Abstract
Disclosed examples include power modules and fabrication methods therefor in which one or more power device dies include a switching device and a second device die with a circuit component are mounted to a lead frame or other interconnect structure on a substrate structure, and a body structure is formed around portions of the power module providing a first opening to expose a portion of the substrate structure to provide an externally accessible first exposed surface along the top of the power module, and the body structure includes a second opening exposing a portion of the first device die along the bottom of the power module to provide a thermally conductive path to draw heat away from the power device dies.
