    Abstract: In one embodiment, a selective layer transfer process includes forming a layer of integrated circuit (IC) components on a first substrate, forming first bonding structures on a second substrate, and partially bonding the first substrate to the second substrate, which includes bonding a first subset of IC components on the first substrate to respective bonding structures on the second substrate. The process also includes forming second bonding structures on a third substrate, where the second bonding structures are arranged in a layout that is offset from the layout of the second substrate. The process further includes partially bonding the first substrate to the third substrate, which includes bonding a second subset of IC components on the first substrate to respective bonding structures on the third substrate.

    Abstract: A surface finish on an integrated circuit (IC) die structure or a substrate structure to which an IC die structure is to be bonded has a chemical composition distinct from that of underlying metallization. The surface finish may comprise a Cu—Ni alloy. Optionally, the Cu—Ni alloy may further comprise Mn. Alternatively, the surface finish may comprise a noble metal, such as Pd, Pt, or Ru or may comprise self-assembled monolayer (SAM) molecules comprising Si and C. During the bonding process a biphilic surface on the IC die structure or substrate structure may facilitate liquid droplet-based fine alignment of the IC die structure to a host structure. Prior to bonding, the surface finish may be applied upon a top surface of metallization features and may inhibit oxidation of the top surface exposed to the liquid droplet.

    Abstract: An integrated circuit structure may be formed having a substrate, at least one integrated circuit device embedded in and electrically attached to the substrate, and a heat dissipation device in thermal contact with the integrated circuit device, wherein a first portion of the heat dissipation device extends into the substrate and wherein a second portion of the heat dissipation device extends over the substrate. In one embodiment, the heat dissipation device may comprise the first portion of the heat dissipation device formed from metallization within the substrate.

    Abstract: A conformal power delivery structure, a three-dimensional (3D) stacked die assembly, a system including the 3D stacked die assembly, and a method of forming the conformal power delivery structure. The power delivery structure includes a package substrate, a die adjacent to and electrically coupled to the package substrate; a first power plane adjacent the upper surface of the package substrate and electrically coupled thereto; a second power plane at least partially within recesses defined by the first power plane and having a lower surface that conforms with the upper surface of the first power plane; and a dielectric material between the first power plane and the second power plane.

    Abstract: A microelectronics package comprising a package core and an inductor over the package core. The inductor comprises a dielectric over the package core. The dielectric comprises a curved surface opposite the package core. At least one conductive trace is adjacent to the package core. The at least one conductive trace is at least partially embedded within the dielectric and extends over the package core. A magnetic core cladding is over the dielectric layer and at least partially surrounding the conductive trace.
