发明名称 Method and apparatus for reducing tilt angle variations in an ion implanter
摘要 An ion beam implantation system. An ion beam is controllably deflected from an initial trajectory as it passes through spaced parallel that are biased by a control circuit. Once deflected, the ion beam enters an electrostatic lens that redeflects the once deflected ion beam. When the beam exits the lens it moves along a trajectory that impacts a workpiece. By controlled deflection of the beam multiple parallel beam paths result, all of which input the workpiece at a uniform impact angle.
