ABSTRACT The scalabilty of the titanium self-aligned silicide (Salicide) process is one of the main issues for sub-quarter micron technologies. The major difficulty is to achieve a low sheet resistance for very narrow polysilicon lines and highly doped S/D regions, without degrading the transistor performance. A preamorphization implant (PAl) performed before the titanium deposition, can achieve a low Ti silicide sheet resistance (
