Abstract :
A novel power rectifier structure called the injection controllable Schottky barrier (ICOS) rectifier is proposed and studied by two-dimensional device simulation. The ICOS rectifier can operate in the bipolar mode to reduce the on-state voltage and can start operating in the unipolar mode just before the reverse-recovery stage to reduce the reverse-recovery current. For high-current-density application, it is found that complete unipolar operation for the ICOS rectifier requires fine pattern fabrication technology. The device can realize low on-state voltage and low reverse-recovery current. For higher current density, the ICOS rectifier can have a soft-recovery characteristic with low reserve-recovery current
