Going down further, metal-3 is half gone. Here is what metal-2 and below looks like. Vias are again clearly identifiable.

Now, that one's done imaging and stitching. I've lapped it down to remove the rest of this metal layer already, imaging it comes next... Can already tell the top array is EEPROM/Flash. A couple more memories appear to be in the bottom as well.

@infosecdj I remember when they first succeeded getting copper on a die. What metal are most of the chips your stripping using?
