Abstract: A method of fabricating a packaging substrate is disclosed. A cladding sheet comprised of a first metal foil, a second metal foil and an etch stop layer interposed between the first and second metal foils is provided. The first metal foil is then patterned into a first circuit trace. An insulating layer is laminated onto the first circuit trace. Thereafter, the second metal foil is patterned into a plurality of bump pads. The etch stop layer that is not covered by the bump pads is stripped off. A solder mask is applied to fill the spacing between the bump pads. A top surface of each of the bump pads is etched to form a bonding aperture in a self-aligned fashion.

Abstract: In a dual-sided chip package without a die pad according to the invention, a first die can be fixed directly on the lead fingers of a leadframe, a support bar, or bus bars, while a second die is attached to the first die. Without a die pad, the distance between the surfaces of the dies and the plastic surface of the package therefore gets longer. Thus, the invention enables a large decrease in the probability of generating voids in the plastic and there is no need to grind the dies. Besides, it improves the vibration and floating characteristics of the dies in the manufacturing process and thus prevents the exposure of the bonding wires and the shelling off or breaking of the dies. The invention can raise the yield of chip packages.

Abstract translation: 在根据本发明的没有芯片焊盘的双面芯片封装中，第一裸片可以直接固定在引线框架，支撑杆或汇流条的引线上，而第二裸片附接到第一裸片。 没有管芯焊盘，因此，模具表面与封装的塑料表面之间的距离变长。 因此，本发明能够大大降低在塑料中产生空隙的可能性，并且不需要研磨模具。 此外，在制造过程中，提高了模具的振动和浮动特性，防止了接合线的暴露和模具脱壳或断裂。 本发明可以提高芯片封装的产量。
