ABSTRACT:
A method of producing a relief structure on a patterned conductor comprises the steps of; coating a layer of conductive material onto a transparent substrate, coating a layer of metal onto the layer of conductive material, coating a layer of photoresist onto the layer of metal, curing the layer of photoresist, exposing a desired pattern of transparent conductors through a first mask onto the layer of photoresist, developing the photoresist and simultaneously etching the layer of the conductive material and the layer of metal, exposing a desired pattern of metal conductors through a second mask onto the remaining layer of photoresist, developing the photoresist and etching the layer of metal, applying a further layer of photoresist, curing the further layer of photoresist, exposing the further layer of photoresist thorough the substrate, developing the photoresist and allowing the layer to dry, resulting in a pattern of spacers/reliefs in registration with the metal conductors.
