ABSTRACT:
In an ion implantation system including (a) an ion source (b) a mass analyzing portion, (c) an ion acceleration portion, (d) an ion beam focusing/deflecting portion, and (e) an end station chamber for implanting ions onto a semiconductor substrate. The ion source consists of plural ion sources being connected to the same mass analyzing portion in which any one of the plural ion sources is selected. Mass-separated ions from the ion source are led to the acceleration portion, and a stencil mask is arranged approximately to the semiconductor substrate in the end station chamber.
