Abstract

An ion implantation apparatus for integrated circuit manufacturing is disclosed. In an apparatus in accordance with an embodiment of the invention, a current detector detects a current flowing to a turbo pump. A display displays information about the detected current, and a controller determines whether the detected current is within a specified range. If the detected current is not within the specified range, the controller issues a power control signal to, stop the turbo pump. At this time, the controller also stops an ion implantation of the apparatus.
