Abstract

We have successfully fabricated organic thin-film transistors (OTFTs) on plastic substrates by the printing process. The semiconductor of the OTFT was defined by inkjet printing. The poor consistency of the printing patterns has made high uniformity of the OTFTs more difficult to achieve. Thus, a basic unit of circuits called a transistor array with redundant transistors was designed and fabricated. In addition, we proposed a method to increase the circuit yield by incorporating a pre-testing step during circuit fabrication. These devices were then connected via printed nano-silver to each other to form a subcircuit called a gate. To verify the design flow, we measured the bootstrap inverters based on the transistor arrays. A ring oscillator was fabricated in a similar methodology based on the gate array.
