Summary:
  In a breakthrough set to revolutionize the semiconductor industry,
  engineers have developed the world's first-of-its-kind deep-ultraviolet (UVC) microLED display array for lithography machines.
  This enhanced efficiency UVC microLED has showcased the viability of a lowered cost maskless photolithography
  through the provision of adequate light output power density, enabling exposure of photoresist films in a shorter time.

  Now everybody and their cat cam make nano nano chips?
End of ASML?
Go short on them?

ASML offers lithography with a resolution of a couple of nanometres. They use very deep ultra-violet irradiation - wavelength 13.5nm - to get there.

The Nature Photonics paper your puff is based on specifies that their UV
LEDs emit 270nm radiation, twenty times longer, so they aren't in the hunt.
It looks like a useful development, but it isn't going to threaten ASML's market.
