- Abstract
High voltage 4H-SiC Ti schottky junction barrier schottky (JBS) diode with breakdown voltage of 1200 V and forward current of 40 A has been fabricated. A low reverse leakage current below 1.02 × 10-4 A or 4.08 × 10-4 A/cm2 at the 25 and the reverse bias voltage of 1200 V has been obtained. The forward on-state current was 40 A at VF = 1.61 V with 25 and at VF = 1.89 V with 100 . The chip is 5 mm × 5 mm and the active-region is 3.8 mm × 3.8 mm. The turn-on voltage is about 0.83 V. The on-state resistance is 4 m •cm2. The doping and thickness of the N-type drift layer and the device structure have been performed by numerical simulations. The SiC JBS devices have been fabricated and the processes were in detail. By using Ti/Ni/Au multilayer metal structure, the double side Au process of 4H-SiC JBS diode is formed.
