NON-ABLATIVE LASER PATTERNING

摘要

A method for processing a transparent substrate includes generating at least one laser pulse having laser parameters selected for non-ablatively changing a conductive layer disposed on the transparent substrate into a non-conductive feature, and directing the pulse to said conductive layer. A protective film may be affixed to a surface of the transparent substrate and need not be removed during the processing of the substrate. After processing, processed areas can be visually indistinguishable from unprocessed areas.
