  • Method of treating SiPOS passivated high voltage semiconductor device
    Patent number: 4297149
    Abstract: The breakdown voltage of high voltage semiconductor devices passivated with SiPOS deteriorates if the devices are allowed to soak at temperatures in the 400.degree. C. to 525.degree. C. range. The original breakdown voltage is recovered by annealing the devices at a temperature of above about 550.degree. C. prior to metallization and alloying the metal at less than 425.degree. C.
