A Review of Power Cycle Driven Fatigue, Aging, and Failure Modes for Semiconductor Power Modules

摘要

Semiconductor power modules are widely used in the electric power conversion applications. The reliability of semiconductor power modules is one of the critical concerns for power converter design, operation, and lifetime estimation. This paper reviews the power cycle driven fatiguing causes, aging process, the failure modes of semiconductor power modules. Function components in a semiconductor power module including semiconductor dies, bond wires, solder layers, and insulated silicone gel are discussed regarding the aforementioned issues.
