Publication number: 20030209752Abstract: A low programming power, high speed EEPROM device is disclosed which is adapted for large scale integration. The device comprises a body, a source, a drain, and it has means for injecting a programming current into the body. The hot carriers from the body enter the floating gate with much higher efficiency than channel current carriers are capable of doing. The drain current of this device is controlled by the body bias. The device is built on an insulator, with a bottom common plate, and a top side body. These features make the device ideal for SOI and thin film technologies.Type: ApplicationFiled: May 10, 2002Publication date: November 13, 2003Inventors: Jin Cai, Tak Hung Ning

Patent number: 6437422Abstract: 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.Type: GrantFiled: May 9, 2001Date of Patent: August 20, 2002Assignee: International Business Machines CorporationInventors: Paul M.
