Patent ID: 7189593

Claim:
A method of fabricating a semiconductor device, comprising the steps of: providing a flexible film interposer, the interposer comprising a first surface and a second surface; an elongate slot formed through and along a peripheral edge of the interposer to expose bond pads on a second semiconductor die mounted onto the second surface of the interposer; a plurality of spaced apart recesses formed through the interposer and adjacent the slot, each recess having a base; and a plurality of conductive traces on the second surface of the interposer, each trace extending across and exposed through the slot and the base of one or more adjacent recesses in a perpendicular orientation to the slot; and mounting a first semiconductor die on the first surface of the flexible film interposer; the first semiconductor die having a first active surface and a second surface, the active surface comprising a plurality of spaced apart conductive connecting members; the first semiconductor die mounted on the interposer such that a conductive connecting member of the die is received in a recess of the interposer in conductive contact with the trace at the base of the recess.
