This is achieved by selecting representative devices within a process, package or business unit and performing a series of reliability tests to ensure that the reliability has maintained over time. Listed below are the overall results for the last quarter. 1. High Temperature Operating Life (125° - 150°C; 0 failures) Failure Rate: 4 FITS (1,560K device-hours) Note: The Exponential Model is used to derive FIT rates (60% Confidence; EA = 0.6 eV). Also, Thermal and Voltage Acceleration are used to compute the overall acceleration factor. Weighted acceleration factors (WAF) for a group of products are calculated by taking the weighted average of each device’s acceleration factor multiplied by its corresponding device hours. All failures were inconclusive. 2. Data Retention Bake (150°C; 0 failures) Failure Rate: 16 FITS (481K device-hours) Note: The Exponential Model is used to derive FIT rates (60% Confidence; EA = 0.6 eV). Since there is no bias applied during testing and the stress temperature is fixed for all devices at 150°C, the acceleration factor is 117 for all groupings. 3. Temperature Cycle (-65°C to 150°C, 500 cycles) * Failure Rate: 0.00% (0 failures out of 310 units) 4. Temperature Humidity Bias (85°C/85%RH) and HAST (130°C/85%RH) * Failure Rate: 0.00% (0 failures out of 4,741K device-hours) Note: A 20:1 Acceleration Factor is used to combine HAST results with THB). 5. Steam Pressure Pot (121°C/100%RH) * Failure Rate: 0.00% (0 failures out of 311 units) RELIABILITY MONITOR -- ATMEL PROPRIETARY * indicates that preconditioning is performed prior to the stress test. 1 High Temperature Operating Life (sorted by FAMILY) BU QTR 48 Hours 168 Hours 500 Hours 1K Hours REJ SS REJ SS REJ SS REJ SS Device-Hours* WAF EFR PPM FITS APG 4 LAST 4Q 0 0 82 328 0 0 82 328 0 0 82 328 0 0 82 328 82,000 328,000 23 23 0 0 492 123 ASIC 4 LAST 4Q 0 0 220 1,110 0 0 220 910 0 0 220 910 0 0 200 800 210,000 864,600 22 26 0 0 200 41 MEMORY 4 LAST 4Q 0 0 492 1,572 0 0 300 1,200 0 0 300 1,200 0 0 299 1,199 308,716 1,217,356 46 47 0 0 64 16 MCU 4 LAST 4Q 0 0 3,196 69,778 0 0 416 1,132 0 0 237 953 0 0 0 331 282,012 3,967,080 19 6 0 0 169 39 RFA 4 LAST 4Q 0 0 1,973 4,437 0 0 693 3,157 0 0 693 3,157 0 0 539 1,771 677,440 2,448,440 266 159 0 0 5 2 ATMEL 4 LAST 4Q 0 0 5,963 77,225 0 0 1,711 6,727 0 0 1,532 6,548 0 0 1,120 4,429 1,560,168 8,825,476 132 57 0 0 4 2 RELIABILITY MONITOR -- ATMEL PROPRIETARY 2 High Temperature Operating Life (sorted by TECHNOLOGY) TECH QTR 48 Hours 168 Hours 500 Hours 1K Hours REJ SS REJ SS REJ SS REJ SS Device-Hours* WAF EFR PPM FITS UHF 4 LAST 4Q 0 0 77 231 0 0 77 231 0 0 77 231 0 0 77 77 77,000 154,000 52 84 0 0 102 70 SCMOS3 4 LAST 4Q 0 122 0 122 0 122 0 0 61,000 75 0 200 4 LAST 4Q 0 231 0 231 0 231 0 0 115,500 67 0 119 4 LAST 4Q 0 77 0 77 0 77 0 77 77,000 206 0 58 4 LAST 4Q 0 231 0 231 0 231 0 231 231,000 142 0 28 75K 4 LAST 4Q 0 0 1,434 1,973 0 0 154 693 0 0 154 693 0 0 154 539 215,440 677,440 667 290 0 0 6 5 58K 4 LAST 4Q 0 0 408 2,854 0 0 179 532 0 0 0 353 0 0 0 77 41,064 356,528 3 8 0 0 7,457 331 57K 4 LAST 4Q 0 0 100 400 0 0 100 400 0 0 100 400 0 0 100 400 100,000 400,000 23 23 