Im sure the million dollar waffer machine that are required to make the CPUs will come with instructions. Also dont forget about the antistatic, antidust, better then hospital steralization rooms arent cheap either. If you want to make some CPU's I hope you got some really, really deep pockets.
Oh if this is for some sort of research project I would check both intel and AMD's sight. They might have so info about them in the developer part of their sites.
I used to be into necrophilia and bestiality, but then I realized I was just beating a dead horse.
