Abstract
This paper describes a new one-step annealing TiSi/sub 2/ process which achieves a 0.2 /spl mu/m line silicidation without causing the agglomeration and uncompleted phase transition failure. The process consists of i) one-step silicidation at over 800/spl deg/C which reduces C49-to-C54 phase transition temperature and ii) TiSi/sub 2/ over-growth control by a thin Ti and pre-amorphized Si reaction.<>
