Autoclave Testing of Plastic Encapsulated 4001 CMOS Integrated Circuits.
Abstract
Samples from 10 vendors of CMOS 4001 plastic encapsulated integrated circuits were tested in an autoclave at 121 C, 100% RH and 15 psig with and without electrical bias. Twenty-nine test groups of 16 circuits each accumulated over 200,000 device hours. Failure analyses were performed to verify moisture related electrochemical aluminum metal corrosion on the die. Weibull failure distributions showed large differences in moisture resistance reliability among the various vendor products. Test devices with newer data coded packages had longer median life times. There was no correlation of median life time between groups with and without electrical bias. (Author)
