Silicon Wafer Contamination Characterization

Tordivel Solar has developed a revolutionary optical inspection system for Wafer Cosmetic Effects.

Read more in the press release.

The Wafer Surface Inspection System is performing an automatic surface quality control on wafers targeting the solar cell industry.

Multiple Failure Modes

Based on experience and with a standard configuration, the following failure modes are defined in the system:
  • large area contamination,
  • small area contamination
  • lines and spots
  • dark spots
  • suction cup marks
  • shiny patches.
The system works both for mono and poly-crystalline wafer.

Scorpion 3D Training – August 10-12, 2010 in India

We are pleased to announce that we arrange a Scorpion 3D training in India.

Fly in to the best machine vision training and learn from the experts behind Scorpion Vision Software®. The course
is based on the new Scorpion Vision Software® release 8.1 including Stereo Vision and 3D Robot Vision.
The course starts with a Scorpion basic introduction, continues with advanced 2D vision tasks and brings you further through 3D vision solutions.
  • August 10-12, 2010, 3 days Scorpion 2D and 3D Training Course, Pune, India, Invitation

Advanced 3D Tutorial – Creating 3D Point Clouds using Laser Triangulation

We are please to announce a new tutorial showing how to create high accuracy 3D images in Scorpion using laser triangulation.



Scorpion Laser Triangulation

  • Advanced Training – Creating a 3D Image with Scorpion Laser Triangulation – 30 Mbyte
  • More information about getting started with Scorpion on Scorpion Vision Online.

    Read more about the actual hw and sw setup. The concept can be extended to use the high performance Sick 3D sensors and two measure an object two or three-sided to aquire for instance thickness profile of a knife.

    Getting Started with a live Camera locating objects

    A brand new Getting started tutorial is available :)

    This will be our first detection system configured using flexible and feature-rich Scorpion, which process live video and does real-life detection. Scorpion is very user friendly and simple to use. This makes it possible even for the first time users to quickly configure a real-life detection system working on live video; without needing any extensive training and without needing any programming!
    In this tutorial, we will install the web-camera on the test machine and confirm whether it is installed properly. Then we will access the live video from Scorpion and configure it for object detection. The system will generate ‘Pass’ result when at least one object is detected in the captured image, and it will generate ‘Fail’ result when no object is detected in the captured image.
    However, before starting to work on live video captured from the camera, we will see the system working in ‘simulation mode’. Scorpion also provides the important feature where as image files saved on the computer hard-disk can be used to simulate the video from camera. This feature is useful in set up and also during analysis and optimization phases, since these can also be done off-line and on remote computers, without needing the full inspection hard-ware set up.
    In this tutorial, we will be using the camera simulation mode to understand the working on the final detection system. A pre-configured profile ‘Connecting_Camera.zip‘ available with this tutorial, will be used for the same.
    Scorpion Vision Software supports all IIDC compliant firewire cameras through Unibrains generic drivers. It also supports advanced features like hardware triggering, non continuous video streams, dynamic shutter, direct register access, raw colour format and mode-7 etc.
    Firewire cameras from following vendors are supported – ADS, Allied Vision, Basler Vision, Baumer Optronics, Hamamatsu, Imaging Source, JVC, MicroPix, OrangeMicro, PixeLink, PointGrey, Sony, Teli, Unibrain, Victor.
    Scorpion Vision Software is very flexible and it also supports cameras which expose Microsoft DirectShow interface.
    This includes the normal web-cameras connected to the computer through USB port. These cameras are general purpose and easily available. Scorpion supports both high end cameras as well as general purpose cameras. In this tutorial, we will use the general purpose web-camera connected to the computer and will configure Scorpion to capture images from this connected camera and also detect objects in the captured image.

    All tutorials are listed at Scorpion Online.
