Abstract:
1. A method of implanting different ion doses onto different portions of a substrate using an ion beam and a variable aperture, wherein the substrate has a first portion and a different second portion, the method comprising: producing the ion beam and directing the produced ion beam to the variable aperture; shaping the ion beam using the variable aperture to form a first shaped ion beam based on a first ion beam parameter, applying the first shaped ion beam to the first portion of the substrate, after the first shaped ion beam translates beyond the first portion of the substrate, translating the first shaped ion beam toward the second portion of the substrate; turning off the magnetic field at least momentarily while translating in between the first portion of the substrate and the second portion of the substrate; after applying the first shaped ion beam, directing the first shaped ion beam away from the substrate, and while directing the first shaped ion beam away from the substrate, shaping the ion beam using the variable aperture to form a second shaped ion beam based on a second ion beam parameter, applying the second shaped ion beam to the second portion of the substrate,
