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 method 1019 Ionizing
Radiation (total dose) test.
