Abstract:
An electrical substrate, comprising:a first conductive layer having an upper surface and a lower surface;a first dielectric layer having an upper surface and a lower surface, said lower surface of said first dielectric layer being attached to said upper surface of said first conductive layer, said first dielectric layer optionally being roughened prior to being attached to said first conductive layer to improve the adhesion between said first dielectric layer and said first conductive layer;a second conductive layer attached to said first dielectric layer and to said first conductive layer through an opening of said first dielectric layer, said second conductive layer having a sidewall;an annealed third conductive layer attached to said second conductive layer including said sidewall of said second conductive layer; anda second dielectric layer formed on exposed surfaces of said annealed third conductive layer and said first dielectric layer, said annealed third conductive layer improving the adhesion between said second dielectric layer and said second conductive layer including said sidewall of said second conductive layer.
