At clock position 12 - there is energy-dispersive detector aperture, at 2 - secondary electron detector and bias electrode, and 10 - photomultiplier.

Let's see how other detectors looks like:

Secondary electrons:


Photomultiplier (some components show long cathodoluminescence):

The issue is that while plastic is gone, so does all content of the chip. if you don't zoom too close - it looks like it's a success, die & bondwires are there, but it's a total failure. Alternatively, glass spheres just cover everything and "protect" material below.




Any hints, tips or tricks how to make it work? Or it only works for non-filled plastic?
I am thinking about air assist, oblique angle, increasing spot size (=larger focal distance lens).
