H116SPN Wafer Shuttle Stage
Description
|
|
The Prior Scientific motorized Shuttle Stage is designed to be used with the Nikon and Olympus wafer loader systems for 3, 4, 6, and 8 inch wafers. The system greatly reduces operator fatigue while increasing inspection accuracy and repeatability. In operation, the Shuttle System automatically moves to the correct load position and activates the loader switch, notifying the loader that the shuttle's wafer chuck is in position to receive the wafer. After the wafer is transferred to the shuttle, the system senses the vacuum change and retracts the shuttle, moving the wafer to a pre-defined position (home). From this point the wafer can be scanned using the joystick or a programmed pattern for totally automated inspection. The Shuttle Stage is used in conjunction with Prior's touchscreen keypad. This keypad allows users to quickly and easily set up and store inspection patterns and other stage parameters. |
