RELIABILITY MONITOR -- ATMEL PROPRIETARY
Reliability Monitor Report
Date:
Nov 19, 2009
Executive Summary
The intent of the Reliability Monitor Program is to measure the reliability of previously
qualified devices on a quarterly basis. 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: 8 FITS (1,954K 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: 15 FITS (534K 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 461 units)
4.
Temperature Humidity Bias (85°C/85%RH) and HAST (130°C/85%RH) *
Failure Rate: 0.00% (0 failures out of 762K 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 461 units)
RELIABILITY MONITOR -- ATMEL PROPRIETARY
* indicates that preconditioning is performed prior to the stress test.

Definitions
Data Retention Bake (DRB): This test is used to measure a device’s ability to
retain a charge for extended periods of time without applying voltage bias.
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.
