4.4.2.2 Additional criteria for device classes Q and V. The steady-state life test duration, test condition and test temperature,
or approved alternatives shall be as specified in the device manufacturer's QM plan in accordance with MIL-PRF-38535. The
test circuit shall be maintained under document revision level control by the device manufacturer's TRB in accordance with
MIL-PRF-38535 and shall be made available to the acquiring or preparing activity upon request. The test circuit shall specify the
inputs, outputs, biases, and power dissipation, as applicable, in accordance with the intent specified in method 1005 of
MIL-STD-883.
4.4.3 Group D inspection. The group D inspection end-point electrical parameters shall be as specified in table IIA herein.
4.4.4 Group E inspection. Group E inspection is required only for parts intended to be marked as radiation hardness assured
(see 3.5 herein).
a. End-point electrical parameters shall be as specified in table IIA herein.
b. For device classes Q and V, the devices or test vehicle shall be subjected to radiation hardness assured tests as
specified in MIL-PRF-38535 for the RHA level being tested. For device class M, the devices shall be subjected to
radiation hardness assured tests as specified in MIL-PRF-38535, appendix A for the RHA level being tested. All device
classes must meet the postirradiation end-point electrical parameter limits as defined in table IA at
TA = +25°C ±5°C, after exposure, to the subgroups specified in table IIA herein.
4.4.4.1 Total dose irradiation testing. Total dose irradiation testing shall be performed in accordance with MIL-STD-883,
method 1019 condition A, and as specified herein.
a. Inputs tested high, VCC = 5.5 V dc ±5%, VIN = 5.0 V dc +10%, RIN = 1 kΩ ±20%, and all outputs are open.
b. Inputs tested low, VCC = 5.5 V dc ±5%, VIN = 0.0 V dc, RIN = 1 kΩ ±20%, and all outputs are open.
4.4.4.1.1 Accelerated annealing testing. Accelerated annealing testing shall be performed on all devices requiring a RHA
level greater than 5k rads (Si). The post-anneal end-point electrical parameter limits shall be as specified in table IA herein and
shall be the pre-irradiation end-point electrical parameter limits at 25°C ±5°C. Testing shall be performed at initial qualification
and after any design or process changes which may affect the RHA response of the device.
4.4.4.2 Single event phenomena (SEP). When specified in the purchase order or contract, SEP testing shall be required on
class V devices. SEP testing shall be performed on the Standard Evaluation Circuit (SEC) or alternate SEP test vehicle as
approved by the qualifying activity at initial qualification and after any design or process changes which may affect the upset or
latchup characteristics. Test four devices with zero failures. ASTM F1192 may be used as a guideline when performing SEP
testing. The test conditions for SEP are as follows:
a. The ion beam angle of incidence shall be between normal to the die surface and 60° to the normal, inclusive
(i.e. 0° ≤ angle ≤ 60°). No shadowing of the ion beam due to fixturing or package related effects is allowed.
b. The fluence shall be ≥100 errors or ≥ 10⁷ ions/cm².
c. The flux shall be between 10² and 10⁵ ions/cm²/s. The cross-section shall be verified to be flux independent by
measuring the cross-section at two flux rates which differ by at least an order of magnitude.
d. The particle range shall be ≥ 20 micron in silicon.
e. The test temperature shall be +25°C for the upset measurements and the maximum rated operating temperature
±10°C for the latch-up measurements.
f. Bias conditions shall be defined by the manufacturer for the latch-up measurements.
g. For SEP test limits, see table IB herein.
4.5 Methods of inspection. Methods of inspection shall be specified as follows:
4.5.1 Voltage and current. Unless otherwise specified, all voltages given are referenced to the microcircuit GND terminal.
Currents given are conventional current and positive when flowing into the referenced terminal.
