An organic thin film transistor (TFT) of circular geometry is constructed by the use of polymer-based substrate, insulator, and semiconductor. Owing to the plasticity of organic materials, this device is mechanically molded by pressing the central circular drain electrode. A shallow well is created, resulting in the localization of the transistor channel onto the wall of the well. The electrical characteristics of the transistor remain almost unchanged after this molding. The obtained vertical device architecture allows the use of a very large channel width over length ratio, while preserving a maximum drain electrode area to be devoted to the further deposition of liquid crystal or an electroluminescent film. Current output of the order of some milliamperes per square centimeter can be delivered, which makes these molded TFTs well adapted for the construction of display pixels. © 1998 American Institute of Physics.
