Abstract: During ion implantation into a wafer, an ion beam current is measured, a change in vacuum conductance which changes in accordance with a change of the location of a structure operating in a vacuum beam line chamber or a vacuum treatment chamber is obtained, furthermore, changes in degree of vacuum at one or plural places are detected using a vacuum gauge installed in the vacuum beam line chamber or the vacuum treatment chamber. The amount of an ion beam current is corrected using the obtained vacuum conductance and the detected degree of vacuum at one or plural places, and the dose amount implanted into the wafer is controlled.

Abstract: An ion implantation method includes reciprocally scanning an ion beam, mechanically scanning a wafer in a direction perpendicular to the ion beam scanning direction, implanting ions into the wafer, and generating an ion implantation amount distribution in a wafer surface of an isotropic concentric circle shape for correcting non-uniformity in the wafer surface in other semiconductor manufacturing processes, by controlling a beam scanning speed in the ion beam scanning direction and a wafer scanning speed in the mechanical scanning direction at the same time and independently using the respective control functions defining speed correction amounts.
