Conversion process for passivating short circuit current paths in electronic devices having a metallic electrode

摘要

An electronic device of the type including a thin film body having a superposed metallic electrode has short circuit defects therein passivated by a conversion process in which the electrical resistivity of the metallic electrode material is increased proximate the defect regions. Conversion is accomplished by exposing the metallic electrode material to a conversion reagent and activating the reagent proximate the defect regions. The process may be utilized for a variety of differently configured devices, and may be readily adapted for use in a roll-to-roll device fabrication process.
