Patent ID: 8222727

Claim:
An interposer device, comprising: a substrate having a first side and a second side opposite the first side; a plurality of conductive sections arranged in a first predetermined pattern on the substrate, the individual conductive sections including a first section at the first side of the substrate and a second section at the second side, wherein the second sections of the individual conductive sections at the second side of the substrate extend outboard of the corresponding first sections on the substrate; a plurality of passages selectively formed through a number of the conductive sections in a predetermined second pattern corresponding to a desired arrangement of conductive lines on the substrate, wherein at least some of the conductive sections do not include passages; and a plurality of conductive lines arranged in the second pattern on and/or in the substrate, the individual lines including an electrically conductive fill material deposited into the passages to form interconnects electrically coupling the first sections to corresponding second sections, and wherein the conductive lines at the first side of the substrate are positioned to be directly electrically coupled to corresponding connectors on a microelectronic die to which the substrate will be attached.
