Patent ID: 8383208

Claim:
A method of fabricating an organic light emitting device, comprising: preparing a substrate comprising: a first electrode, an organic layer comprising at least an emission layer, and a second electrode; placing the substrate in a chamber; preparing a plasma in a cavity of a showerhead in communication with the chamber by injecting an inert gas into a plasma generation region in the cavity and applying power to the cavity; passing a first gas through the plasma; passing the first gas by a heating filament positioned between the showerhead and the substrate, wherein passing the first gas through the plasma and by the heating filament forms a first radical; passing a second gas by the heating filament positioned between the showerhead and the substrate without passing the second gas through the plasma, wherein passing the second gas by the heating filament forms a second radical; and reacting the first and second radicals to form an insulating layer on the second electrode.
