    Abstract: Hybrid bonded multi-level die stacks, related apparatuses, systems, and methods of fabrication are disclosed. First-level integrated circuit (IC) dies and a base substrate each include hybrid bonding regions surrounded by hydrophobic structures. The hybrid bonding regions are brought together with a liquid droplet therebetween, and capillary forces cause the IC die to self-align. A hybrid bond is formed by evaporating the droplet followed by anneal. Hybrid bonding regions of second-level IC dies are similarly bonded to hybrid bonding regions on backsides of the first-level IC dies. This is repeated for any number of subsequent levels of IC dies. IC structures including the bonded IC dies and portions of the base substrate are segmented and assembled.

    Abstract: Methods of selectively transferring portions of layers between substrates, and devices and systems formed using the same, are disclosed herein. In one embodiment, a first substrate with a release layer and a layer of integrated circuit (IC) components over the release layer is received, and a second substrate with one or more adhesive areas is received. The release layer on the first substrate is weakened. The first substrate is partially bonded to the second substrate, such that a subset of IC components on the first substrate are bonded to the adhesive areas on the second substrate. The first substrate is then separated from the second substrate, and the subset of IC components bonded to the second substrate are separated from the first substrate and remain on the second substrate.

    Abstract: Embodiments include a mixed hybrid bonding structure comprising a composite dielectric layer, where the composite dielectric layer comprises an organic dielectric material having a plurality of inorganic filler material. One or more conductive substrate interconnect structures are within the composite dielectric layer. A die is on the composite dielectric layer, the die having one or more conductive die interconnect structures within a die dielectric material. The one or more conductive die interconnect structures are directly bonded to the one or more conductive substrate interconnect structures, and the inorganic filler material of the composite dielectric layer is bonded to the die dielectric material.

    Abstract: Integration of a side-radiating waveguide launcher system into a semiconductor package beneficially permits the coupling of a waveguide directly to the semiconductor package. Included are a first conductive member and a second conductive member separated by a dielectric material. Also included is a conductive structure, such as a plurality of vias, that conductively couples the first conductive member and the second conductive member. Together, the first conductive member, the second conductive member, and the conductive structure form an electrically conductive side-radiating waveguide launcher enclosing shaped space within the dielectric material. The shaped space includes a narrow first end and a wide second end. An RF excitation element is disposed proximate the first end and a waveguide may be operably coupled proximate the second end of the shaped space.

    Abstract: An integrated circuit assembly may be formed having a substrate, a first integrated circuit device electrically attached to the substrate, a second integrated circuit device electrically attached to the first integrated circuit device, and a heat dissipation device comprising at least one first thermally conductive structure proximate at least one of the first integrated circuit device, the second integrated circuit device, and the substrate; and a second thermally conductive structure disposed over the first thermally conductive structure(s), the first integrated circuit device, and the second integrated circuit device, wherein the first thermally conductive structure(s) have a lower electrical conductivity than an electrical conductivity of the second thermally conductive structure. The first thermally conductive structure(s) may be formed by an additive process or may be pre-formed and attached to at least one of the first integrated circuit device, the second integrated circuit device, and the substrate.
