Still used and very useful for test and debug; I worked with Kleindeik Nanotechnik on the process for the Pi 5's little SoC and learned a lot on the way; a little in this blog post but more in the video I linked in it: https://www.jeffgeerling.com/blog/2024/die-shots-and-transistor-level-debugging-on-raspberry-pi-5 https://www.jeffgeerling.com/blog/2024/die-shots-and-transis... der8auer on YouTube also did an even more in depth video on the nanoprobing, at least, and there are a couple places showing the process of etching with electron beam, but not with a very good explanation.
