摘要:

隨著芯片在通信、汽車電子與高性能計算等領域的深入應用，低功耗、高性能的芯片需求持續上升。在摩爾定律推動下，器件微型化帶來量子隧穿效應和布線電阻增加等挑戰，尤其在5 nm及以下工藝節點，芯片互連成為性能瓶頸。Cu互連面臨尺寸效應導致的電阻激增，推動對新型低電阻材料的探索。綜述了集成電路互連在先進節點下的核心挑戰，分析Co、Ru等替代金屬及二元合金、拓撲半金屬、二維材料的發展前景，并探討人工智能在互連材料設計中的應用，為工業界開發新一代互連材料提供參考路徑。

Abstract:

With the increasing integration of chips into communications, automotive electronics and high-performance computing, the demand for low-power and high-performance devices continues to grow. Driven by Moore’s Law, the device miniaturization presents critical challenges such as quantum tunneling effects and increased wiring resistance. With technology nodes of 5 nm and below, the interconnects have emerged as a key performance bottleneck. Particularly, the copper interconnects face significant resistance increases due to size effects, driving the search for novel low-resistivity materials. This review summarizes the major challenges of interconnect technology at advanced nodes. In details, the potential applications of alternative metals such as cobalt and ruthenium, binary alloys, topological semimetals and two-dimensional materials are evaluated. At the same time, we also explores the application of artificial intelligence in interconnect material design, providing strategic insights for the development of next-generation interconnect solutions in the semiconductor industry.