0 0 403 101 56K 4 LAST 4Q 0 0 120 397 0 0 120 397 0 0 120 397 0 0 100 377 110,000 387,000 21 21 0 0 398 113 46K 4 LAST 4Q 0 0 82 246 0 0 82 246 0 0 82 246 0 0 82 246 82,000 246,000 23 23 0 0 492 164 45.6K 4 LAST 4Q 0 313 0 313 0 313 0 236 274,500 106 0 31 4 LAST 4Q 0 231 0 231 0 231 0 231 231,000 142 0 28 4 LAST 4Q 0 231 0 231 0 231 0 0 38,500 142 0 168 40K 4 LAST 4Q 0 0 77 154 0 0 77 154 0 0 77 154 0 0 77 154 77,000 154,000 117 117 0 0 102 51 38.6 K 4 LAST 4Q 0 0 154 154 0 0 154 154 0 0 154 154 0 0 154 154 154,000 154,000 117 117 0 0 51 51 35K 4 LAST 4Q 0 0 3,219 68,508 0 0 668 2,184 0 0 668 2,184 0 0 277 1,331 594,948 4,941,052 35 18 0 0 45 10 SAC2NV BCDMOS 40009 45201 45102 RELIABILITY MONITOR -- ATMEL PROPRIETARY 3 High Temperature Operating Life (sorted by TECHNOLOGY) TECH QTR 48 Hours 168 Hours 500 Hours 1K Hours REJ SS REJ SS REJ SS REJ SS Device-Hours* WAF EFR PPM FITS 34K 4 LAST 4Q 0 0 292 292 0 0 100 100 0 0 100 100 0 0 99 99 108,716 108,716 42 42 0 0 202 202 19K 4 LAST 4Q 0 580 0 200 0 200 0 200 218,240 42 0 101 4 LAST 4Q 0 0 5,963 77,225 0 0 1,711 6,727 0 0 1,532 6,548 0 0 1,120 4,429 1,560,168 8,825,476 132 57 0 0 4 2 ATMEL * The Device-Hours computation includes additional read-outs not detailed in the report.

Stressing at high temperatures (150°C for plastic packages) accelerates any discharge causing the memory state to change. Failures In Time (FITS): This is the unit measure for expressing failure rates and is identical to the expression PPM/K hours. For example, three failures out of a million components tested for one thousand hours equates to 3 FITS. High Temperature Operating Life (HTOL): The purpose of this test is to accelerate thermally activated failure mechanisms through the use of high temperatures (typically between 125°C and 150°C), increased voltage, and dynamic bias conditions. Readouts at various time points are taken to determine the Early Failure Rate (EFR) and Intrinsic Failure Rate (IFR). EFR is expressed in defective parts per million (DPPM) and IFR is expressed in Failures in Time (FITS at 55°C). Highly Accelerated Stress Test (HAST): The purpose of this test is to evaluate a plastic packaged component’s ability to withstand harsh environmental conditions with extreme temperature and humidity levels. The parts are stressed to high temperature (130°C) and relative humidity (85%RH) conditions in a biased state to achieve maximum acceleration. Steam Pressure Pot (SPP): The test is used to evaluate a plastic packaged component’s ability to withstand severe conditions of pressure (15 psig), temperature (121°C), and humidity (100%RH). Temperature Cycle (TC): This test is used to measure a product’s sensitivity to thermal stresses due to differences in expansion and contraction characteristics of the die and mold compound by repeated alternating temperature dwells between high and low temperature extremes. Temperature Humidity Bias (THB): The purpose of this test (85°C/85%RH) is identical to HAST. The only difference is that HAST accelerates THB by a factor of 20:1 due to the increase in temperature during test. RELIABILITY MONITOR -- ATMEL PROPRIETARY 12
