Abstract

Disclosed embodiments include a catalyst-doped mold interconnect system, where activated catalyst particles that line via and trace corridors, are used for electroless-plating formation of both liners and vias and traces that also electrolessly plate onto the liners. Photolithographically formed interconnects can be mingled with laser-ablation form-factor vias and traces within a single stratum of a catalyst doped mold interconnect system.
