摘要
We have developed a novel junction profile engineering using thin sidewall structure and applied it to sub-40 nm uniaxial strained CMOS devices. This transistor used a high-k thin sidewall with electrical charge in achieving a higher drive current with keeping the short channel effect. Consequently, the 18.5/15.6 % reduction of parasitic resistance achieve the 8.2/13.0 % improvement in the saturation current (I-on) at 38 nm gate length for nMOS and pMOS. In addition, I-on dependence on active width (W.) for pMOS is very small. In the size of active width : 0.1 mu m, a 42 % of I-on enhancement gave us I-on=680 mu A/mu m at V-dd=1 V. These characteristics are originated from formation of inversion layer and suppressing channeling penetration of pocket impurities implanted. A high performance Bulk nMOS and pMOS were demonstrated with I-on of 1069 mu A/mu m and 725 mu A/mu m at V-dd=1 V / I-off=100 nA/mu m, respectively.
