A semiconductor device package includes a multi-layer substrate including a bottom layer and a top layer. One or more dies are mounted on and electrically coupled to the top layer of the substrate. An electromagnetic interference (EMI) shield encapsulates the substrate and the semiconductor dies. A first plurality of conductive stubs is positioned around edges of the top layer of the substrate. Each of the conductive stubs includes an edge portion having a first thickness and in contact with the EMI shield. A second plurality of conductive stubs is positioned around edges of the bottom layer of the substrate. Each of the second plurality of conductive stubs includes an edge portion having a second thickness less than the first thickness and in contact with the EMI shield.

Semiconductor device package having improved conductive stub coverage

A semiconductor package includes a substrate having a top planar surface and a semiconductor die mounted on the top planar surface of the substrate. Bond wires electrically connect the semiconductor die to the substrate. Flow control dams are integrally formed with the top planar surface of the substrate and each flow control dam protrudes from the top planar surface of the substrate at a location proximate to the bond wires. The flow control dams reduce the occurrence of wire sweep in the bond wires electrically connected to the substrate and semiconductor die.

Semiconductor device package mold flow control system and method

A semiconductor device package includes a first substrate having an electrical circuit, semiconductor dies stacked one on top of the other, and bond wires electrically connected one to another. The bond wires electrically couple the semiconductor dies to one another and to the electrical circuit. There is a first bond wire having a first portion connected to a first semiconductor die, a second portion connected to a second semiconductor die, and an intermediate portion between the first portion and second portion. The semiconductor device package further includes a molding compound encapsulating the semiconductor dies, and the first and second portions of the first bond wire. The intermediate portion of the first bond wire is exposed along a top planar surface of the molding compound. The semiconductor device package may be used for coupling one or more other semiconductor device packages thereto via the exposed intermediate portion.
