摘要
A method of forming a wafer level package includes attaching a laser-activated dielectric material to an integrated circuit substrate to form an assembly, the integrated circuit substrate including a plurality of electronic components having terminals on first surfaces thereof. The laser-activated dielectric material is laser activated and ablated with a laser to form laser-ablated artifacts in the laser-activated dielectric material and simultaneously to form an electrically conductive laser-activated layer lining the laser-ablated artifacts. The laser-ablated artifacts are filled using an electroless plating process in which an electrically conductive filler material is selectively plated on the laser-activated layer to form an embedded circuit pattern within the laser-activated dielectric material.
