Abstract:
1. An electrical interconnect structure for interconnecting with at least one integrated circuit die, the electrical interconnect structure comprising: a conductive core having first and second sides, the first side including first and second surfaces arranged in a stairstep relationship to each other, wherein the first surface is a conductive surface; a first aperture extending through the conductive core from the first surface to the second side, the first aperture having a conductive circumferential wall; a second aperture extending through the conductive core from the second surface to the second side; a first signal path extending through the first aperture and having an end adapted to connect to an integrated circuit device, wherein the first signal path is electrically conductive; a second signal path extending through the second aperture, and; a first insulating member disposed within the first aperture to electrically insulate the first signal path from the conductive circumferential wall of the first aperture.
