SUMMARY ALL FIVE PARTS PASSED THE ELECTRICAL TEST LIMITS AS SPECIFIED IN THE DATASHEET AFTER IRRADIATION TO 1E12 N/cm2. ADDITIONAL INFORMATION CAN BE PROVIDED PER REQUEST. P a g e 2 | 36 LINEAR TECHNOLOGY CORPORATION DDD RH1028MW W1117814.1 W2 1.0 Overview and Background Neutron particles incident on semiconductor materials lose energy along their paths. The energy loss produces electron-hole pairs (ionization) and displaces atoms in the material lattice (displacement damage defects or DDD). DDD induces a mixture of isolated and clustered defects or broken bonds. Such defects elevate the energy level of the material and consequently change material and electrical properties. The altering energy level creates the combination of any of the following processes, thermal generation of electron-hole pairs, recombination, trapping, compensation, tunneling, affecting hence the devices’ basic features. Bipolar technology is susceptible to neutron displacement damage around a fluence level of 1E12 neutron/cm2. The neutron radiation test for the RH1028MW determines the change in device performance as a function of neutrons’ fluence. 2.0 Radiation Facility: Five samples were irradiated unbiased at the University of Massachusetts, Lowell, using the Reactor Facility-FNI. The neutron flux was determined by system S/P-32, method ASTM E-265, to be 4.05E9 N/cm2-s (1MeV equivalent) for each irradiation step. Refer to Appendix C for the certificate of dosimetry. 3.0 Test Conditions Five samples and two control units were electrically tested at 25°C prior to irradiation. The testing was performed on the two control units to confirm the operation of the test system prior to the electrical testing of the 7 units (5 irradiated and 2 control). During irradiation, devices were placed into an anti-static bag. Devices were then vertically aligned with the radiation source. The criteria to pass the neutron displacement damage test is that five irradiated samples 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 in accordance with method 5004, MIL-STD-883, and if valid the lot will be scrapped. P a g e 3 | 36 LINEAR TECHNOLOGY CORPORATION DDD RH1028MW W1117814.1 W2 4.0 Tested Parameters The following parameters were measured pre- and post-irradiations at VS = +/- 15V, VCM = 0V unless otherwise noted: - Input Offset Voltage VOS (uV) Input Offset Current IOS (nA) Positive Bias Current + IB (nA) Negative Bias Current – IB (nA) Positive Slew Rate +SR (V/uS) Negative Slew Rate –SR (V/uS) Common Mode Rejection Ratio CMRR (dB) Power Supply Rejection Ratio PSRR (dB) Large-Signal Voltage Gain AVOL (V/uV) Positive Output Voltage Swing (V) at RL = 2KΩ Negative Output Voltage Swing (V) at RL = 2KΩ Positive Output Voltage Swing (V) at RL = 600Ω Negative Output Voltage Swing (V) at RL = 600Ω Appendix D details the test conditions, minimum and maximum values at different accumulated doses. P a g e 4 | 36 LINEAR TECHNOLOGY CORPORATION DDD RH1028MW W1117814.1 W2 5.0 Test Results All five samples passed the post-irradiation electrical tests. All measurements of the thirteen 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 dashed lines with X-markers are the measured data points of five postirradiated samples. The solid lines with square symbols are the computed KTL values of five post-irradiated samples with the application of the KTL statistics. The orange solid lines with circle markers are the datasheet specification limits. The post-irradiation test limits are using Linear Technology datasheets 100 Krads(Si) specification limits.
