Die photos and analysis of the revolutionary 8008 microprocessor (2016)

Dice?

Looking at one of the labeled diagrams [0], it looks like all the large areas of polysilicon are either serpentine structures that are probably resistors, or they're adjacent to one of the power rails. The ones you're referring to seem to be at the top of the instruction register section and right below the Vdd (-9V) line. So we may simply be looking at larger transistors to handle more current and voltage.

I know slightly less than nothing about this topic, but I remember reading this from a while back:

"Notes for reversers Electron holes have more effective mass, and therefore less mobility. P-type regions are thus made bigger than N-type regions to compensate. The size disparity often differentiates P-type and N-type silicon."

Maybe that is helpful...?

The "extra" polysilicon region is a capacitor made of silicon and polysilicon. These capacitors were a "bootstrap load", essentially a way to drive a transistor harder to get a stronger output. The capacitors you're looking at are for the instruction register to drive the signals through the instruction decoder (basically a PLA). Since the decoder is fairly large, the signals into it need to be boosted. I haven't looked at this for several years, so I may be wrong about some of this.

Nah not enough spaghetti

maybe the cpu in a sd card?
