An ion implanter accelerates dopant ions into a semiconductor wafer to change the electrical properties of near-surface regions.
A high-current implanter class is used when a fabrication flow needs substantial dopant throughput for implantation steps.
The tool belongs downstream of wafer preparation and upstream of subsequent process modules that complete the implanted device region.
