ABSTRACT:
A serial wafer processing type ion implantation system and method suitable for small production of many product types. The ion implantation method implants ions while a first wafer group including at least one or more wafers is rotated along a first orbital path intersecting with a path of an ion beam and while a second wafer group including at least one or more wafers is rotated along a second orbital path intersecting with the path of the ion beam, at least a portion of the second orbital path being different from the first orbital path.
