Cathode separators typically used for patterning metal cathodes of organic light‐emitting diodes (OLEDs)—see Figure—can be fabricated using a lithography‐based technique that allows the construction of reversely tapered 3D structures in one single molding step. The physics involved in making the fabrication of such 3D structures possible is outlined and the efficacy of the separator thus fabricated is demonstrated with an OLED.
