Abstract:
1. A method for depositing a patterning material onto an optically transparent substrate, wherein the optically transparent substrate includes a back surface and a receiving surface, said method comprising: placing a solid layer of patterning material substantially adjacent to the receiving surface of the substrate, wherein the solid layer includes a first surface facing the receiving surface and a second surface facing away from the receiving surface; directing a focused laser beam at an incident angle between 0 and 90° relative to the receiving surface and through the back surface; and depositing patterning material from the first surface of the solid layer onto the receiving surface of the optically transparent substrate by transmitting the laser beam through the optically transparent substrate onto the solid layer to cause the patterning material from the first surface of the solid layer to evaporate and become deposited onto the receiving surface.
