Channel structure design, fabrication and carrier transport properties of strained-Si/SiGe-on-insulator (strained-SOI) MOSFETs

摘要

This paper reviews the current critical issues regarding the device design of strained-Si MOSFETs and demonstrates that strained-Si-on-insulator (strained-SOI) structures can effectively solve these problems. The advantages, characteristics and challenges of strained-SOI CMOS technology are presented, on the basis of our recent results. Furthermore, a future possible direction of channel engineering using strained-Si/SiGe structures, into the deep sub-100 nm regime, is addressed.
