> That said, this tech doesn't look to be sufficient on its own. You probably need to analyze the contents of a chip, not just its structure.
Those two statements appear to be contradictory. Could you clarify what you mean by them and in particular what you mean by the "contents" of a chip ?
I know that low voltage SEM used to be capable of seeing voltage differences in chips but I have no idea if that's still feasible with the scale of today's technology (resolution tends to be worse at lower beam voltages) and the physical basis for flash memory.
- hansvm 4y agoBy "contents" I did mean reading voltage differences. > Contradictory One statement is that if you control a chip you can produce the stated information eventually. The details are an engineering problem. The other statement is that this particular instance of engineering doesn't suffice I don't think. > SEM I'd be inclined to use EFM instead. Its resolution should suffice for the next few generations of chips.
