    摘要: A molded semiconductor package includes a substrate having opposing first and second main surfaces, a semiconductor die attached to the first main surface of the substrate, an adhesion adapter attached to the second main surface of the substrate or a surface of the semiconductor die facing away from the substrate, and a mold compound encapsulating the semiconductor die, the adhesion adapter and at least part of the substrate. The adhesion adapter is configured to adapt adhesion properties of the mold compound to adhesion properties of the substrate or semiconductor die to which the adhesion adapter is attached, such that the mold compound more strongly adheres to the adhesion adapter than directly to the substrate or semiconductor die to which the adhesion adapter is attached. The adhesion adapter has a surface feature which strengthens the adhesion between the adhesion adapter and the mold compound.

    摘要: A lead frame strip having a plurality of unit lead frames is provided. Each of the unit lead frames have a die paddle and a plurality of leads extending away from the die paddle. A first one of the unit lead frames is plated with an adhesion promoter plating material within a package outline area of the first unit lead frame. The package outline area includes one of the die paddles and interior portions of the leads. Wire bond sites are processed in the first unit lead frame before or after the plating of the first lead frame such that, after the plating of the first lead frame. The wire bond sites are substantially devoid of the adhesion promoter plating material. The wire bond sites are disposed within the package outline area at an end of the interior portions of the leads that is closest to the die paddle.
