摘要

提出了一种高温溅射原位硅化钛盐化新工艺。该工艺促进了TiSi/sub 2/相从C49向C54的转变,且没有团聚,从而在0.2 /spl mu/m栅极和0.4 /spl mu/m扩散层中实现了硅化。对于n/sup +/和p/sup +/硅化栅极,可以获得小于6/spl ω ///spl平方/的片电阻。利用原位硅化技术成功制备了有效沟道长度为0.09 /spl mu/m的CMOS晶体管。

Sub-quarter micron titanium salicide technology with in-situ silicidation using high-temperature sputtering
A new titanium (Ti) salicide technology with in-situ silicidation using high-temperature sputtering has been developed. This process enhances TiSi/sub 2/ phase transition from C49 to C54 without agglomeration, which results in achieving silicidation in 0.2 /spl mu/m gates and 0.4 /spl mu/m diffusion layers. A sheet resistance less than 6/spl Omega///spl square/ can be obtained for both n/sup +/ and p/sup +/ silicide gates. CMOS transistors having 0.09 /spl mu/m effective channel length were successfully formed using the in-situ silicidation technique.
