We fabricated one-dimensional Plastic Retina structures by depositing gold strips onto glass substrates, and subsequently applying thin layers of conducting materials onto this pattern. The materials that were studied consisted of both conducting polymers which were spin cast and inorganic semiconductors. In all cases the thin film structures yielded results that were in accordance with theoretical predictions. The test structures were used to quantify the material sheet resistance uniformity and long-term stability. Additionally, we have synthesized several varieties of conducting polymer systems, including new PANI derivatives and Mends. The ultimate goal of this effort was to create conducting polymer systems that have lower conductivity and higher film uniformity. This class of materials is essential to the operation of the Plastic Retina structures currently being fabricated by UNIAX under a joint BMDODARPA program. For the Plastic Retina, or the Thin Film Analog Image Processor TAIP, a sheet resistance greater than 10exp 5 omegasquare is required. Furthermore, the TAIP requires a highly uniform 5 PANI thickness across the surface of the chip. UNIAX has achieved this goal, and successfully fabricated new polymer systems that provide lower conductivities with high film uniformity.
