First Claim
Patent Images
1. A process to apply a heater function onto a plastic glass substrate comprising the steps of:
- inserting the plastic glass substrate into a sputtering process chamber;
cleaning the surface of the substrate by a dry etching step;
preparing a copper target in a pre step;
sputtering copper onto the surface;
removing the layered substrate form the sputtering process chamber; and
inscribing tracks onto the layered surface with a laser beam.
