Abstract:
1. A semiconductor die assembly comprising: a first semiconductor die having an active surface, an opposing back side and a side extending transversely therebetween; a plurality of bond pads over the active surface in a first arrangement; and a flexible dielectric interposer substrate having first and second opposing sides and first and second adjacent portions laterally separated by a spacer portion; and the first portion including a first plurality of electrical contacts on the first side thereof connected to substantially all the bond pads of the plurality and communicating through conductive traces with at least a second plurality of electrical contacts on the second side of the second portion in a second arrangement different from the first arrangement, said flexible dielectric interposer further including a third plurality of electrical contacts on the second side of the first portion in a third arrangement different from the first arrangement and in communication with at least one of the first plurality of electrical contacts and the second plurality of electrical contacts through conductive traces; wherein substantially all of the first portion of the interposer substrate extends and is secured over the active surface of the first semiconductor die, substantially all of the second portion is secured over the back side thereof and the spacer portion extends over the side thereof.
