A redistribution layer (RDL) is an extra metal layer on an integrated circuit that makes its I/O pads available in other locations of the chip, for better access to the pads where necessary. When an integrated circuit is manufactured, it usually has a set of I/O pads that are wirebonded to the pins of the package. A redistribution layer is an extra layer of wiring on the chip that enables bond out from different locations on the chip, making chip-to-chip bonding simpler. Another exa… WebA redistribution layer (RDL) is used to reroute connections to desired locations. For example, a bump array located in the center of a chip can be redistributed to positions near the …
