Radio frequency identification (RFID) tags and processes for manufacturing
the same. The RFID device generally includes (1) a metal antenna and/or
inductor; (2) a dielectric layer thereon, to support and insulate
integrated circuitry from the metal antenna and/or inductor; (3) a
plurality of diodes and a plurality of transistors on the dielectric
layer, the diodes having at least one layer in common with the
transistors; and (4) a plurality of capacitors in electrical
communication with the metal antenna and/or inductor and at least some of
the diodes, the plurality of capacitors having at least one layer in
common with the plurality of diodes and/or with contacts to the diodes
and transistors. The method preferably integrates liquid
silicon-containing ink deposition into a cost effective, integrated
manufacturing process for the manufacture of RFID circuits. Furthermore,
the present RFID tags generally provide higher performance (e.g.,
improved electrical characteristics) as compared to tags containing
organic electronic devices.
