Abstract :
ULSI device construction is highly sensitive to particulate contamination. High current ion implantation is a significant source of particles, yet the kill rate of these particles is not well understood. This paper has found that particles 1μ or larger at implant kill die by blocking the implant with a 7% kill rate for particles added during ion implantation compared to a 15% kill rate for incoming particles. This suggests that the yield focus in implant should concentrate on particles larger than 1μ.
