Abstract:
1. A microelectronic assembly comprising: a first microelectronic element having a front surface, first contacts exposed at the front surface, a rear surface opposite the front surface, and a first edge surface extending between the front and rear surfaces; a second microelectronic element having a front surface, second contacts exposed at such front surface, a rear surface opposite such front surface, and a second edge surface extending between the front and rear surfaces, the first and second microelectronic elements attached to one another with the rear surfaces of the first and second microelectronic elements facing one another; a layer extending between the rear surfaces of the first and second microelectronic elements; at least one bridging element extending between at least one of the first contacts and at least one of the second contacts so as to electrically connect the two, wherein the at least one first contact and the at least one second contact remain exposed for electrically connecting the microelectronic assembly to a substrate external to the microelectronic assembly, the at least one bridging element extending as a continuous trace along the first and second edge surfaces and along a surface of the layer between the rear surfaces of the first and second microelectronic elements, wherein the layer provides electrical isolation between the at least one bridging element and the bodies of the microelectronic elements.
