Hi, genious duo, I had an old US Army report that emphasizes a lot about irradiation of semiconductors. Now, you have to make a distinction between cleaning semiconductors and expose them to natural irradiation as ready products. UV/O2 is a outstanding method of cleaning any substrates, inclusive semiconductor wafers of all kinds, because you get a cleanliness on molecular level. And under controlled processes, the method does not cause any harm to the target. About semi packages and irradiation, I understand what Juice aim at, namely a exposure to high energy partikels or photons or phonons at such a intensity level that you exceed the band gap levels , equal to a memory I/O status shift. I believe modern packages and semis are radiation hardened for critical applications like for SPACE and others. If you, of some reason, want to clean assembled boards by means of UV/Ozone, nothing will happen. You can take part of the report under 'Cleaning' and the title is 'UV-Ozone Cleaning of Semiconductor Surfaces'. Steve, you are welcome to add your antique papers to Dropbox. As I said, most was evaluated decades ago.
