Abstract:
1. 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 a plurality of electrically conductive elements thereon; a first microelectronic element having a rear surface and a front surface facing the dielectric element, the first microelectronic element having a plurality of contacts exposed at the front surface thereof; a second microelectronic element having a rear surface and a front surface facing the rear surface of the first microelectronic element, the second microelectronic element having a plurality of contacts exposed at the front surface and projecting beyond an edge of the first microelectronic element; signal leads connected to the first microelectronic element extending through the first aperture to some of the conductive elements on the dielectric element, and signal leads connected to the second microelectronic element extending through the second aperture to some of the conductive elements on the dielectric element; and an electrically conductive plane attached to the dielectric element and at least partially positioned between the first and second apertures, the conductive plane spanning an entire distance separating the first and second apertures, the electrically conductive plane being electrically connected with one or more of the contacts of each of the first and second microelectronic elements.
