Abstract
An abnormal base current behavior with an ideality of about 3 is often observed in the AlGaAs/GaAs HBT after it is subjected to a high tempe rature/electrical burn-in condition. Using a two-dimensional device si mulator, this paper studies and determines the main physical mechanism s contributing to such an abnormality. Data measured from two post-bur n-in HBTs are included in support of the finding. (C) 1998 Published b y Elsevier Science Ltd.
