RADIATION TOLERANCE

Total Dose Radiation Testing

For product procured to guaranteed total dose radiation

levels, each wafer lot will be approved when all sample

devices from each lot pass the total dose radiation test.

The sample devices will be subjected to the total dose

radiation level (Cobalt-60 Source), defined by the ordering

code, and must continue to meet the electrical parameters

specified in the data sheet. Electrical tests, pre and post

irradiation, will be read and recorded.

GEC Plessey Semiconductors can provide radiation

testing compliant with MIL-STD-883 test method 1019,

Ionizing Radiation (Total Dose).
