Wafer-on-Wafer Hybrid Bonding: Reticle Placements To Achieve Efficient NW Topologies (ETH Zurich)

Researchers from ETH Zurich have published a technical paper on "Network Design for Wafer-Scale Systems with Wafer-on-Wafer Hybrid Bonding." They explore how wafer-on-wafer bonding can enhance communication bandwidth in large language models. By strategically placing reticles on wafers, they achieve network topologies that improve throughput by up to 250%, reduce latency by up to 36%, and decrease energy consumption per transmitted byte by up to 38%. The study offers insights into optimizing communication performance in wafer-scale systems.
