## 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.
