Presenter: Muhannad Bakir


This presentation will discuss high-density multi-die integration approaches both in 2.5D and 3D, though we will emphasize 2.5D architectures. Specifically, we first discuss various 2.5D approaching including Heterogeneous Interconnect Stitching Technology (HIST), which enables the interconnection of multiple dice of various functionalities 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 multi-height 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 discuss highly-scaled 3D ICs using sub-micron TSVs and report fabrication and characterization results; we also discuss the impact of TSV geometry on 3D end-to-end interconnect links (energy and latency) accounting on-chip wire resistance and capacitance. Third, and lastly, we briefly discuss 3D IC applications in CMOS multimodal biosensors.
