Abstract:
A method for forming a high density multi-chip module, comprising:providing a plurality of integrated circuit semiconductor dice, each semiconductor die of said plurality having an active surface having a plurality of bond pads thereon; forming a substrate with opposing first and second sides, at least three elongate through-slots extending from said first side to said second side; forming a pattern of a plurality of electrical conductors associated with said substrate on each of said first side and second side of said substrate, at least one electrical conductor of said plurality of electrical conductors having a connection terminal adjacent a through-slot of said at least three elongate through-slots for connecting said plurality of bond pads of a semiconductor die of said plurality of semiconductor dice to an input/output connector; connecting said pattern of a plurality of electrical conductors on said first side and said second side of said substrate with conductive vias through said substrate; forming an input/output connector on said substrate and connecting said input/output connector to said plurality of electrical conductors, said forming an input/output connector comprising forming a ball-grid-array on one of said first and second sides of said substrate in a peripheral area surrounding said plurality of semiconductor dice; attaching the active surfaces of a plurality of said plurality of semiconductor dice to the first side of said substrate wherein the bond pads thereof are aligned with alternate through-slots of said at least three elongate through-slots for access from the second side of said substrate; attaching the active surface of at least one semiconductor die of said plurality of semiconductor dice to said second side of said substrate, the plurality of bond pads of said at least one semiconductor die aligned with other alternate through-slots of said at least three elongate through-slots for access from the first side of said substrate; wire-bonding said plurality of bond pads of each attached semiconductor die of said plurality of semiconductor dice to connection terminals adjacent the alternate through-slots; and inserting a flowable, hardenable glob-top material into each of said through-slots to encapsulate wires therein, such that said glob-top material extends outwardly toward at least one edge of at least one semiconductor dice adjacent said slot, thereby contacting said at least one edge.
