Abstract:
1. A microelectronic assembly, comprising: a substrate having: a first microelectronic element having a front surface facing toward the first surface and bond pads at the front surface aligned with the first opening, a rear surface opposite from the front surface, and an edge extending between the front and rear surfaces; a second microelectronic element having a front surface facing toward the rear surface of the first microelectronic element and projecting beyond the edge of the first microelectronic element, and bond pads at the front surface of the second microelectronic element aligned with the second opening; and a plurality of terminals exposed at the second surface and electrically connected with the bond pads of the first and second microelectronic elements, the terminals configured for connecting the microelectronic assembly to at least one component external to the assembly, at least one of the terminals being disposed at least partially within the peripheral region such that a straight line extending in the first direction and passing through the at least one terminal passes through or over at least one of the openings, wherein the bond pads of the first and second microelectronic elements are electrically connected to conductive elements of the substrate, wherein the bond pads of the first microelectronic element are electrically connected to the conductive elements by first leads having portions aligned with the first opening, and the bond pads of the second microelectronic element are electrically connected to the conductive elements by second leads having portions aligned with the second opening, wherein the edge of the first microelectronic element is a first edge and the first microelectronic element has a second edge opposite therefrom, wherein the second microelectronic element has first and second opposed edges, and wherein each microelectronic element has at least one row of five or more of the bond pads extending in the first direction in a central region of the front surface thereof, each central region extending a middle third of a distance between the respective first and second edge, and wherein at least one of: the first leads do not extend through the first opening, or the second leads do not extend through the second opening.
