3D interconnect optimization for single channel 100-GBps transmission in a photonic interposer

Résumé

High speed 3D interconnects are a key element in 2.5D interposer technology that is widely investigated for high performance applications. A wide-band electrical modeling and optimization method of the photonic interposer interconnect chains is presented using scalable models developed based on electromagnetic simulations. Resulting models enable fast and accurate assessment of the whole-chain performances for various sets of technology and design parameters. Using these tools, transmission of 100-Gbps signal through Back-end-of-Line (BEOL), Through Silicon Via (TSV) and Redistribution Layer (RDL) chains are improved following two different methods: independent optimization of each interconnect and optimization of the whole chain. Both techniques are compared for TSV-RDL chain case with wide-range parameter variation and for BEOLTSV-RDL path satisfying design and technology constraints. Optimization results are validated through comparison with 3DEM simulation, demonstrating the efficiency of proposed methods to optimize the entire 3D-chain. Results would lead to further works including eye-diagram opening and power consumption optimization, geometrical discontinuity modeling and optimized chain integration.
