Appeal No. 2000-0038
Application 08/751,369
THE INVENTION
The appellants’ claimed invention is directed toward a
process for making an optical waveguide. Claim 10 is
illustrative:
10. A process for the production of an optical waveguide,
comprising the steps of:
(a) shaping a substrate consisting essentially of organic
material only;
(b) applying at least one intermediate layer by a vacuum
coating process, onto the substrate; and
(c) applying a waveguide layer by means of a reactive
physical vapor deposition (PVD) process, onto the intermediate
layer, the reactive physical vapor deposition process being
reactive DC sputtering.
