. It can be very confusing about what's the difference BGA, WLCSP, stacked dies, etc. Anyway the course covered a lot different types of processing with examples.

That is awesome. The link doesn't work for me but I didn't really expect it to. My first job in the Bay Area was working for Intel and about 6 months in I was offered some 'counterfeit' or grey market Intel DRAM chips. (as a microcomputer enthusiast, not as an Intel employee) I took the offer to security, who gave me the cash to buy a tube of them, which I did, and they disassembled them to figure out where in the packaging pipeline they had gone missing.

Sadly I never got to hear the full story on how they came to be but I did get a good look at the packaging pipeline that Intel used at the time. It was extensive even then with half a dozen entities providing steps in the path.
