Abstract
1413369 Semi-conductor devices WESTINGHOUSE ELECTRIC CORP 15 Aug 1973 [31 Aug 1972] 39582/73 Heading H1K The blocking voltage of some junctioned semi-conductor devices is stated to be increased without significantly increasing the forward voltage drop by irradiation with electrons having an energy level greater than 1 Mev. at a concentration less than 10<SP>13</SP> electrons cm.<SP>-2</SP>. The level of exposure should not exceed that of 2 Mev electrons at 10<SP>13</SP> electrons cm.<SP>-2</SP>. Devices described are silicon thyristors passivated with silicone or epoxy resins. Specific batches are exposed to 2 Mev. electron radiation at 1.10<SP>12</SP> electrons cm.<SP>-2</SP>, 1.72.10<SP>12</SP> electrons cm.<SP>-2</SP>, and 2.0.10<SP>12</SP> electrons cm.<SP>-2</SP>. Suitable devices for treatment also include transistors but not simple rectifying diodes.
