I'm thinking lithography. The higher the DPI the smaller you can make your components.

SLA printers would definitely benefit, provided these tiny LEDs can put out the required UV.

Maybe for low end lithography, you can't use normal light for anything high end, already at 7nm it requires EXTREME ultra violet. And the lamps for that cost 100s of millions, to make the shortwave light necessary.

But for low end, it could possibly be used for ultra fast and cheap cycle between tape-out and production?
