Patent ID: 8885356

Claim:
A microelectronic assembly comprising: a dielectric element having oppositely-facing first and second surfaces and first and second apertures extending between the surfaces, the dielectric element further having conductive elements thereon; a first microelectronic element having a rear surface and a front surface facing the first surface of the dielectric element, the first microelectronic element having a first edge and a plurality of contacts exposed at the front surface thereof; a second microelectronic element including having a rear surface and a front surface facing the rear surface of the first microelectronic element, a projecting portion of the front surface of the second microelectronic element extending beyond the first edge of the first microelectronic element, the projecting portion being spaced from the first surface of the dielectric element, the second microelectronic element having a plurality of contacts exposed at the projecting portion of the front surface; a plurality of first leads extending from contacts of the microelectronic elements through the at least one aperture to at least some of the conductive elements; an electrically conductive plane attached to the dielectric element and at least partially positioned between the first and second apertures, the electrically conductive plane being electrically connected with one or more of the contacts of at least one of the first or second microelectronic elements; a first passive component disposed between the projecting portion of the front surface of the second microelectronic element and the first surface of the dielectric element; a second passive component exposed at the second surface of the dielectric assembly and between the first and second apertures; a second lead extending from the first passive component to a contact of one of the microelectronic elements; and a circuit panel, wherein the dielectric element includes a plurality of terminals exposed at the second surface and electrically coupled to the circuit panel.
