1.0. Overview and Background
It is well known that total dose ionizing radiation can cause parametric degradation and ultimately
functional failure in electronic devices. The damage occurs via electron-hole pair production, transport
and trapping in the dielectric regions. In advanced CMOS technology nodes (0.6μm and smaller) the
bulk of the damage is manifested in the thicker isolation regions, such as shallow trench or local
oxidation of silicon (LOCOS) oxides (also known as “birds-beak” oxides). However, many linear and
mixed signal devices that utilize bipolar minority carrier elements exhibit an enhanced low dose rate
sensitivity (ELDRS). At this time there is no known or accepted a priori method for predicting
susceptibility to ELDRS or simulating the low dose rate sensitivity with a “conventional” room
temperature 50-300rad(Si)/s irradiation (Condition A in MIL-STD-883G TM 1019.7). Over the past 10
years a number of accelerating techniques have been examined, including an elevated temperature
anneal, such as that used for MOS devices (see ASTM-F-1892 for more technical details) and irradiating
at various temperatures. However, none of these techniques have proven useful across the wide variety
of linear and/or mixed signal devices used in spaceborne applications.
The latest requirement incorporated in MIL-STD-883G TM 1019.7 requires that devices that could
potentially exhibit ELDRS “shall be tested either at the intended application dose rate, at a prescribed
low dose rate to an overtest radiation level, or with an accelerated test such as an elevated temperature
irradiation test that includes a parameter delta design margin”. While the recently released MIL-STD883 TM 1019.7 allows for accelerated testing, the requirements for this are to essentially perform a low
dose rate ELDRS test to verify the suitability of the acceleration method on the component of interest
before the acceleration technique can be instituted. Based on the limitations of accelerated testing and to
meet the requirements of MIL-STD-883G TM 1019.7 Condition D, we have performed an ELDRS test
at 10mrad(Si)/s.
2.0. Radiation Test Apparatus
The ELDRS testing described in this final report was performed using the facilities at Radiation Assured
Devices’ Longmire Laboratories in Colorado Springs, CO. The ELDRS source is a GB-150 irradiator
modified to provide a panoramic exposure. The Co-60 rods are held in the base of the irradiator heavily
shielded by lead. During the irradiation exposures the rod is raised by an electronic timer/controller and
the exposure is performed in air. The dose rate for this irradiator in this configuration ranges from
approximately 1mrad(Si)/s to a maximum of approximately 50rad(Si)/s as determined by the distance
from the source. For the low dose rate ELDRS testing described in this report, the devices are placed
approximately 2-meters from the Co-60 rods. The irradiator calibration is maintained by Radiation
Assured Devices’ Longmire Laboratories using thermoluminescent dosimeters (TLDs) traceable to the
National Institute of Standards and Technology (NIST). Figure 2.1 shows a photograph of the Co-60
irradiator at RAD’s Longmire Laboratory facility.

3.0. Radiation Test Conditions
The RH117H-Positive Adjustable Regulator described in this final report was irradiated under 2
different conditions, one when biased with a split +/-15V supply, and one when unbiased with all pins
tied to ground. See Appendix B for details on the biasing conditions during radiation exposure. In our
opinion, these bias circuits satisfy the requirements of MIL-STD-883G TM1019.7 Section 3.9.3 Bias
and Loading Conditions which states “The bias applied to the test devices shall be selected to produce
the greatest radiation induced damage or the worst-case damage for the intended application, if known.
While maximum voltage is often worst case some bipolar linear device parameters (e.g. input bias
current or maximum output load current) exhibit more degradation with 0 V bias.”
The devices were irradiated to a maximum total ionizing dose level of 50krad(Si) with incremental
readings at 10, 20, 30 and 50krad(Si). Electrical testing occurred within one hour following the end of
each irradiation segment. For intermediate irradiations, the units were tested and returned to total dose
exposure within two hours from the end of the previous radiation increment. The TID bias board was
positioned in the Co-60 cell to provide the required maximum dose rate of 10mrad(Si)/s and was located
inside a lead-aluminum enclosure. The lead-aluminum enclosure is required under MIL-STD-883G
TM1019.7 Section 3.4 that reads as follows: “Lead/Aluminum (Pb/Al) container. Test specimens shall
be enclosed in a Pb/Al container to minimize dose enhancement effects caused by low-energy, scattered
radiation. A minimum of 1.5 mm Pb, surrounding an inner shield of at least 0.7 mm Al, is required.
This Pb/Al container produces an approximate charged particle equilibrium for Si and for TLDs such as
CaF2. The radiation field intensity shall be measured inside the Pb/Al container (1) initially, (2) when
the source is changed, or (3) when the orientation or configuration of the source, container, or testfixture is changed. This measurement shall be performed by placing a dosimeter (e.g., a TLD) in the
device-irradiation container at the approximate test-device position. If it can be demonstrated that low
energy scattered radiation is small enough that it will not cause dosimetry errors due to dose
enhancement, the Pb/Al container may be omitted”.
The final dose rate within the lead-aluminum box was determined based on TLD dosimetry
measurements just prior to the beginning of the total dose irradiations. The final dose rate for this work
was 10mrad(Si)/s with a precision of ±5%.

