There are less dangerous ways to explore "building a CPU from scratch" that hit on the really interesting bits. "Digital Computer Electronics" by Malvino and Brown. You are given logic gates (and, or, nor, nand etc) and build up from there to a working CPU. The articles referenced about HF are terrifying. I am a programmer, but, have worked in a chemistry lap. Its just endless stinky stuff that will kill you in a variety of ways. The logic of how a CPU works is more interesting.

Maybe for you. I find silicon fabrication to be much more interesting.
