摘要

3D单片集成(3DMI)技术提供了非常高密度的垂直互连和低寄生。以前的3DMI设计方法提供单元对单元或晶体管对晶体管集成。在本文中,我们提出了三维缓冲单元(3DCoB)作为一种新的3DMI设计方法。我们的方法提供了一个与传统2D工具完全兼容的签名物理实现流程。我们在一组使用28nm-FDSOI技术的基准电路上实现了我们的方法。签名性能结果显示,与相同的2D设计相比,改进了35%。

3DCoB: A new design approach for Monolithic 3D Integrated circuits
3D Monolithic Integration (3DMI) technology provides very high dense vertical interconnects with low parasitics. Previous 3DMI design approaches provide either cell-on-cell or transistor-on-transistor integration. In this paper we present 3D Cell-on-Buffer (3DCoB) as a novel design approach for 3DMI. Our approach provides a fully compatible sign-off physical implementation flow with the conventional 2D tools. We implement our approach on a set of benchmark circuits using 28nm-FDSOI technology. The sign-off performance results show 35% improvement compared to the same 2D design.
