Abstract
The present invention relates to a method for forming a raised conductive image on a non-conductive or dielectric surface, the method comprising placing a metal coordination complex on a surface of the substrate, exposing the surface to electromagnetic radiation, reducing the exposed complex. removing unexposed complex leaving an elemental metal image, removing unexposed metal complex and then plating the resulting elemental metal image with a highly conductive material.
Claims31
A method of forming a layer of conductive material on a substrate surface, the method comprising:
- activating at least a portion of the substrate surface;
- depositing a metal coordination complex on a part of the activated portion of the surface;
- applying a magnetic field to the metal coordination complex that is located on part of the activated portion of the substrate surface to align molecules of the metal coordination complex with the magnetic field;
- exposing the metal coordination complex to electromagnetic radiation;
- reducing the metal coordination complex to elemental metal;
- removing unreduced metal coordination complex from the surface;
- drying the surface;
- and
- depositing a conductive material onto the surface;
- wherein the magnetic field is removed prior to the depositing the conductive material onto the surface.
A method of fabricating a substrate, the method comprising the steps of:
- activating at least a portion of the substrate surface;
- depositing a metal coordination complex on a part of the activated portion of the surface;
- applying a magnetic field to the metal coordination complex that is location on part of the activated portion of the substrate surface to align molecules of the metal coordination complex with the magnetic field;
- exposing the metal coordination complex to electromagnetic radiation after the applying;
- reducing the metal coordination complex to elemental metal after the exposing;
- removing unreduced metal coordination complex from the surface.
