In built-up multilayers, which start with a traditional core
laminate, subsequent dielectrics are applied in liquid or semi-
liquid state. Unbroken copper areas inhibit cure. Relief is
in the form of "vent" pads appearing as stray anti-pads, or as
a cross-hatch shape.
Sorry that carpal tunnel limits my replies. Or maybe that's a
good thing.
