There's no doubt that they're trying. But so far, there are very few working 7nm chips in existence even in labs. Production is extremely difficult. EUV has a wavelength of 13.5nm. 10nm is not exactly easy to produce.

This. I make some of the lasers that produce the plasma that generates the EUV. It is a very difficult process to generate the 13.5 nm EUV. You start with several hundred kW of energy and shooting lasers beams at a tin droplet to generate some EUV, and then capture and direct it to the wafer with as few mirrors as possible, since each mirror reflect only ~80% of the light at 13.5 nm. Also they put these lasers in the basement and UV has to travel up stairs to the fab. Crazy complicated.
