  • Patent number: 12218051
    Abstract: Exemplary embodiments for redistribution layers of integrated circuit components are disclosed. The redistribution layers of integrated circuit components of the present disclosure include one or more arrays of conductive contacts that are configured and arranged to allow a bonding wave to displace air between the redistribution layers during bonding. This configuration and arrangement of the one or more arrays minimize discontinuities, such as pockets of air to provide an example, between the redistribution layers during the bonding.

  • Publication number: 20230387172
    Abstract: The present disclosure is directed to anchor structures and methods for forming anchor structures such that planarization and wafer bonding can be uniform. Anchor structures can include anchor layers formed on a dielectric layer surface and anchor pads formed in the anchor layer and on the dielectric layer surface. The anchor layer material can be selected such that the planarization selectivity of the anchor layer, anchor pads, and the interconnection material can be substantially the same as one another. Anchor pads can provide uniform density of structures that have the same or similar material.
