Why? What prevents you from illuminating the whole chip with electrons? Can't get an electron source "bright" enough? Uniform enough? The chip can't handle

Why? What prevents you from illuminating the whole chip with electrons? Can't get an electron source "bright" enough? Uniform enough? The chip can't handle that much current? Or what?
- adgjlsfhk1 2y agoThe problem is that you can't make mirrors or lenses for electrons, so the mask can't be bigger than the chip. There's also the significant problem that shooting electrons at things tends to damage them, so making a mask that can survive the process sounds very tricky.
