ABSTRACT:
A molded tape ball grid array package has a base structure including a heat conductive substrate and flex tape extending from opposing regions on a surface of the substrate with molded plastic material between the flex tape and the substrate. The flex tape has at least one conductive metal lead pattern which can be positioned on a side of the tape facing the substrate with a plurality of apertures exposing the conductive lead pattern from an opposing side of the tape for solder ball bonding. A semiconductor integrated circuit chip is mounted to a central portion of the substrate between the opposing regions of the flex tape with wire bonding interconnecting bond pads on the chip to the metal lead pattern. The chip and wire bonding are then encapsulated on the substrate. The structure is economical and permits high power dissipation from an integrated circuit. The molding process in fabricating the integrated circuit package is economical and readily implemented using injection molding.
