Embedded bridge structure in a substrate

摘要

Some novel features pertain to a substrate that includes a first dielectric layer and a bridge structure. The bridge structure is embedded in the first dielectric layer. The bridge structure is configured to provide an electrical connection between a first die and a second die. The first and second dies are configured to be coupled to the substrate. The bridge structure includes a first set of interconnects and a second dielectric layer. The first set of interconnects is embedded in the first dielectric layer. In some implementations, the bridge structure further includes a second set of interconnects. In some implementations, the second dielectric layer is embedded in the first dielectric layer. The some implementations, the first dielectric layer includes the first set of interconnects of the bridge structure, a second set of interconnects in the bridge structure, and a set of pads in the bridge structure.
