The Extrion 1000: A new high current ion implantation system for automated fabrication environments and intelligent process control
The next generation of ion implantation systems will require new techniques for intelligent process control while satisfying the increasing need for high reliability and serviceability. The Extrion 1000, a new Varian batch process ion implantation system designed to address these needs, is described. The new implanter features extensive real time process monitoring capability, failure prediction technology, wide dynamic range, and rapid changeover between processes requiring different implant angles or wafer sizes. Adaptive control techniques are used within the framework of an automated fabrication environment to assure high yield and throughput.
