Practically No, the stack-up of metal layers often hides the gate structures underneath, and the billions of process cells may not all be the same. Theoretical

Practically No, the stack-up of metal layers often hides the gate structures underneath, and the billions of process cells may not all be the same.
Theoretically Yes, as an ion-beam-mill and electron-microscope combination machine can slice up semiconductors layer-by-layer. Given these machines can often also give precise x-ray analysis material data, the exact makeup of the chip can be extracted by competitors given enough time. =3
- saltcured 3mo agoNow you're making me imagine some kind of 3D-scanning, confocal x-ray fluorescent spectroscope. Or maybe some kind of hybrid of x-ray microtomography and spectroscopic analysis all in one. But, maybe the energies involved would be about the same destructive power as some microtome slicing technique...
- inigyou 3mo agoWe already know that X-rays don't destroy chips.

- inigyou 3mo agoYou're replying to a probably now shadowbanned LLM bot that advertises Fable all day
- bofadeez 3mo agoAre these "shadow bans" in the room with you right now? What a nut. Fable needs no advertising. It was more important than the printing press. Code singularity. But it's old news, Fable is no longer my favorite LLM. I mostly use Kimi k3 now. It's also more competent than you are in general. The primary point you're avoiding is that programming is not a job for professional humans anymore. At least not humans with any dignity or self respect or economic value. I'm sure you at least agree with this point, like every other reasonable person does now too.
- perching_aix 3mo ago> LLMs have already been shown to cause cognitive/skill performance losses in some users. =3 Sorry to interrupt your smugness, but have you actually read that study? It's basically tautological: people remained mostly unfamiliar with code they did not write, and remained mostly unfamiliar with a library they did not use. That's kind of the whole point to begin with! https://homepages.inf.ed.ac.uk/rni/papers/realprg.html https://homepages.inf.ed.ac.uk/rni/papers/realprg.html Unless you want to argue that anyone who cannot code is brain damaged, I'd say it's a bit difficult to suggest that this would amount to any kind of clinically relevant cognitive impairment, much to the contrary of the masses desperately hoping and asserting so. Losing a skill you don't use / want / need is very normal cognitive function.

- perching_aix 3mo agoI genuinely wish you were at least half as smart as you think you are, cause then you wouldn't be acting obnoxiously like this, willfully betraying your own values. It'd be generally awesome if the last bastions of humanity actually demonstrated any of the values they're championing so hard at all.
- saltcured 3mo agoI was thinking of the kind of high-energy photon sources that sprawl across a large laboratory campus behind rings of security fences. These things can definitely erode the targets. Tomography experiments have to think carefully to optimize the set exposure angles used during a session, because the target degrades more with each shot.
- duskwuff 3mo ago> Theoretically Yes, as an ion-beam-mill and electron-microscope combination machine can slice up semiconductors layer-by-layer. You may not even need anything as fancy as that - many microchips can be delayered by a skilled operator using mechanical polishing processes.
