Abstract: Electronic package structures and systems are described in which a 3D interconnect structure is integrated into a package redistribution layer and/or chiplet for power and signal delivery to a die. Such structures may significantly improve input output (IO) density and routing quality for signals, while keeping power delivery feasible.

Abstract: Multi-die structures and methods of fabrication are described. In an embodiment, a multi-die structure includes a first die, a second die, and die-to-die routing connecting the first die to the second die. The die-to-die interconnection may be monolithically integrated as a chip-level die-to-die routing, or external package-level die-to-die routing.

Abstract: Chip sealing structures and methods of manufacture are described. In an embodiment, a chip structure includes a main body area formed of a substrate, a back-end-of-the-line (BEOL) build-up structure spanning over the substrate, and chip edge sidewalls extending from a back surface of the substrate to a top surface of the BEOL build-up structure and laterally surrounding the substrate and the BEOL build-up structure. In accordance with embodiments, the chip structure may further include a conformal sealing layer covering at least a first chip edge sidewall of the chip edge sidewalls and a portion of the top surface of the BEOL build-up structure, and forming a lip around the top surface of the BEOL build-up structure.

Abstract: Double side mounted package structures and memory modules incorporating such double side mounted package structures are described in which memory packages are mounted on both sides of a module substrate. A routing substrate is mounted to a bottom side of the module substrate to provide general purpose in/out routing and power routing, while signal routing from the logic die to double side mounted memory packages is provided in the module routing. In an embodiment, module substrate is a coreless module substrate and may be thinner than the routing substrate.
