An ion source for an ion implantation system is configured to form an ion beam from a predetermined species along a beamline, where the ion beam is at an initial energy. A deceleration component is configured to decelerate the ion beam to a final energy that is less than the initial energy. A workpiece support is configured to support a workpiece along a workpiece plane downstream of the deceleration component along the beamline. A beamline component is positioned downstream of the deceleration component along the beamline. The beamline component has a feature that is at least partially impinged by the ion beam, and where the feature has a surface having a predetermined angle of incidence with respect to the ion beam. The predetermined angle of incidence provides a predetermined sputter yield of the ion beam at the final energy that mitigates deposition of the ion species on the beamline component.

A system and method for creating various dopant concentration profiles using a single implant energy is disclosed. A plurality of implants are performed at the same implant energy but different tilt angles to implant ions at a variety of depths. The result of these implants may be a rectangular profile or a gradient profile. The resulting dopant concentration profile depends on the selection of tilt angles, doses and the number of implants. Varying tilt angle rather than varying implant energy to achieve implants of different depths may significantly improve efficiency and throughput, as the tilt angle can be changed faster than the implant energy can be changed. Additionally, this method may be performed by a number of different semiconductor processing apparatus.
