Patent ID: 7501071

Claim:
A method of producing a patterned mirror on a transparent conductive substrate comprising the steps of: coating a layer of conductive material onto a 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 the layer of photoresist through a first mask to produce a desired pattern of transparent conductors on the layer of photoresist; developing the layer of photoresist; simultaneously etching the layer of the conductive material and the layer of metal to transfer the desired pattern of transparent conductors to the layer of conductive material, thereby forming transparent conductors; exposing portions of the layer of photoresist that remain through a second mask to produce a desired pattern of metal conductors on remaining portions of the layer of photoresist; and developing the remaining portions of the layer of photoresist and etching the layer of metal to transfer the desired pattern of metal conductors to the layer of metal, thereby forming metal conductors.
