摘要
利用侧墙图形转移实现亚 0 .1μm栅线条 ,重掺杂多晶硅做固相扩散源实现 CMOS晶体管超浅源漏扩展区 ,并且将二者有机结合起来 ,成功实现了栅长约为 84 .6 nm的 CMOS器件和电路 .报道了利用重掺杂多晶硅固相扩散同时实现 CMOS源漏扩展区的方法 .
A newly developed method of pattern shift with spacer is proposed to define sub 0 1μm MOS transistor gates.Polysilicon doped heavily is introduced as solid phase diffusion source to realize ultra shallow source and drain extensions.Using the process of integration of these two methods,which is basically compatible with standard process,the nanoscale devices and circuits with gate length of 84 6nm are fabricated with relatively good performance.
