Abstract : Transistors which have become inoperative due to collector-emitter short circuits have usually been driven into second breakdown itself, however, is not the destructive mechanism. Alloying of the contact metalization into the device produces the short circuit which is observed. This report describes the experimental results of transistors having molybdenum-aluminum metalization compared to devices with only aluminum contacts. The results indicated that devices with molybdenum, when driven into second breakdown, would outlive aluminum units with respect to current by a factor of three. (Author)
