Claims14
A semiconductor package, comprising:
- a plurality of leads each having a bond pad at one end thereof, a free end at another end thereof, and an embedded portion disposed between said free end and said bond pad thereof embedded in a ceramic body, each said bond pad including a bond surface exposed at a first surface of said ceramic body and each said lead including an extending portion extending out and away from said ceramic body, said extending portion including said free end of said lead;
- a semiconductor device disposed over said ceramic body, said semiconductor device including a plurality of electrodes on a first surface thereof, said plurality of electrodes including a first power electrode, a second power electrode, and at least one control electrode, each electrode being electrically coupled to a respective exposed bond surface of a respective bond pad;
- an adhesive attaching said semiconductor device to said ceramic body;
- a plurality of electrical connectors each having one end electrically and mechanically connected to a respective electrode of said semiconductor device at said one end thereof and another end electrically and mechanically connected to a respective bond surface of a respective lead at said another end thereof;
- and
- a housing encapsulating at least said semiconductor device and said exposed surfaces of said bond pads, wherein said extending portion of each lead extends out and away from said housing, and wherein said free end of each said leads resides outside said ceramic body and said housing.
