Abstract
A metal-clad laminate product including a carrier film, a release agent layer, a semi-transparent metal layer and a photo dielectric layer deposited on the conductive metal layer and a method for using the metal-clad laminate product to form an interlayer via by exposing at least a portion of an circuit board intermediate prepared from the metal-clad laminate product to light through the semi-transparent metal layer for a period of time sufficient to form an exposed or an unexposed photo dielectric portion and thereafter removing the exposed or unexposed portion of the photo dielectric layer and a corresponding portion of the semi-transparent metal layer overlying the exposed or unexposed portion of the photo dielectric layer to form an interlayer via.
