Patent ID: 8436458

Claim:
A microelectronic assembly, comprising: a substrate having oppositely-facing first and second surfaces and a first aperture extending between the first and second surfaces, the substrate further having a plurality of electrically conductive elements thereon; a first microelectronic element having a surface facing the first surface of the substrate, another surface remote therefrom, and an edge extending between the surfaces thereof; a second microelectronic element having a front surface facing the first microelectronic element, the second microelectronic element having a plurality of contacts exposed at the front surface thereof, the contacts of the second microelectronic element projecting beyond the edge of the first microelectronic element; signal leads connected to the contacts of the second microelectronic element and extending through the first aperture to at least some of the conductive elements on the substrate; and at least one power regulation component having active circuit elements therein disposed between the first surface of the substrate and the front surface of the second microelectronic element.
