Patent ID: 6884658

Claim:
A method of assembling a printed circuit board, said method comprising: providing a substrate including a first surface and conductive contacts included on said first surface; providing a first semiconductor die including a pair of major surfaces, wherein one of said pair of major surfaces of said first die defines a first active surface, the other of said major surfaces of said first die defines a first stacking surface, and said first active surface includes a plurality of conductive bond pads; electrically coupling said first active surface to said substrate with a plurality of topographic contacts extending from respective conductive bond pads on said first active surface to corresponding conductive contacts on said first surface of said substrate; providing a second semiconductor die including a pair of major surfaces, wherein one of said pair of major surfaces of said second die defines a second active surface, the other of said major surfaces of said second die defines a second stacking surface, said second active surface includes a plurality of conductive bond pads, and said first stacking surface is devoid of conductive bond pads; securing said first stacking surface to said second stacking surface; securing a single decoupling capacitor to said second active surface; providing a pair of conductive lines, each of said conductive lines connecting a terminal of said decoupling capacitor, a bond pad on said second active surface, and a conductive contact on said first surface of said substrate; electrically coupling said conductive contact on said first surface of said substrate to said first semiconductor die via one of said plurality of topographic contacts extending from respective conductive bond pads on said first active surface to corresponding conductive contacts on said first surface of said substrate; arranging said pair of conductive lines such that said decoupling capacitor is connected across V ss and V cc pins of said first and second semiconductor dies; positioning a printed circuit board such that a first surface of said printed circuit board faces said substrate; and providing a plurality of topographic contacts extending from said substrate to said first surface of said printed circuit board.
