Failure Characteristics and Mechanism Analysis of IGBT Modules under High-Temperature Power Cycling
Failure types and mechanism of IGBT modules according to the module structure and different operation stages are analyzed
and three types of package failure mechanism affecting the lifetime of IGBT are discussed. The package failure types and modes are concerned with the lift-off and meltdown of bonded-wires
solder fatigue
and reconstruction of metallization. The failures of bonded-wires are generally caused by a great change in junction temperature and high temperature gradient. The detection and inspection of the failure process of bonded-wires
the structure of chip surface
and the delamination and cracks and voids in solder layers by means of the instruments demonstrate that the main failure mode of high junction temperature and temper
ature gradient is the lift-off and meltdown of bonded-wires. The overload of one or more bonded-wires leads to an unbalanced distribution of the current. When V
CE
gradually becomes big
then a sharp jump happens before failure
the junction-case thermal resistance remains steady
and the value of IGBT lifetime is approximate to that of Weibull distribution. By investigating various microscopes and infrared thermal imaging
the failure characteristics are obtained. Failure characteristic distribution show that after power cycle
the central area of the chip surface
insulating protective ring of the original cell structure become no longer symmetry with small black circles
holes
and cracks. The defects of the contact physical layer decrease downwardly. From baseplate to chip surface
IGBT module flatness of the physical layer exhibits a decreasing trend. The sharp jump position of V
CE
can be considered as the IGBT reliability evaluation standard.
