Abstract: An ion implanter to facilitate channeling of an ion beam into a crystalline structure of a workpiece is disclosed. The ion implanter comprises an ion source to generate an ion beam, a platen to support the workpiece having the crystalline structure, an Xray source to generate an Xray beam, wherein at least a portion of the Xray beam impacts the workpiece to produce diffracted Xrays, an Xray detector positioned to receive the diffracted Xrays, and a controller, in communication with the Xray source, the platen, and the Xray detector. The controller contains instructions, which enable the ion implanter to perform a rocking curve test after the workpiece is disposed on the platen and calculate an orientation of the platen for an ion implant process based on a result of the rocking curve test to facilitate channeling of the ion beam into the crystalline structure of the workpiece.
