Confidently incorrect about how fragile some circuits can be. Simple functionality is a convenient illusion we've beaten into various squiggles of metal. Electricity is secretly also a radio and a magnet, and even in wires it can't know there's nothing at the end until it gets there. Sometimes things just happen.
They're fabricating micrometer components with a 90 nm process. That's pretty well in the classical regime. If they're seeing substantial tunneling at that scale it would be rather noteworthy to say the least.
It's not tunneling, it's capacitance. Even truly disconnected components can accidentally become a transformer.
A single diode a micrometer away from anything else is not suddenly a transformer without which a 400 um^2^ antenna stops working.
