The invention claimed is a packaged semiconductor device with dual exposed surfaces and a method of manufacturing the device. A thermal clip and one or multiple source pads are exposed on opposite ends of the device through a nonconductive molding material used to package the device. The thermal clip and source pad can be either top or bottom-exposed. The gate, source and drain leads are exposed through the molding material, and all leads are coplanar with the bottom-exposed surface. The device can have multiple semiconductor dies or various sized dies while still having a single, constant footprint. The method of manufacturing requires attaching the semiconductor die to a thermal clip, and then attaching the die with the attached thermal clip to a lead frame. The resulting device is then molded, marked, trimmed and singulated, in this order, creating a packaged semiconductor device with dual exposed surfaces.
