>neviksti had a lot of these techniques down, and some better/safer ones (etchant sand to expose the mask ROM better ... someone mentioned it in the video), but I don't think he had a microprobe station. That seems like a very nice idea for when a FIB workstation is waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay out of your price range.

Didn't Dr. Decap mention micro-probing at some point?

Sure Xray works, but not everyone has an Xray machine.

That's why you have to be nice to your dentist. ;)

Are xrays good enough to distinguish separate layers though? And especially where the vias are connected?


You guys do know that theres such a thing as a Portable Package Scanner? They've become really hot since 9/11, and many safe and vault techs use them to manipulate safes open (since you can see where the gates are). They're only 6 grand.

Theres a really interesting story about how the KGB and our CIA were in a battle of technology for manipulating safes open (submarines have safes with launch codes and crypto stuff in them). We put ball bearings in and the KGB came up with image processing techniques to get around them and then we'd add more ball bearings and lead shields. Finally, we just made the wheels out of plastic and it worked.

That sounds really interesting, but all I can find are simple ones that are basically metal detectors, nothing more. Mind posting a link?

Only 6K? I'll take a dozen! :)

I've never used one of those, so I'm not sure how they compare to the ones I've worked with. The kind of images I'm used to seeing are like this: http://4.bp.blogspot.com/-kkFlM6bcORo/T ... tal-02.jpg (not my picture)
