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: 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: Stitched die structures, and methods for interconnecting die are described. In an embodiment, a stitched die structure includes a semiconductor substrate that includes a first die area of a first die and a second die area of a second die separate from the first die area. A back-end-of-the-line (BEOL) build-up structure spans over the first die area and the second die area, and includes a first metallic seal directly over a first peripheral area of the first die area, a second metallic seal directly over a second peripheral area of the second die area, and a die-to-die routing extending through the first metallic seal and the second metallic seal to electrically connect the first die to the second die.

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: Flexible packages and electronic devices with integrated flexible packages are described. In an embodiment, a flexibly package includes a first die and a second die encapsulated in a molding compound layer. A compliant redistribution layer (RDL) spans the molding compound layer and both dies, and includes electrical routing formed directly on landing pads of the dies. A notch is formed in the molding compound layer between the dies to facilitate flexure of the compliant RDL.

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.
