Abstract:
1. A system for implanting ions in a workpiece, the system comprising: a beam generating component for generating an ion beam; a mass resolving component for mass resolving the ion beam; a sweeping component positioned downstream of the mass resolving component for sweeping the ion beam up and/or down an entirety of the workpiece along a sweeping axis; a resolving aperture upstream of the workpiece and downstream of the sweeping component, and configured to move synchronously with the sweeping movement of the ion beam across the entirety of the workpiece so that desired ions of the ion beam pass therethrough, but contaminants are blocked thereby; and an endstation configured to support the workpiece for implantation thereof, wherein the endstation is configured to tilt the workpiece along a beam axis synchronously with the sweeping motion of the ion beam so that a substantially constant implantation angle is maintained over the workpiece.
