Overview and Background
Among other radiation effects, Total Ionizing Dose (TID) may affect electrical characteristics,
causing parametric and/or functional failures in integrated circuits. During gamma-irradiations,
TID-induced and transported electron-hole pairs may result in charge trapping in a transistor’s
dielectrics and interface regions, affecting the device’s basic features. Such effects warrant testing
and monitoring of circuits to TID, after which annealing and/or Time Dependent Effects (TDE)
may take place, depending on the circuit’s design and process technology. Hence the requirement
per Condition D (for low-dose rates ranging from less than or equal to 10 mrads(Si)/sec) in
TM1019, MIL-STD-883 is to not exceed the allowed time of one hour from the end of an
incremented irradiation and an electrical test. Additionally, the total time from the end of one
incremental irradiation to the start of the next incremental step should be less than two hours.

Radiation Facility and Test Equipment
The samples were irradiated at Defense Micro-Electronics Activity (DMEA) facility in Sacramento,
California. DMEA utilizes J.L. Shepherd model 81-22/484 to provide the dose-rate of 10
mrads(Si)/s. A special design screw-driven automatic cart inside the exposure tunnel positions
the Device-Under-Test (DUT) precisely and repeatedly from the source to attain optimal rate
verified by ion chamber detectors. See Appendix C for the certificate of dosimetry.

Test Conditions
The 10 samples were placed in a lead/aluminum container and aligned with the radiation source,
Cobalt-60, at DMEA facility in Sacramento, California. During irradiation, five units were biased at
+/- 15V and other five had all pads grounded. The devices were irradiated up to 50 Krad(Si) with
increments of 10, 22, 31 Krads(Si). After each irradiation, the samples were transported in dry ice
to Linear Technology testing facility. Testing was performed on the two control units to confirm
the operation of the test system prior to the electrical testing of the 12 units (10 irradiated and 2
control).
The criteria to pass the low dose-rate test is that five samples irradiated under electrical bias must
pass the datasheet limits. If any of the tested parameters of these five units do not meet the
required limits then a failure-analysis of the part should be conducted and if valid the lot will be
scrapped.

Test Results
All ten samples passed the post-irradiation electrical tests. All measurements of the ten listed
parameters in section 4.0 are within the specification limits.
The used statistics in this report are based on the tolerance limits, which are bounds to gage the
quality of the manufactured products. It assumes that if the quality of the items is normally
distributed with known mean and known standard deviation, the two-sided tolerance limits can be
calculated as follows:
+KTL = mean + (KTL) (standard deviation)
-KTL = mean - (KTL) (standard deviation)
Where +KTL is the upper tolerance limit and -KTL is the lower tolerance limit.
These tolerance limits are defined in a table of inverse normal probability distribution.
However, in most cases, mean and standard deviations are unknown and therefore it is practical
to estimate both of them from a sample. Hence the tolerance limit depends greatly on the sample
size. The Ps90%/90% KTL factor for a lot quality P of 0.9, confidence C of 0.9 with a sample size
of 5, can be found from the tabulated table (MIL-HDBK-814, page 94, table IX-B). The KTL factor
in this report is 2.742.
In the plots, the dotted lines with diamond markers are the average of the measured data points
of five samples irradiated under electrical bias while the dashed lines with X-markers are the
average of measured data points of five units irradiated with all pins tied to ground. The solid lines
with triangle markers are the 90%/90% minimum and maximum determined from the calculation
of the KTL on the samples irradiated in the biased setup. The solid lines with square symbols are
the 90%/90% minimum and maximum determined from the calculation of the KTL on the five
samples irradiated with all pins grounded. The orange solid lines with circle markers are the
specification limits.
The 11 Krads(Si) test limits are taken from the Linear Technology datasheet’s 10 Krads(Si)
specification limits. The 22 Krads(Si) test limits are taken from the Linear Technology datasheet’s
20 Krads(Si) specification limits.
