Wafer Orientation Instrument Working Principle

The device operates through ​​X-ray diffraction​​ and ​​Omega scanning​​ technologies:


​​1. X-ray Diffraction​​:

  • X-rays incident on the crystal surface at Bragg angles generate diffraction signals, enabling calculation of lattice spacing and orientation.
  • Rocking curve scanning evaluates lattice defects and surface strain.

​​


2. Omega Scanning​​:

  • The crystal rotates around a fixed axis while X-ray tube and detector remain stationary, dynamically collecting multi-angle diffraction data for full lattice mapping in 5 seconds.
  • Integrated X/Y/Z-axis motion enables 3D crystallographic orientation.

​​

3. Automated Control​​:

  • PLC or computer-controlled sample rotation and data acquisition, supporting preset cutting parameters (e.g., 8° or 32° cuts for silicon wafers).