Appendix C details the measured parameters, test conditions, pre-irradiation specification and

The parametric data was obtained as “read and record” and all the raw data plus an attributes summary
are contained in this report as well as in a separate Excel file. The attributes data contains the average,
standard deviation and the average with the KTL values applied. The KTL values used is 2.742 per
MIL HDBK 814 using one sided tolerance limits of 90/90 and a 5-piece sample size. This survival
probability/level of confidence is consistent with a 22-piece sample size and zero failures analyzed using
a lot tolerance percent defective (LTPD) approach. Note that the following criteria must be met for a
device to pass the low dose rate test: following the radiation exposure each of the 5 pieces irradiated
under electrical bias shall pass the specification value. The units irradiated without electrical bias and
the KTL statistics are included in this report for reference only. If any of the 5 pieces irradiated under
electrical bias exceed the datasheet specifications, then the lot could be logged as a failure.
Further, MIL-STD-883G, TM 1019.7 Section 3.13.1.1 Characterization test to determine if a part
exhibits ELDRS” states the following: Select a minimum random sample of 21 devices from a
population representative of recent production runs. Smaller sample sizes may be used if agreed upon
between the parties to the test. All of the selected devices shall have undergone appropriate elevated
temperature reliability screens, e.g. burn-in and high temperature storage life. Divide the samples into
four groups of 5 each and use the remaining part for a control. Perform pre-irradiation electrical
characterization on all parts assuring that they meet the Group A electrical tests. Irradiate 5 samples
under a 0 volt bias and another 5 under the irradiation bias given in the acquisition specification at 50300 rad(Si)/s and room temperature. Irradiate 5 samples under a 0 volt bias and another 5 under
irradiation bias given in the acquisition specification at < 10mrad(Si)/s and room temperature. Irradiate
all samples to the same dose levels, including 0.5 and 1.0 times the anticipated specification dose, and
repeat the electrical characterization on each part at each dose level. Post irradiation electrical
measurements shall be performed per paragraph 3.10 where the low dose rate test is considered
Condition D. Calculate the radiation induced change in each electrical parameter (Δpara) for each
sample at each radiation level. Calculate the ratio of the median Δpara at low dose rate to the median
Δpara at high dose rate for each irradiation bias group at each total dose level. If this ratio exceeds 1.5

