  • Publication number: 20230395526
    Abstract: Some implementations described herein provide techniques and apparatuses for a semiconductor package. The semiconductor package, which may correspond to a high performance computing package, includes a reinforcement structure that is embedded in a substrate of the semiconductor package. The reinforcement structure may increase a rigidity of the semiconductor package so that a warpage is reduced and a coplanarity between the substrate and a printed circuit board is maintained during a surface mount process. Reducing the warpage may increase a robustness of connection structures between an interposer and the substrate. Additionally, maintaining the coplanarity reduces a likelihood that connection structures at a bottom surface of the substrate will fail to adequately solder or attach to lands of the printed circuit board during the surface mount process.

  • Publication number: 20230395443
    Abstract: A semiconductor package, which may correspond to a high-performance computing package, includes an interposer, a substrate, and an integrated circuit device between the interposer and the substrate. The integrated circuit device, which may correspond to an integrated passive device, is attached to the interposer within a cavity of the interposer. Attaching the integrated circuit device within the cavity of the interposer creates a clearance between the integrated circuit device and the substrate. In this way, a likelihood of the integrated circuit device contacting the substrate during a bending and/or a deformation of the semiconductor package is reduced. By reducing the likelihood of such contact, damage to the integrated circuit device and/or the substrate may be avoided to increase a reliability and/or yield of the semiconductor package.

  • Publication number: 20230386988
    Abstract: Semiconductor packages and methods of fabricating semiconductor packages include bonding structures on a surface of an interposer having non-uniform height dimensions in different regions of the interposer. A plurality of solder connections may contact the pillars and electrically connect the respective pillars of the interposer to corresponding bonding structures on a package substrate. The variation in the heights of the pillars in different regions of the interposer may compensate for warping of the interposer and improve the reliability of the electrical connections between the interposer and the package substrate.
