Webenergy (sub-keV) ion implantation with high beam current is required for shallow junction formation. Due to space charge limits in low energy ion beam transport, it is necessary to extract an ion beam at higher energy (>1keV) and decelerate them to a target energy, for example 700eV before the beam impacts the wafer.
