Abstract:
1. A microelectronic assembly, comprising: a first microelectronic element having a front surface and a first electrically conductive pad exposed at the front surface, and a first electrically conductive element extending along the front surface away therefrom; a second microelectronic element having a front surface facing the front surface of the first microelectronic element, and a second electrically conductive pad exposed at the front surface and juxtaposed with a portion of the first electrically conductive element, the first and second microelectronic elements embodying active semiconductor devices; a second electrically conductive element extending within an opening extending from a rear surface of the first microelectronic element towards the front surface thereof, the second electrically conductive element contacting the first electrically conductive pad; and a third electrically conductive element extending within an opening extending from a rear surface of the second microelectronic element towards the front surface thereof, the third conductive element extending through an opening in the second conductive pad and contacting the second electrically conductive pad and the first electrically conductive element, the first electrically conductive element extending in a lateral direction along the front surface of the first microelectronic component from the first electrically conductive pad toward the third electrically conductive element.
