Abstract:
A method for manufacturing a workpiece comprising placing a substrate which has a first and a second mutually opposite surface and a dielectric material body on a first electrode surface within a vacuum coating chamber, thereby exposing said second surface to said vacuum coating chamber and completely covering said electrode surface with said dielectric, material body, inletting a reactive gas into said vacuum coating chamber by coupling Rf energy into said vacuum coating chamber via said first electrode and through said dielectric base body and through a second electrode in said vacuum coating chamber, thereby generating a plasma between said second surface and said second electrode, coating said substrate by plasma-enhanced chemical vapor deposition thereby reacting said reactive gas introduced into said vacuum coating chamber by way of said plasma generated by said Rf energy, and exploiting said second surface as an electrode surface exposed to said vacuum coating chamber.
