Abstract :
Removal of silicon by CF4/O2plasma etching combined with optical microscope and SEM examinations of the exposed aluminum surface have been used to determine that the cause of life test failure in aluminum/silicon-alloy diodes was the presence of traces of alkali metal in the aluminum pellets used.
