An integrated circuit (IC) package with stacked die wire bond connections has two stacked IC dies, where a first die couples to a metallization structure directly and a second die stacked on top of the first die connects to the metallization structure through wire bond connections. The IC dies are coupled to one another through an interior metal layer of the metallization structure. Vias are used to couple to the interior metal layer.

A semiconductor device package includes a mechanical support structure that provides mechanical support to a stack of dies, where the dies are laterally offset from each other. The support structure has a sloped surface that is disposed at a non-perpendicular and non-parallel angle to other surfaces of the mechanical support structure. Electrical contacts are disposed on the sloped surface of the mechanical support structure for electrically interfacing with the stacked dies and on a different surface of the mechanical support structure for electrically interfacing with a substrate.

A printed circuit board includes a first insulating layer; an external connection pad embedded in a first surface of the first insulating layer and having a first externally exposed surface disposed at substantially the same level as the first surface of the first insulating layer; a second insulating layer disposed on a second surface of the first insulating layer and having a first surface in contact with the second surface of the first insulating layer; and a first wiring pattern embedded in the second insulating layer and exposed from the first surface of the second insulating layer to be in contact with a second externally exposed surface of the external connection pad opposing the first externally exposed surface.

Integrated circuit packaging with cavities and methods of manufacturing the same are disclosed. An example apparatus includes a semiconductor die and a housing enclosing portions of the semiconductor die. The housing defines an opening that extends from a surface of the semiconductor die to an external environment, the housing formed of a first material. The example apparatus includes a second material disposed within the opening to block exposure of the semiconductor die to the external environment.

A method for forming a board assembly includes identifying a location of a hot-spot on a semiconductor die and cutting an opening in a circuit board corresponding to the location of the identified hot-spot.

The semiconductor die is placed over the layer of thermally conductive paste such that the CVDD window underlies the hot-spot and such that a surface of the semiconductor die is in direct contact with the layer of thermally conductive paste.
