Heat dissipation structures
The present disclosure describes heat dissipation structures formed in functional or non-functional areas of a three-dimensional chip structure. These heat dissipation structures are configured to route the heat generated within the three-dimensional chip structure to designated areas on or outside the three-dimensional chip structure. For example, the three-dimensional chip structure can include a plurality of chips vertically stacked on a substrate, a first passivation layer interposed between a first chip and a second chip of the plurality of chips, and a heat dissipation layer embedded in the first passivation layer and configured to allow conductive structures to pass through.
