I really hope I can one day afford a microscope like a TEM so I can do cool imaging of chip dies.
From a security perspective I would feel like it might help us find more flaws in the silicon that create these security nightmares.
From a purely honest perspective..... I'm amazed at how complex modern chips and the packaging have become. It feels like black magic, but I don't want to call it that cuz it feels like I'm overlooking the insane talent and labor that goes into making these things feasible
- SJC_Hacker 2y agoI haven't worked with STEMs before, but with Two photon and confocal setups. My bet is everything around the microscope is probably going to cost as much as, possibly even more the microscope itself. E.g., a good optics bench will set you back several thousand, and they are extremely heavy. STEMs also typically operate in a vacuum at very low temperatures approaching absolute zero, so you will some liquid nitro handy to cool your sample as well as a way to pump all the air out.
