Abstract:
1. A microelectronic package, comprising: a substrate having terminals thereon configured for electrical connection with a component external to the package; a first microelectronic element having a first face adjacent to and facing the substrate, a second face opposite the first face, and an edge extending between the first and second faces; a second microelectronic element having a face partially overlying and facing the second face of the first microelectronic element, a plurality of contacts on the face of the second microelectronic element being disposed beyond the edge of the first microelectronic element; a sheet-like heat spreader separating the first and second microelectronic elements, the heat spreader having an aperture, a first surface facing the second microelectronic element and peripheral edges bounding the first surface; connections extending through the aperture; and an overmold overlying the substrate and at least a portion of the first surface of the heat spreader, the overmold having a first overmold surface opposite the first surface of the heat spreader and peripheral edges extending away from the first overmold surface, wherein the heat spreader is exposed at at least one of the peripheral edges of the overmold, wherein the face of the second microelectronic element faces the heat spreader and is thermally coupled with the heat spreader, the contacts of the second microelectronic element are aligned with the aperture, and the terminals are electrically coupled together through the connections.
