Abstract:
1. A stacked microelectronic device, comprising: a first interposer substrate having a first side and a second side facing away from the first side; a first microelectronic die attached to the first side of the first interposer substrate; a second interposer substrate having a first side facing away from the first microelectronic die and a second side facing the first microelectronic die, wherein the first microelectronic die is positioned between the first and second interposer substrates, wherein the first interposer substrate is electrically coupled to the first microelectronic die and to the second interposer substrate; a wire-bond connecting a periphery of the microelectronic die and the first interposer substrate; a third interposer substrate having a first side and a second side facing away from the first side, the second side facing the second interposer substrate; a second microelectronic die attached to the first side of the third interposer substrate; a fourth interposer substrate attached to the second microelectronic die, wherein the second microelectronic die is positioned between the third and fourth interposer substrates, wherein the third interposer substrate is electrically coupled to the second microelectronic die and the fourth interposer substrate; and an electrical coupling between the second and third interposer substrates.
