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.
