Abstract
A micro filled material includes a binding material and optionally includes a number of particles. The binding material and the particles can be formed of any conductive or nonconductive material. Using such a micro filled via material, an electrical conductor is formed in a substrate for supporting one or more electronic components using the following steps: placing the micro filled via material between two conductive layers at various locations in a substrate at which an electrical conductor is to be formed; and optionally programming the micro filled via material to reduce the resistance of, or to form an electrical conductor.
