Polyimide is used as an insulating layer in the fabrication of multilayer electronic circuitry. Generally, a first layer of circuitry is fabricated on a substrate, a layer of polyimide is applied over the first layer of circuitry and then a second layer of circuitry is fabricated on top of the polyimide. Interconnection between the layers is achieved by means of vias that etched in the polyimide.
