Patent ID: 7485969

Claim:
A packaged microelectronic device, comprising: a support member having support member circuitry including a first side, a second side opposite the first side, a plurality of first support member contacts and a plurality of second support member contacts at the first side, and a plurality of support member pads at the second side; a first known good microelectronic die attached to the support member, the first die including an active side and a back side opposite the active side, a first terminal at the active side, integrated circuitry electrically coupled to the first terminal, and a first redistribution structure at the active side of the first die and electrically coupled to the first terminal and the support member circuitry, wherein the first redistribution structure redistributes the signals from the first terminal to a larger array of first contacts; a second known good microelectronic die having an active side and a back side opposite the active side, wherein the second die is attached to the first die in a stacked configuration such that the back side of the second die is facing the support member, the second die including a second terminal at the active side, integrated circuitry electrically coupled to the second terminal, a second redistribution structure at the active side of the second die and electrically coupled to the second terminal and the support member circuitry, and a plurality of electrical couplers attached to the second redistribution structure, wherein the second redistribution structure redistributes the signals from the second terminal to a larger array of second contacts; and a casing covering the first die, the second die, and at least a portion of the support member.
