摘要

本文提出了一种金属栅极集成的新方案,通过向功功能金属(WFM)中注入金属成分和离子(I/I)来实现精确的阈值电压(VTH)控制和多个VTH控制。在此基础上,采用原位阻挡金属进行WFM全填充,可以满足亚10nm节点栅极的电导要求。

Threshold voltage tuning by metal gate work function modulation for 10 nm CMOS integration and beyond
This paper describes a novel scheme of metal gate integration to achieve precise threshold voltage (VTH) control and multiple VTH, by using metal composition and ion implantation (I/I) into work function metal (WFM). Moreover, WFM full fill is demonstrated with in situ barrier metal to satisfy the conductance requirement of sub-10 nm node gate.
