Abstract:
A substrate with an embedded stacked through-silicon via die is described. For example, an apparatus includes a first die and a second die. The second die has one or more through-silicon vias disposed therein (TSV die). The first die is electrically coupled to the TSV die through the one or more through-silicon vias. The apparatus also includes a coreless substrate. Both the first die and the TSV die are embedded in the coreless substrate.

Various embodiments are generally directed to an electronic assembly comprising at least two dies stacked on top of each other. Metal columns of different heights electrically connect the dies to a system substrate.
Abstract:
A semiconductor package can include a semiconductor die having an integrated circuit, a first die surface, and an opposite second die surface. A packaging can be attached to the die and have a holder surface opposite the first die surface. A heat spreader can be configured to cover the second die surface and the packaging surface and can be attached thereto by a layer of adhesive positioned between the heat spreader and the semiconductor die. A semiconductor package array can include an array of semiconductor dies and a heat spreader configured to cover each semiconductor die. A conductive lead can be electrically connected to the integrated circuit in a semiconductor die and can extend from the first die surface. Manufacturing a semiconductor package can include applying thermally conductive adhesive to the heat spreader and placing the heat spreader proximate the semiconductor die.