for any of the most sensitive parameters then the part is considered to be ELDRS susceptible. This test
does not apply to parameters which exhibit changes that are within experimental error or whose values
are below the pre-irradiation electrical specification limits at low dose rate at the specification dose.
Therefore, the data in this report can be analyzed along with the high dose rate report titled “Total
Ionizing Dose (TID) Testing of the RH117H-Positive Adjustable Regulator for Linear Technology” to
demonstrate that these parts do not exhibit ELDRS as defined in the current test method.
5.0. ELDRS Test Results
Using the conditions stated above, the RH117H-Positive Adjustable Regulator (from the lot date code
identified on the first page of this test report) passed the enhanced low dose rate sensitivity test to
50krad(Si) with all parameters remaining within their pre- and/or post-radiation specification limits. As
noted above (Section 4) the data for the units-under-test irradiated in the unbiased condition and the
KTL statistics presented in this report are for reference only and are not used for the determination of
“PASS/FAIL” for the lot.
Figures 5.1 through 5.15 show plots of all the measured parameters versus total ionizing dose while
Tables 5.1 – 5.15 show the corresponding raw data for each of these parameters. In these data plots the
solid diamonds are the average of the measured data points for the sample irradiated under electrical bias
while the shaded diamonds are the average of the measured data points for the units irradiated with all
pins tied to ground. The black lines (solid or dashed) are the average of the data points after application
of the KTL statistics on the sample irradiated in the biased condition while the shaded lines (solid or
dashed) are the average of the data points after application of the KTL statistics on the sample irradiated
in the unbiased condition. The red dotted line(s) are the pre- and/or post-irradiation minimum and/or
maximum specification value as defined in the datasheet and/or test plan.
In addition to the radiation test results, the data plots and tables described above contain anneal data.
The anneals are performed to better understand the underlying physical mechanisms responsible for
radiation-induced parametric shifts and are not part of the criteria used to establish whether or not the lot
passes or fails the low dose rate test. In all cases the parts either improved or exhibited no change
during the anneal.
As seen clearly in these figures, the pre- and post-irradiation data are well within the specification even
after application of the KTL statistics and the control units, as expected, show no significant changes to
any of the parameters throughout the course of the measurements. Therefore we can conclude that the
observed degradation was due to the radiation exposure and not drift in the test equipment.

Figure 5.6. Plot of Load Regulation VOUT<=5V (mV) versus total dose. The solid diamonds are the average
of the measured data points for the samples irradiated under electrical bias while the shaded diamonds are the
average of the measured data points for the samples irradiated with all pins tied to ground. The black lines
(solid and/or dashed) are the average of the data points after application of the KTL statistics on the samples
irradiated under electrical bias while the gray lines (solid and/or dashed) are the average of the data points after
application of the KTL statistics on the samples irradiated in the unbiased condition. The red dotted line(s) are
the pre- and/or post-irradiation minimum and/or maximum specification value as defined in the datasheet
and/or test plan.

the average of the measured data points for the samples irradiated under electrical bias while the shaded
diamonds are the average of the measured data points for the samples irradiated with all pins tied to ground.
The black lines (solid and/or dashed) are the average of the data points after application of the KTL statistics
on the samples irradiated under electrical bias while the gray lines (solid and/or dashed) are the average of the
data points after application of the KTL statistics on the samples irradiated in the unbiased condition. The red
dotted line(s) are the pre- and/or post-irradiation minimum and/or maximum specification value as defined in
the datasheet and/or test plan.

measured data points for the samples irradiated under electrical bias while the shaded diamonds are the
average of the measured data points for the samples irradiated with all pins tied to ground. The black lines
(solid and/or dashed) are the average of the data points after application of the KTL statistics on the samples
irradiated under electrical bias while the gray lines (solid and/or dashed) are the average of the data points after
application of the KTL statistics on the samples irradiated in the unbiased condition. The red dotted line(s) are
the pre- and/or post-irradiation minimum and/or maximum specification value as defined in the datasheet
and/or test plan.

