Position detection of wafer notches

Position detection of wafer notches

The vision system detects the rotational position of wafer notches.

The resolution of the 5 Mega pixel camera and the built-in algorithms of the Trend Edge Stain tool makes it possible to stably detect the notch and also output the position and dimensional data.


A 2 Mega-pixel camera was used to detect the position of the notch, but the repeatability of the camera was not stable. By implementing the XG Series system, a 5 Mega pixel high-speed camera and the new Trend Edge Stain tool, the notch was stably located.


  • Offering a lineup of up to 21 megapixel area cameras and 8K line scan cameras, the XG Series contains powerful vision system technology providing flexibility and power to solve a wide range of applications.

  • The XG Series offers programming directly with the controller or advanced programming using the optional Vision Editor development software.

  • High Performance, Icon-driven system with easy-to-use tools for simple setup by any user.

  • The CV-5000 Series has the largest number of camera types for its class, letting you select the optimum camera for a wide range of applications.

  • Providing the ultimate flexibility with a wide variety of camera choices using the industry's highest-performance image processing engine.
