They did some of the engineering behind the fundamental tech but later dissociated from it, then later didn't invest in buying and integrating it (EUV machines) when it was on the verge of production and missed out. I believe their first in-house fabbed chips with EUV only released within the last month or so, Meteor Lake. It takes ~3 years to stand up a fab and has only been 5-6 since EUV was proved out with first mass production.
