This presentation will discuss high-density multi-die integration approaches both in 2.5D and 3D ICs. Specifically, we first discuss various 2.5D approaching including Heterogeneous Interconnect Stitching Technology (HIST), which enables the interconnection of multiple dice of various functionalities (including photonics) in a manner that mimics monolithic-like performance, yet utilizes advanced off-chip interconnects and packaging to provide flexibility in IC fabrication and design, improved scalability, reduced development time, and reduced cost. A key feature of HIST is the ability to place a 'stitch chip' between adjacent ICs on the surface of an organic/ceramic package and use I/Os to interface the active dice to the package and stitch chips simultaneously. Design considerations and benchmarking (power delivery, signaling, and thermal) will be described and experimental demonstrations will be shown. Secondly, we demonstrate embedded microfluidic cooling in 3D ICs along with TSV integration approaches; a 28nm FPGA with monolithic microfluidic cooling along with its performance benefits will also be discussed. Third, and lastly, we discuss 3D IC applications in CMOS multimodal biosensors.
