A Novel Depletion-IMOS (DIMOS) Device With Improved Reliability and Reduced Operating Voltage

We experimentally demonstrate a novel depletion-IMOS (DIMOS) device with a 12.1-mV/dec subthreshold slope and 5-decade ON/OFF ratio, employing a depletion mode of operation instead of inversion. DIMOS structure improves reliability by reducing hot carrier injection and features 40% lower breakdown voltages with higher ON currents compared to conventional IMOS.
