Abstract:
A semiconductor package formed utilizing a removable backside protective layer includes a leadframe, a die pad, leads and a molding compound around them. The first surface of the die pad and leads are exposed to an external environment by the plurality of recesses. The recesses are formed by coupling a removable backside protective layer to the leadframe before applying the molding compound. After the molding compound is applied and cured, the backside protective layer is removed to expose the first surface of the die pad and the first surfaces of the leads so the semiconductor package may be mounted within an electronic device. The removable backside protective layer protects the die pad and the leads from mold flashing and residue when forming the semiconductor package during the fabrication process.
