Abstract: With the development of silicon process size to the level of single nano, it has been more and more difficult to continue Moore's law. Advanced packaging solutions with heterogeneous integration, such as 2D Flip-Chip, 2.5D and 3D, will continue to meet market requirements for miniaturization, high performance and low cost, thus become the main direction of continuing Moore's Law. But it also presents new challenges, especially for system-level LVS checking. In this paper, Cadence Integrity 3D-IC tool was used to perform system-level LVS checking for different types of advanced packaging, which fully verified the effectiveness and practicability of the tool and ensured the reliability of heterogeneous integration packaging system solutions.
Key words : heterogeneous integration;advanced packaging;system-level LVS;integrity 3D-IC

0 引言

电子产品一直以来追求的尺寸更小,成本和功耗更低的趋势,在过去受益于硅工艺的快速升级更新,得到了持续的发展。但近年来,随着硅工艺尺寸发展到单纳米水平,摩尔定律的延续越来越困难。单一的纳米工艺在综合考虑成本、良率、功耗等因素后,将不再具有竞争优势。2D Flip-Chip、2.5D、3D等具有异构集成先进封装解决方案将继续满足小型化、高性能、低成本的市场需求,成为延续摩尔定律的主要方向。但它也提出了新的挑战,特别是对于系统级的LVS(Layout Versus Schematics)检查。由于异构集成封装结构复杂、规模庞大,任何一个环节的失误都会产生巨大的影响,因此急需一个完整的解决方案,可以对各类异构集成封装进行有效的系统级检查。本文尝试采用Cadence公司的Integrity 3D-IC平台,针对主流的异构集成封装进行LVS检查验证。
