Abstract

A system includes a device having at least one integrated circuit. The integrated circuit further includes a first layer of conductive material, a second layer of conductive material, and a via having multiple electrical paths for interconnecting the first layer of conductive material and the second layer of conductive material. A method for forming a via includes drilling an opening to a depth to expose a first pad and a second pad, lining the opening with a conductive material, and insulating a first portion of the lining in the opening from a second portion of the lining in the opening to form a first electrical path contacting the first pad and a second electrical path contacting the second pad.
