Claim Text:
1. An ion implantation system, comprising: an ion source configured to form an ion beam; a mass analyzer configured to mass analyze the ion beam; an ion beam scanner configured to scan the ion beam along a first axis, therein defining a scanned ion beam; a workpiece support configured to support a workpiece thereon; an angular implant apparatus, wherein the angular implant apparatus is configured to vary an angle of incidence of the scanned ion beam relative to the workpiece along a second axis; and a controller configured to control the angular implant apparatus, wherein the controller is configured to vary the angle of incidence of the scanned ion beam relative to the workpiece concurrent with the scanned ion beam impacting the workpiece, wherein the angular implant apparatus comprises an angular energy filter positioned downstream of the ion beam scanner, and wherein the controller is configured to vary an input to the angular energy filter, therein varying the angle of incidence of the scanned ion beam relative to the workpiece concurrent with the scanned ion beam impacting the workpiece.
