In this chapter, thermal challenges in heterogeneous three‐dimensional (3D) and 2.5D die integration architectures are briefly summarized. To solve these challenges, interposer‐ and tier‐embedded microfluidic cooling technologies are proposed in conjunction with thermal isolation technologies. Two novel architectures for 3D and 2.5D integration are proposed and thermally evaluated through modeling and experimental demonstrations. Moreover, to address off‐chip signaling ...
