A semiconductor device assembly includes a substrate and a semiconductor die adjacent to a first surface of the substrate. The substrate also includes a second surface opposite from the first surface, an opening extending from the first surface and the second surface, contact pads on the first surfa
A semiconductor device assembly includes a substrate and a semiconductor die adjacent to a first surface of the substrate. The substrate also includes a second surface opposite from the first surface, an opening extending from the first surface and the second surface, contact pads on the first surface, and substrate pads on the second surface, adjacent to the opening. Bond pads of the semiconductor die are aligned with the opening through the substrate. Intermediate conductive elements, such as bond wires, extend from bond pads of the semiconductor die, through the opening, to substrate pads on the opposite, second surface of the substrate. An encapsulant, which fills the opening and covers the intermediate conductive elements, protrudes beyond a plane in which the second surface of the substrate is located. Another electronic device, such as another semiconductor device package, may communicate electrically with the die of the semiconductor device assembly through the contact pads on the first surface of the substrate. In some embodiments, the other electronic device may be stacked with the semiconductor device assembly.
