Microscopic is almost underselling it, they're practically at the atomic level at this point

almost? Blue light can resolve around 450nm. What process node are we on again? 5nm?

EUV is done by a laser going through a droplet of tin. as per ASML site:
In our laser-produced plasma (LPP) source, molten tin droplets of around 25 microns in diameter are ejected from a generator at 70 meters per second. As they fall, the droplets are hit first by a low-intensity laser pulse that flattens them into a pancake shape. Then a more powerful laser pulse vaporizes the flattened droplet to create a plasma that emits EUV light. To produce enough light to manufacture microchips, this process is repeated 50,000 times every second.

2nm process is the current one from TSMC, but it's more a marketing term.
