It looks like they had that in mind while they were designing it: "But our lenses, being planar, can be fabricated in the same foundries that make computer chips. So all of a sudden the factories that make integrated circuits can make our lenses." If this is true, I imagine old foundries could produce these since they probably don't need anything near the precision or consistency that current-gen chips require.
