Abstract
An opto-electronic device includes: a first electrode; an organic layer disposed over the first electrode; a nucleation promoting coating disposed over the organic layer; a nucleation inhibiting coating covering a first region of the opto-electronic device; and a conductive coating covering a second region of the opto-electronic device.
Claims46
A device having a plurality of layers, extending substantially transverse to a lateral aspect of the device, the lateral aspect comprising a first region and a second region, wherein the layers comprise:
- a substrate extending across the first region and the second region;
- and
- a conductive coating supported by the substrate and disposed along the second region only;
- wherein the conductive coating is formed by actions comprising:
- depositing a nucleation inhibiting coating on the substrate along the first region only;
- and
- subjecting the substrate and the nucleation inhibiting coating to a vapor flux of a conductive coating material for which the nucleation inhibiting coating has a low initial sticking probability, so that the conductive coating forms primarily where the substrate is substantially devoid of the nucleation inhibiting coating.
