TECHNIQUES FOR FORMING SEMICONDUCTOR DEVICE PACKAGES AND RELATED PACKAGES, INTERMEDIATE PRODUCTS, AND METHODS
Semiconductor device packages may include a first semiconductor device over a substrate and a second semiconductor device over the first semiconductor device. An active surface of the second semiconductor device may face away from the substrate. Electrical interconnections may extend from bond pads of the second semiconductor device, along surfaces of the second semiconductor device, first semiconductor device, and substrate to pads of routing members of the substrate. The electrical interconnections may include conductors in contact with the bond pads and the routing members and a dielectric material interposed between the conductors and the first semiconductor device, the second semiconductor device and the substrate between the bond pads and the pad of the routing members. An encapsulant distinct from the dielectric material may cover the electrical interconnections, the first semiconductor device, the second semiconductor device, and an upper surface of the substrate.

WIRING MEMBER AND SEMICONDUCTOR MODULE INCLUDING SAME
In a wiring member, an element connection portion, a plate connection portion, and an upper surface portion are at height positions different from one another. The element connection portion has a through hole, and the plate connection portion has a through hole and a chamfer. The upper surface portion which is not connected to another portion, has projections asymmetrically disposed on both side surfaces thereof. Owing to these features, the type, the orientation, and the front and the back of the wiring member can be easily distinguished. Accordingly, it is possible to prevent incorrect assembling of the wiring member in a semiconductor module.
