Abstract:
A method of forming a molded semiconductor package comprising:(a) forming a slot in a substrate, the substrate having a first surface and a second surface; (b) covering one end of the slot on the first surface of the substrate with a material; (c) attaching a semiconductor device to the first surface of the substrate such that the semiconductor device is adjacent to the material and covers a portion of the slot; (d) electrically coupling the semiconductor device to the substrate; (e) providing a mold, the mold having an inlet gate at an edge of the mold for introduction of a molding compound; (f) suspending the semiconductor package within the mold; and (g) flowing the molding compound into the mold such that it first flows around the semiconductor device and then flows through an opening at an opposing end of the slot from the first surface of the substrate to the second surface of the substrate to form a molded semiconductor package.
