  • Publication number: 20230395438
    Abstract: A semiconductor device includes a die stack having dies selected into the stack based on their thicknesses. After the dies are formed on a wafer and thinned, a metrology tool is used to determine the thicknesses of the dies in the wafer. These thicknesses are stored in a known thickness die (KTD) map, along with other information such as their standard and average deviations and their classification into a binning class. In one example, dies which have been classified into bin 1 (having an optimal thickness) are selected to provide a high capacity highly reliable semiconductor device. In a further example, dies of different bins are mixed and matched to provide a uniform, highly controlled overall die stack height.

  • Patent number: 11257785
    Abstract: A semiconductor device is disclosed including a multi-module interposer for enabling communication between one or more semiconductor dies within the device and a host device on which the semiconductor device is mounted. The multi-module interposer may be formed at the wafer level, and provides fan-out signal paths to and from the one or more dies in the device. Additionally, the multi-module interposer allows any of a variety of different semiconductor packaging configurations to be formed at the wafer level, including for example wire bonded packages, flip chip packages and through silicon via (TSV) packages.

  • Publication number: 20220052002
    Abstract: Systems, methods, and devices for 3D packaging. In some embodiments, a semiconductor package includes a first die and a second die. The first die includes a first bonding pad on a top of the first die and near a first edge of the first die. The second die includes a second bonding pad on a top of the second die and near a second edge of the second die. A pillar is located on the second bonding pad. The first die is mounted on top of the second die such that the first edge is parallel to the second edge and offset from the second edge such that the pillar is exposed. A wire is bonded to a bonding surface of the pillar and bonded to a bonding surface of the first bonding pad.
