Abstract:
A permeation barrier film structure for organic electronic devices includes one or more bilayers having a hybrid permeation barrier composition. Each of the one or more bilayers includes a first region having a first composition corresponding to a first CF4—O2 Plasma Reactive Ion Etch Rate and a second region having a second composition corresponding to a second CF4—O2 Plasma Reactive Ion Etch Rate, wherein the second Etch Rate is greater than the first Etch Rate by a factor greater than 1.2 and the hybrid permeation barrier film is a homogeneous mixture of a polymeric material and a non-polymeric material, wherein the mixture is created from a single precursor material.
