概要（Overview）

The high current VIISta 80HP and VIISta 80 ion implanters feature a patented dual magnet ribbon beam architecture that currently provides the highest productivity, implant angle accuracy and 60 degree tilt angle capability—all of which are required for advanced device fabrication. Both tools have excellent process control capability for advanced ultra shallow junction applications, and can be used for source/drain, source drain extension, gate doping, pre-amorphization, and materials modification applications. Varian Semiconductor’s other high current tools include the VIISion 80 PLUS and VIISion 200 PLUS ion implanters.
