Abstract

See full text

A method for forming a structure for a radio frequency identification device includes dispensing a photosensitive compound onto a substrate. Subsequently, first portions of the photosensitive compound are exposed to a light pattern from a light source, while second portions of the photosensitive compound remain unexposed to the light source. Exposing the photosensitive compound to light reduces the photosensitive compound to a metal layer. The unexposed second portions of the photosensitive compound may be rinsed away to leave the metal layer. Processing may continue to form an RFID circuit from the metal layer, and a completed RFID transponder comprising the RFID circuit.
