WebIon implantation is a relatively newer doping technique that operates close to room temperature. It is a physical process of doping, not based on a chemical reaction. Because ion implantation takes place close to room temperature, it is compatible with conventional lithographic processes, so small regions can be doped. Webthe single wafer Optima High Current tools has demonstrated improved ion beam stability (50x reduction in glitches for BF 2) which can translate into decreased particles and improved ion source life (200 to 300 hours for dedicated BF 2).
