Abstract
In order to achieve the high-speed operation of scaled CMOS devices, low source-drain and gate resistivity is required. However , an abrupt increase in TiSi2/polysilicon resistance occurs when the line width falls below 0.25μm. We analyze this degradation and indicate that NiSi is a suitable candidate to replace TiSi2, because in the case of NiSi no resistance degradation occurs.
