Abstract

This paper presents a complete 90nm CMOS technology platform dedicated to advanced SoC manufacturing, featuring 16/spl Aring/ EOT-70nm transistors (standard process) or 21/spl Aring/-90nm transistors (Low Power process) as well as 2.5 or 3.3V I/O transistors, copper interconnects and SiOC low-k IMD (k=2.9). The main critical process steps are described and electrical results are discussed. Moreover, using advanced lithographic tools, fully functional 1 Mbit SRAM instances, based on a highly manufacturable 6T 1.36/spl mu/m/sup 2/ memory cell, have been processed. The cell is detailed and its features, both electrical and morphological, are discussed.

经过验证的90nm CMOS技术平台,具有低k铜互连,适用于先进的片上系统(SoC)
本文提出了一个完整的90nm CMOS技术平台,专门用于先进的SoC制造,具有16/spl Aring/ EOT-70nm晶体管(标准工艺)或21/spl Aring/-90nm晶体管(低功耗工艺)以及2.5或3.3V I/O晶体管,铜互连和SiOC低k IMD (k=2.9)。叙述了主要的关键工艺步骤,并讨论了电学结果。此外,使用先进的光刻工具,基于高度可制造的6t1.36 /spl mu/m/sup 2/存储器单元,已经处理了全功能的1mbit SRAM实例。详细介绍了该细胞的电学和形态学特征。
