Abstract
Active devices that have either a thread or a ribbon geometry. The thread geometry includes single thread active devices and multiple thread devices. Single thread devices have a central core that may contain different materials depending upon whether the active device is responsive to electrical, light, mechanical, heat, or chemical energy. Single thread active devices include FETs, electro-optical devices, stress transducers, and the like. The active devices include a semiconductor body that for the single thread devices is a layer about the core of the thread. For the multiple thread devices, the semiconductor body is either a layer on one or more of the threads or an elongated body disposed between two of the threads. For example, a FET is formed of three threads, one of which carries a gate insulator layer and a semiconductor layer and the other two of which are electrically conductive and serve as the source and drain. The substrates or threads are preferably flexible and can be formed in a fabric.
