Abstract:
1. A method of implanting ions onto a substrate using an ion beam and a variable aperture, the method comprising: obtaining a substrate, the substrate having non-uniform properties due to a previous deposition process; determining, by an ion implanting device, a first ion beam parameter for a first portion of the substrate and a different second ion beam parameter for a different second portion of the substrate in response to the non-uniform properties of the first portion and the properties of the second portion, respectively; 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 having the first ion beam parameter and applying the first shaped ion beam to the first portion of the substrate; and shaping the ion beam using the variable aperture to form a second ion beam having the second ion beam parameter and applying the second ion beam to the second portion of the substrate.
