As an IC failure analysis engineer for many decades at TI, nothing was more impressive than watching a circuit function inside of an SEM. Of course, we never built our own SEM, our old Cambridge S150 came equipped with a electrical feedthrough connector to power the IC. My first experiment was with an old military grade 5400 quad nand gate that definitely had an SiO2 protective overcoat and HF would move the SiO2. A more modern IC would have an silicon nitride overcoat and would resist the HF etch. It would undercut into the SiO2 under the SiN and would eventually lift off the SiN but would destroy the circuit. With your hardware genius, you should build a fluorine based plasma etcher to remove the SiN overcoat.

Apart from your actual discovery, which is like a dream come true for anyone who ever debugged an electronic circuit, what amazes me is that you can just have nitric acid eat away the cover and leave the die perfectly intact, and also that the manufacturers actually print their logo on the silicon.

When I was an undergrad in Cambridge about 1975 I went to some lectures by Prof Bill Beck, who had not only made this work, but had a trick of chopping the electron beam at a frequency slightly below that of the clock to the chip, giving a strobe effect.

Hi Ben :) Love the videos! I think it's more likely the chip killed itself than the e beam - as the vacuum reduced thermal conduction, the chips wires overheated? source: have SEM'd 50 nm silver nanowires without destroying them + killed a few devices before realising thermal conduction in vacuum was the problem.

I remember having to drag an old electron microscope out of mothballs for e-beam probing about 20 years ago. I was ready to throw in the towel when I finally realized the image is the inverse of what I was naively expecting. Instead of higher voltages being associated with brighter metalization, the 5V/3V metal lines were actually darker. Once you realize that and adjust the contrast accordingly, you should even be able to see voltage differences of one or two volts pretty easily....ie. reasonable analog voltage capability. btw this was all without removing passivation from the die. Fascinating video.... I'm sure e-beam probers have much better resolution nowadays but pretty quick way to find out where a chip is broken. Thanks and love all your videos.

In my very early engineering experience as a DPA (destructive parts analysis) engineer at a major aerospace, we did this regularly to add data to the quality control of vendor supplied chips. We would get 32 chips out of a lot of perhaps 250 pieces, and bang them with piezo shock to make the dust dance, decap just like this guy,until removing the oxide he is about to do, and then viewing the chips in an ISI-60 SEM, then X-ray, then rip the silicon and pull the bonds to test strengths, etc

Back in the 1980s I levered the top of some chips (74 series logic and some memory) looked with a powerful optic microscope. As well as the circuit I remember seeing some very small writing on the edge of the chip. These were the ceramic type made of a ceramic and epoxy sandwich. They came apart without too much trouble and reasonably in tact.
