Abstract
A semiconductor package includes a lead frame having a die paddle and a plurality of leads connected to die paddle, where each lead has a lead surface parallel to die paddle and is a continuous extension bending upward from die paddle. A semiconductor chip is mounted on die paddle, where drain metal layer covering a first surface of chip is connected to die paddle, and source metal layer and gate metal layer are located on a second surface opposite to first surface with gate metal layer located at one corner of the second surface. A source metal plate and a gate metal plate are attached on source metal layer and gate metal layer respectively. A molding layer covers lead frame, semiconductor chip, source metal plate and gate metal plate, where lead surface, top surfaces of source metal plate and gate metal plate are exposed from top surface of molding layer.
