Abstract:
1. A structure comprising: a first die having a first surface and a second surface, the second surface of the first die being opposite the first surface of the first die, respective ones of first conductive connectors being coupled to the first surface of the first die, and respective ones of second conductive connectors being coupled to the second surface of the first die; a second die having a first surface and a second surface, the second surface of the second die being opposite the first surface of the second die, respective ones of the first conductive connectors being coupled to the first surface of the second die, respective ones of the second conductive connectors being coupled to the second surface of the second die; a first interposer over the first die and the second die, a first surface of the first interposer being coupled to the first conductive connectors, a second surface of the first interposer being coupled to third conductive connectors; a third die over the first interposer, a first surface of the third die being coupled to respective ones of the third conductive connectors; and a fourth die over the first interposer, a first surface of the fourth die being coupled to respective ones of the third conductive connectors, wherein the first die is communicatively coupled to the second die through the first interposer, and/or the third die is communicatively coupled to the fourth die through the first interposer.
