Electroconductive Support, OLED Incorporating It, and Manufacture of Same

A method of forming an electroconductive support comprising:

• forming a patterned masking layer over a first layer having a primary surface, wherein the patterned masking layer includes an opening;
• etching a cavity in the first layer below the opening such that a zone of the patterned masking layer is suspended over the cavity;
• depositing a conductive material within the cavity using a wet chemical deposition;
• and
• removing the patterned masking layer to form a conductive strand within the cavity, wherein the conductive strand has a side zone and a central zone, the side zone is defined by a portion of the conductive strand that was covered by the zone of the patterned masking layer, and the central zone was under the opening in the patterned masking layer when depositing the conductive material;
• and
• forming an electroconductive layer overlying the conductive strand and the first layer, wherein the electroconductive layer contacts the first layer and the conductive strand along the upper surface of the conductive strand within the side zone.

• forming a passivation layer over the conductive strand;
• selectively exposing the passivation layer to radiation, wherein the conductive strand acts as a masking layer, such that part of the passivation layer overlying the conductive strand is not exposed to the radiation;
• and
• removing an exposed portion of the passivation layer and leaving a remaining portion of the passivation layer.
