Abstract
A high-power semiconductor device module is implemented with a cavity in the molding package. The cavity reduces a volume of the molding compound, preventing an accumulation of stress in the module, and associated warpage of the package. Chip assemblies within the module are designed to fit within the cavity, so that semiconductor dies, and sensing devices therein are protected from damage during a sintering process in which the module is mounted to a heat sink. After the sintering process, the cavity can be sealed with a gel material. The molding package described herein can also enhance reliability of the module during operation, ensuring that the product is robust for electric and hybrid electric vehicle applications.
