Semiconductor device with integral EMI shield
A shielded semiconductor device has a first die attached to a die pad of a lead frame and a second die attached to a surface of the first die. The first die is electrically connected to inner lead ends of leads that surround the die pad, and the second die is electrically connected to the first die and to an inner end of a shielding lead. A mold compound forms a body around the first and second dies and the electrical connections. Outer lead ends of the leads project from the sides of the body. The outer end of the shielding lead projects from a central location of one side of the body and is bent up the side surface from which it projects and over the top of the body and provides EMI shielding.

Reduced-length bond pads for broadband power amplifiers
In a transistor formed on a semiconductor die mounted on a substrate, where the transistor output is connected to a circuit on the substrate, a bond pad electrically connected to a transistor drain finger manifold extends less than the full length of the manifold. By controlling the length of the bond pad, the parasitic capacitance it contributes may be controlled. In applications such as a Doherty amplifier, this parasitic capacitance forms part of the quarter-wave transmission line of an impedance inverter, and hence directly impacts amplifier performance. In particular, by reducing the parasitic capacitance contribution from transistor output bond pads, the bandwidth of a Doherty amplifier circuit may be improved. At GHz frequencies and with state of the art transistor device feature sizes, concerns about phase mismatch between drain finger outputs are largely moot.
