#2If you wire up a solar cell like an LED, it glows dimly in infrared. QA uses this to diagnose dysfunctional wafers.

#3Fun fact: Solar cells and the LEDs are the same element. If you wire up a solar cell like an LED, it glows dimly in infrared. QA uses this to diagnose dysfunctional wafers.

Steve Mould had a video[1] about this a couple of years ago where he shows a small solar panel lighting up. [1]: https://www.youtube.com/watch?v=6WGKz2sUa0w

#8I used to be a professional computer geek on weekdays and professional photographer on weekends; and 20 years on, it still blows my mind the similarities between the materials and manufacturing of the CPU doing heavy work in my laptop and the sensor gathering pixels in my camera :O
E.g. EPROM (memory type chip) is typically deleted by shining a uv light on the actual silicon die, through a uv transparent quartz window in the final packaged chip.
edit: fixed EEPROM -> EPROM

Also, EPROMs are extremely vintage. They were replaced by EEPROMs - the first of which came out in 1977. That's an... extremely vintage example.
