View Patent ↗Some embodiments include apparatus, systems, and methods having a base, a first die, a second arranged in a stacked with the first die and the base, and a structure located in the stack and outside at least one of the first and second dice and configured to transfer signals between the base and at least one of the first and second dice.
1. A method comprising:
arranging a first die in a stack with a second die, the first die including first conductive paths at least partly through the first die, wherein the second die includes a portion directly above the first die;
arranging an interposer between the first die and the second die, the interposer including second conductive paths coupled to the first die and the second die, wherein the interposer includes a via directly below the portion of the second die and directly above the first die, and one of the second conductive paths passes through the via, the interposer includes a length measured between edges of the interposer, and the length of the interposer is greater than a length of the first die;
arranging a structure portion on a side of the first die, the structure portion including conductive paths coupled to the second die wherein the structure portion is a first structure portion, the first structure portion including a first surface, a second surface opposite from the first surface, first conductive contacts located at the first surface, and second conductive contacts located at the second surface, and wherein the conductive paths in the first structure portion couple the first conductive contacts to the second conductive contacts; and
arranging a second structure portion on a second side of the first die, the second structure including a first surface, a second surface opposite from the first surface, first conductive contacts located at the first surface of the second structure portion, second conductive contacts located at the second surface of the second structure portion, wherein the conductive paths included in the second structure portion couple the first conductive contacts at the first surface of the second structure portion to the second conductive contacts at the second surface of the second structure portion.
2. The method of claim 1 , wherein the first structure portion includes vias, and the conductive paths in the first structure portion include conductive material inside the vias.
3. The method of claim 2 , wherein the second structure portion includes vias, and the conductive paths conductive paths in the second structure portion include conductive material inside the via.
4. The method of claim 1 , further comprising:
arranging a base in the stack, the base including an organic material and conductive paths through the organic material.
5. The method of claim 1 , wherein the interposer includes an additional via extending from a first surface to a second surface of the interposer, at least a portion of one of the second conductive paths passing through the via.
6. The method of claim 1 , wherein the interposer includes multiple layers, each of the multiple layers including at least one conductive potions coupled to at least one of the second conductive paths.
7. The method of claim 1 , wherein the interposer includes a first conductive portion coupled to a first selected conductive path of the second conductive paths, and a second conductive potion coupled to a second selected conductive path of the second conductive paths, at least one of the first and second conductive portions extending in a dimension perpendicular to the first and second selected conductive paths.
8. The method of claim 7 , wherein the first selected conductive path goes through a via that only extends partly through the interposer.
9. The method of claim 8 , wherein the second selected conductive path goes through an additional via that only extends partly through the interposer.
10. The method of claim 9 , wherein the first die includes a conductive segment inside the first die and coupled to a selected conductive path of the first conductive paths, the conductive segment extending in a dimension perpendicular to the selected conductive path.
11. The method of claim 1 , wherein arranging the interposer between the first die and the second die is performed such that the first die is outside the interposer.
12. The method of claim 11 , wherein arranging the interposer between the first die and the second die is performed that the second die is outside the interposer.
