Abstract: In one embodiment, an integrated circuit includes a heat generating structure within a dielectric region and one or more substantially horizontally arranged heat dissipation layers within the dielectric region. Each heat dissipation layer includes electrically inactive thermally conductive structures, at least two such structures in at least one such layer being substantially horizontally connected and thermally coupled to one another within the layer. The electrically inactive thermally conductive structures cooperate to facilitate dissipation of heat from the heat generating structure. In another embodiment, an integrated circuit includes one or more heat generating structures within a dielectric region and electrically inactive thermal posts formed at least partially within the dielectric region. At least one such post is substantially horizontally connected and thermally coupled to another such post.
