Abstract:
A method for interconnecting bond pads of semiconductor dies or devices with corresponding leads in a lead frame with printed conductive interconnects in lieu of bond wires and an apparatus resulting from the above method. More specifically, some examples include printing an insulating foundation path from bond-pads on a semiconductor die to leads of a lead frame to which the semiconductor die is attached. A foundation conductive trace is printed on top of the insulating foundation path from each bond pad on the die to a corresponding lead of the lead frame. Optionally, on top of the conductive trace, a cover insulating cover layer is applied on exposed portions of the conductive interconnects and the foundation insulating layer. Preferably, this can be the same material as foundation layer to fully adhere and blend into a monolithic structure, rather than separate layers. Optionally, a protective layer is then applied on the resulting apparatus.
