That’s a Big Microscope…

I’ve often said that there are no secrets in hardware — you just need a bigger, better microscope.

I think I’ve found the limit to that statement. To give you an idea, here’s the “lightbulb” that powers the microscope:

It’s the size of a building, and it’s the Swiss Light Source. Actually, not all of that building is dedicated to this microscope, just one beamline of an X-ray synchrotron capable of producing photons at an energy of 6.5keV (X-rays) at a flux of close to a billion coherent photons per second — but still, it’s a big light bulb. It might be a while before you see one of these popping up in a hacker’s garage…err, hangar…somewhere.

The result? One can image, in 3-D and “non-destructively” (e.g., without having to delayer or etch away dielectrics), chips down to a resolution of 14.6nm.

That’s a pretty neat trick if you’re trying to reverse engineer modern silicon.

You can read the full article at Nature (“High Resolution non-destructive three-dimensional imaging of integrated circuits” by Mirko Holler et al). I’m a paying subscriber to Nature so I’m supposed to have access to the article, but at the moment, their paywall is throwing a null pointer exception. Once the paywall is fixed you can buy a copy of the article to read, but in the meantime, SciHub seems more reliable.

You get what you pay for, right?

    Correction: You don’t get what you don’t pay for.

    If you want even larger systems, you should check out the European XFEL, which was just opened, and is now the most powerful free electron laser in existence.
    It’s quite a sight.

    So cool!
