This isn't a lithography process in the way you're probably thinking. Electron beams are very slow. So while they're useful for making certain kinds of prototypes and other low volume items, they're useless for mass production.
Also, the west has had this capability for a long time. Indeed, 72nm patterns aren't very special.

I think visible tattoos are ugly and I'd never get one... But 72nm is an invisible tattoo...
You're right, I am just salty.

it has nothing to do with the 7nm nodes on silicone wafers, that's correct
