As far as Germans inventing the integrated circuit goes? Well that
never happened but it might have because an ex Luftwaffe technician
may actualy have invented a transistor. It's quite a sad story
actualy:

What it describes is interesting but its not a transistor but a cold cathode
tube and that was first demonstrated by Philo Taylor Farnsworth II in 1934

No, the Germans didn't invent the transistor but they did have the
Magnetophon in WW2:

The Germans also had portable tube radios like the Nora K 62:
