Abstract

This invention generally relates to organic electronic devices and to methods for their fabrication. More particularly we will describe organic thin film transistor (TFT) structures and their fabrication.An organic electronic device, the device comprising: a substrate supporting a first electrode; a spacer structure over said substrate; a second electrode over said spacer structure and at a height above said first electrode; and a layer of organic semiconducting material over said first and second electrodes to provide a conducting channel between said first and second electrodes; and wherein a majority of said first electrode is laterally positioned to one side of said channel and a majority of said second electrode is laterally positioned to the other side of said channel.
