Electromigration is one of failure mechanisms of semiconductor, but the failure mode can appear as a short, open, or characteristic degradation. Capacitors have several failure modes, the degree of which depends on the type of capacitor (Table 1).
Mechanisms and failure modes according to the stress in an electrolytic capacitor. A normal use of the capacitor leads to the evaporation of the electrolyte and the repair of the oxide layer. These are two causes of electrolyte disappearance, which is the main cause of capacitor degradation under normal conditions.
However, excessive electrical, mechanical, or operating environment stresses or design flaws during the manufacture or use of electronic equipment cloud give rise to capacitor failure, smoke, ignition, or other problems. This paper describes failure modes and failure mechanisms with a focus on Al-Ecap, MF-cap, and MLCC used in power electronics.
There are many studies on the failure modes of electrolytic capacitors, and mainly aluminum electrolytic capacitors. Indeed, from the understanding of the mechanisms and failure modes of a capacitor, it is possible to apply a maintenance in order to know the remaining lifetime of the component.
As with any other capacitors, t environmental and electrical factors have a significant impact on the failure and life of MF-cap, though. The most important reliability feature of MF-cap is their self-healing capability and the self-healing determines the mode of failure.
The failure mode of thin film capacitors may be short circuit or open circuit, depending on the dominant failure mechanism. There are only a certain number of electrical breakdown events which can occur within a capacitor before there is a risk of the self-healing process no longer being effective and a short circuit failure mode occurring.
