GeneralRe: processor transistor layout Pin

At my former workplace, some of the pictures on the wall were microphotographs of the company's former chip generations, based on the 8051 architecture developed in 1980. You could easily identify rectangular areas with a regular, quite fine-grained structure: the memory banks. Other areas were more irregular; those were the CPU. Some areas with almost no identifiable structure, more like 'spotty'; that was the various I/O devices (this was an embedded type chip, with lots of I/O beyond the CPU capabilities); you could even identify a couple coils - the chip I/O included a radio.

So you could identify various areas, but it just looked like different kinds of structures, more or less regular or irregular. Seeing the shape of individual components was not possible, at least not on these wall posters.

I am talking about 40+ years old 8-bit technology (or rather: architecture), approx. 50,000 transistors for the CPU. Even with that simple chips, you wouldn't get what you are asking for. Today's 64 bit processors are extremely more dense, and complex, approaching 50 billon transistors. You will probably see "gray" areas that are likely to be the cache memory. If pointed out to you, you can probably distinguish a few other functional areas from the rest, but all you can see is that they are different from, and less regular than, the cache areas.

For the simple question of "what does a so-and-so type transistor really look like?", you can probably find 3D engineering drawings, similar to that of a MOSFET in the Wikipedia article "Transistor". But those are drawings, not the chip photographs you are asking for.
