Singulation method for semiconductor package with plating on side of connectors
A method of singulating semiconductor packages, the method comprising: providing a plurality of semiconductor dies coupled to a single common leadframe, wherein a molding compound at least partially encases the semiconductor dies and the leadframe; singulating the plurality of semiconductor dies, wherein the leadframe is at least partially cut between adjacent semiconductor dies, thereby forming exposed side surfaces on leads of the leadframe; and plating the exposed side surfaces of the leads with a plating material, wherein the plating material is a different material than the leads. In some embodiments, singulating the plurality of semiconductor dies comprises performing a full cut of the leadframe. In some embodiments, singulating the plurality of semiconductor dies comprises performing separate partial cuts of the leadframe.
IC package with integrated inductor
In one implementation, a semiconductor package includes an integrated circuit (IC) attached to a die paddle segment of a first patterned conduct carrier and coupled to a switch node segment of the first patterned conductive carrier by an electrical connector. In addition, the semiconductor package includes a second patterned conductive carrier situated over the IC, a magnetic material situated over the second patterned conductive carrier, and a third patterned conductive carrier situated over the magnetic material. The second patterned conductive carrier and the third patterned conductive carrier are electrically coupled so as to form windings of an integrated inductor in the semiconductor package.
Power semiconductor module and composite module
A power semiconductor module includes a wiring member that electrically connects a front surface electrode of a semiconductor element and a circuit board of an insulating substrate in a housing. A resin provided in the housing covers the wiring member, and has a height in the vicinity of the wiring member.

HERMETIC PACKAGE FOR HIGH CTE MISMATCH
The present disclosure relates to a hermetic package capable of handling a high coefficient of thermal expansion (CTE) mismatch configuration. The disclosed hermetic package includes a metal base and multiple segments that are discrete from each other. Herein, a gap exists between every two adjacent ceramic wall segments and is sealed with a connecting material. The ceramic wall segments with the connecting material form a ring wall, where the gap between every two adjacent ceramic wall segments is located at a corner of the ring wall. The metal base is either surrounded by the ring wall or underneath the ring wall.
