Patent ID: 7752752

Claim:
A method of fabricating a substrate comprising: forming a first conductive layer on a dielectric layer; forming a resist layer on the first conductive layer; forming laser-ablated artifacts through the first resist layer, through the first conductive layer, and at least partially into the dielectric layer, wherein the first conductive layer is exposed within the laser-ablated artifacts; forming a second conductive layer on the resist layer and within the laser-ablated artifacts, the second conductive layer being electrically coupled to the first conductive layer; selectively removing a portion of the second conductive layer such that the second conductive layer remains only within the laser-ablated artifacts; subsequent to the selectively removing a portion of the second conductive layer, filling the laser-ablated artifacts to form an overfilled circuit pattern; removing the resist layer; and selectively removing the first conductive layer and a portion of the overfilled circuit pattern to form an embedded circuit pattern, the embedded circuit pattern being embedded within the dielectric layer.
