An electrochemical processing method is provided for forming a current carrying device for semiconductor chip packaging and similar applications. The method comprises selecting sections of a substrate to carry current wherein a selected section is at least partly covered with a voltage switchable dielectric material, rendering the voltage switchable dielectric material conductive, and electrochemically forming a current carrying material directly on the voltage switchable dielectric material. The voltage switchable dielectric material can have a characteristic voltage, such that when a voltage having a magnitude exceeding the characteristic voltage is applied to the voltage switchable dielectric material, the voltage switchable dielectric material switches from a dielectric material to a conductive material. When conductive, the voltage switchable dielectric material is amenable to electrochemical processing such as electroplating.