6.0. Summary / Conclusions
The ELDRS testing described in this final report was performed using the facilities at Radiation Assured
Devices’ Longmire Laboratories in Colorado Springs, CO. The ELDRS source is a GB-150 irradiator
modified to provide a panoramic exposure. The Co-60 rods are held in the base of the irradiator heavily
shielded by lead. During the irradiation exposures the rod is raised by an electronic timer/controller and
the exposure is performed in air. The dose rate for this irradiator in this configuration ranges from
approximately 1mrad(Si)/s to a maximum of approximately 50rad(Si)/s as determined by the distance
from the source.
Samples of the RH117H-Positive Adjustable Regulator described in this report were irradiated biased
with a split ±15V supply and unbiased (all leads tied to ground). The devices were irradiated to a
maximum total ionizing dose level of 50krad(Si) with a pre-rad baseline reading as well as incremental
readings at 10, 20, and 30krad(Si). Electrical testing occurred within one hour following the end of each
irradiation segment. For intermediate irradiations, the units were tested and returned to total dose
exposure within two hours from the end of the previous radiation increment. In addition, all unitsunder-test received a 24hr room temperature and 168hr 100°C anneal, using the same bias conditions as
the radiation exposure.
The parametric data was obtained as read and record and all the raw data plus an attributes summary are
contained in a separate Excel file. The attributes data contains the average, standard deviation and the
average with the KTL values applied. The KTL value used in this work is 2.742 per MIL-HDBK-814
using one sided tolerance limits of 90/90 and a 5-piece sample size. The 90/90 KTL values were
selected to match the statistical levels specified in the MIL-PRF-38535 sampling plan for the
qualification of a radiation hardness assured (RHA) component. Note that the following criteria must be
met for a device to pass the low dose rate test: following the radiation exposure each of the 5 pieces
irradiated under electrical bias shall pass the specification value. The units irradiated without electrical
bias and the KTL statistics are included in this report for reference only. If any of the 5 pieces irradiated
under electrical bias exceed the datasheet specifications, then the lot could be logged as a failure.
Using the conditions stated above, the RH117H-Positive Adjustable Regulator (from the lot date code
identified on the first page of this test report) passed the enhanced low dose rate sensitivity test to
50krad(Si) with all parameters remaining within their pre- and/or post-radiation specification limits.
Note that the data for the units-under-test irradiated in the unbiased condition and the KTL statistics
presented in this report are for reference only and are not used for the determination of “PASS/FAIL”
for the lot. Further, the data in this report can be analyzed along with the low dose rate report titled
“Total Ionizing Dose (TID) Testing of the RH117H-Positive Adjustable Regulator for Linear
Technology” to demonstrate that these parts do not exhibit ELDRS as defined in the current test method.

Appendix C: Electrical Test Parameters and Conditions
All electrical tests for this device are performed on one of Radiation Assured Device’s LTS2020 Test
Systems. The LTS2020 Test System is a programmable parametric tester that provides parameter
measurements for a variety of digital, analog and mixed signal products including voltage regulators,
voltage comparators, D to A and A to D converters. The LTS2020 Test System achieves accuracy and
sensitivity through the use of software self-calibration and an internal relay matrix with separate family
boards and custom personality adapter boards. The tester uses this relay matrix to connect the required
test circuits, select the appropriate voltage / current sources and establish the needed measurement loops
for all the tests performed. The tests will be conducted using the LTS-2101 Linear Family Board, LTS0606 Socket Assembly and the RH117 DUT board. The measured parameters and test conditions are
shown in Tables C.1.
A listing of the measurement precision/resolution for each parameter is shown in Tables C.2. The
precision/resolution values were obtained either from test data or from the DAC resolution of the LTS2020. To generate the precision/resolution shown in Table C.2, one of the units-under-test was tested
repetitively (a total of 10-times with re-insertion between tests) to obtain the average test value and
standard deviation. Using this test data MIL-HDBK-814 90/90 KTL statistics were applied to the
measured standard deviation to generate the final measurement range. This value encompasses the
precision/resolution of all aspects of the test system, including the LTS2020 mainframe, family board,
socket assembly and DUT board as well as insertion error. In some cases, the measurement resolution is
limited by the internal DACs, which results in a measured standard deviation of zero. In these instances
the precision/resolution will be reported back as the LSB of the DAC.
Note that the testing and statistics used in this document are based on an “analysis of variables”
technique, which relies on small sample sizes to qualify much larger lot sizes (see MIL-HDBK-814, p.
91 for a discussion of statistical treatments). Not all measured parameters are well suited to this
approach due to inherent large variations. If necessary, larger samples sizes could be used to qualify
these parameters using an “attributes” approach.
