GS-300

Identifying any defect or loss on a wafer immediate is a critical part of labs and manufacturers. GS-300 helps Si wafer measurement in real-time and understanding the wafer characteristics at a glance by visualizing the results in a color-coded grid.

GS-300’s measurement system is compatible with load port, it is available as a spare unit of Φ300mm EFEM port and still adopts pattern matching and X-Y motion reproducibility of 2μm or less accuracy using RθXY stage.

 Features  
  • Compatible with the spare unit of Φ300mm EFEM port

  • Achieves pattern alignment of wiring patterns embedded in wafers

  • Responds to high throughput requirements of semiconductor process

  • Supports high precision notch alignment function
  • Minimized size allows installation in small spaces
