Patent ID: 7314773

Claim:
A method comprising: providing a transparent film comprising a first electrically conductive material, arranged on a transparent substrate; depositing and patterning a mask over the first electrically conductive material, such that openings in the mask have sloping sides which narrow approaching the substrate; depositing a second electrically conductive material directly onto the first electrically conductive material exposed in the openings of the mask, at least partially filling the openings; stripping the mask, leaving behind reentrant structures of the second electrically conductive material which were formed by said depositing in the openings of the mask; after said stripping, depositing a first organic material onto the first electrically conductive material in between the reentrant structures; and depositing a third electrically conductive material over the first organic material deposited in between the reentrant structures, edges of the reentrant structures aligning deposition so that the third electrically conductive material does not directly contact the first and second electrically conductive materials.
