Abstract:
1. A method for the manufacture of an array-type package for encasing one or more semiconductor devices comprising the steps of: a) providing a heat slug array containing a dielectric substrate with a plurality of apertures and a plurality of interconnected heat slugs having opposing first and second portions separated by a mid-portion that extends through one of said plurality of apertures wherein said first portion has a perimeter larger than the perimeter of said one of said plurality of apertures, multiple tie bars projecting from said perimeter wherein a tie bar from one said heat slug intersects at least one other tie bar from an adjacent heat slug at an interconnection point; b) bonding said one or more semiconductor devices to said first portion and electrically interconnecting said one or more semiconductor devices to electrically conductive vias on a first side of said dielectric substrate, said electrically conductive vias extending through said dielectric substrate to an opposing second side thereof; c) providing an array of heat spreaders having multiple tie bars extending from a perimeter thereof wherein a tie bar from one said heat spreader intersects at least one other tie bar from an adjacent heat spreader at an interconnection point; d) bonding tie bars of said heat slugs to tie bars of said heat spreader such that said one or more semiconductor devices are disposed between one of said heat slugs and one of said heat spreaders; e) encapsulating said one or more semiconductor devices and at least a portion of said heat spreaders and heat slugs in a molding resin; and singulating the array into individual components.
