Recently developed normally-off transistor named GIT (Gate Injection Transistor) and novel passivation technique using poly-AlN to uniform the surface temperature will be reviewed. We have developed a normally-off AlGaN/GaN transistor using conductivity modulation named GIT (Gate Injection Transistor). This new device principle utilizes hole-injection from p-AlGaN to AlGaN/GaN hetero-junction which increases electron density in the depleted channel resulting in dramatic increase of the drain current owing to the conductivity modulation. The fabricated GIT on Si substrate exhibits the threshold voltage of +1.0V with high maximum drain current of 200mA/mm. The obtained on-state resistance and off-state breakdown voltage are 2.6mohm•cm2 and 640V, respectively. |
