Abstract

PURPOSE:To obtain the switching characteristics suitable for the oscillation booster, by making easy the control of turn off time, through the radiation of gamma rays, to the symmetrical switch of PNPNP five layer construction formed with P type Si substrate. CONSTITUTION:The N type layers 2 and 3 are formed by diffusion on the both sides of the P type Si substrate 1 being the base region, and the peripheral parts 40 and 50 of the PN junctions 4 and 5 produced at this time are made deeper slightly than those at the center. Next, the P type regions 6 and 7 are formed by diffusion at the surface of the layers 2 and 3, producing the PN junctions 8 and 9, and the first electrode is attached by bridging the regions 2 and 6 and the second electrode 11 by bridging the regions 3 and 7. After that, the end exposed is protected with the glass films 16 and 17, constituting the symmetrical switch. Further, gamma rays of 5 X 10<6> to 5 X 10<7>R is radiated to the switch thus assembled, adjusting the turn off time. The turn off time is too longer with the dose less than 5 X 10<6>R and no effect to improvement even with excess of 5 X 10<7>R.
