摘要

First recovery SOI diodes have been developed for 500V 1A 1 chip inverter IC application, adopting reduced emitter efficiency. Since lifetime control process is not adopted the diode fabrication process is completely compatible with those of conventional LSIs. It was found that the ruggedness depends on the anode structure. The largest current ocntrollability was achieved for the diodes, where the anode emitter ocnsistes of merged p-schottky and p+ ohmic contact and, for the cathode emitter, p+ diffusions are formed in the n-type cathode layer. The developed 1A rated diode controls 4 ampere current and achieves 300nsec reverse recovery time under the condition of 13A/mivs di/dt and 300V applied voltage.
