摘要： An opto-electronic device includes: (1) a substrate; (2) a nucleation inhibiting coating covering a first region of the substrate; and (3) a conductive coating including a first portion and a second portion. The first portion of the conductive coating covers a second region of the substrate, the second portion of the conductive coating partially overlaps the nucleation inhibiting coating, and the second portion of the conductive coating is spaced from the nucleation inhibiting coating by a gap.
