Abstract :
A hybrid mode of device operation, in which both bipolar and MOSFET currents flow simultaneously, has been experimentally investigated using quarter-micrometer-channel-length MOSFET´s which were fabricated on SIMOX silicon-on-insulator substrates. This mode of device operation is achieved by connecting the gate of a non-fully-depleted SOI MOSFET to the edges of its floating body. Both the maximum G/sub m/ and current drive at 1.5* higher than the MOSFET´s normal mode. Bipolar-junction-transistor (BJT)-like 60-mV/decade turn-off behavior is also achieved. This mode of operation is very promising for low-voltage, low-power, very-high-speed logic as well as for on-chip analog functions.<>
