报告内容: 2.5D 和 3D 集成电路的可靠性与信号完整性分析和优化
报告人简介: As a leading contender of more‐than‐Moore technology, 2.5D/3D integrated circuits are built by stacking multiple homogeneous and heterogeneous dies and connecting them with high density inter‐die vias. Such an aggressive integration leads to many‐fold improvement in interconnection length and footprint. The industry now is working relentlessly to build advanced multi‐chip solutions that satisfy the ever‐ demanding memory bandwidth and energy efficiency requirements in datacenter servers, self‐driving automobiles, and low‐power mobile devices. However, the high‐ power devices packed under a small footprint raise various reliability concerns including power delivery, heat dissipation, and noise coupling. In this talk, I will present CAD and design techniques to enhance electro‐power‐thermal reliability of 2.5D and 3D ICs. First, I will introduce a CAD platform that evaluates and optimizes power and thermal reliability for 3D memory cubes and 3D multi‐core processors. Next, I will present various methodologies for extracting and optimizing new parasitic elements in face‐to‐ back and face‐to‐face 3D ICs as well as 2.5D wafer‐level package. I will conclude with my collaborative research with the NSF POETS center at the University of Arkansas on design automation for multi‐chip power electronics.
