Semiconductor device package with integral thermal dissipation structure

Abstract

An example includes: a package substrate having a die pad with a device side surface and a thermal pad on an opposite side surface; a thermal dissipation structure mounted to the die pad, the thermal dissipation structure including a thermally conductive insulator core and thermal conductors on a device side surface and on a substrate mount surface opposite the device side surface; at least one semiconductor device die mounted to the device side surface of the thermal dissipation structure; electrical connections formed between leads on the package substrate and bond pads on the at least one semiconductor device die; and mold compound covering the electrical connections, the at least one semiconductor device, and portions of the package substrate, portions of the leads of the package substrate forming terminals, and the thermal pad exposed from the mold compound and forming a thermal pad for a semiconductor device package.
