Abstract:
1. A semiconductor device package comprising: a molding compound forming at least a portion of: a first package face, a second package face opposite the first package face, and package side faces extending between the first and second package faces; a semiconductor device at least partially covered by the molding compound, the semiconductor device including a plurality of I/O pads; and an electrically conductive lead frame comprising: a plurality of leads disposed proximate a perimeter of the package, each lead having a first lead surface disposed at the first package face and a bond site to which at least one of the I/O pads is electrically connected, and a die pad disposed in a central region formed by the plurality of leads, the die pad including: a first die pad surface disposed at the first package face, and a second die pad surface opposite the first die pad surface, the semiconductor device is attached to a central region of the second die pad surface, and the second die pad surface extends outward from the die and is in contact with the molding compound, at least a portion of the second die pad surface in contact with the molding compound is roughened to improve adhesion between the molding compound and the die pad, said roughened portion having an average roughness greater than 0.4 micron.
