Abstract :
This paper presents an overview of the main causes of failures of
modern power semiconductor switching devices such as power MOSFETs,
IGBTs and GTOs. Attention is paid especially to problems of both the
homogeneity of semiconductor structures and operating conditions.
One of the most frequent causes of device failure is
electrothermally induced stress (especially in the case of power
module encapsulations), which can result in thermal fatigue faults
in sequential operation mode applications. A comparison of empirical
formulae with experimental results has been carried out and
considerations concerning conditioning reliability of power
semiconductor devices have been formulated. Some modern trends in
controlling devices and the possible use of new semiconductor
materials for device fabrication from viewpoints of reliability are
also discussed.
