The determination of crystal orientation is to determine the relative orientation of the invisible microscopic crystal axis and the macroscopic reference datum in the crystal, commonly known as crystal orientation. There are many applications of crystal orientation, because the crystal has anisotropic characteristics, so in the production of semiconductor devices, quartz oscillator and other crystal components must be cut in a certain direction according to the requirements. The crystal orientation instrument is used to determine the crystal orientation with high speed and accuracy.

Application of orientation instrument in crystal processing:

1. Finished crystal rod inspection:

The inspection of the finished crystal rod is an important link in the processing process, and the index must be provided for the inspection of the finished crystal rod.

2. Take more measurements.

The purpose is to check the Angle change of each point of the chip, and indirectly feedback the stress, grain boundary, crystal surface bending and other problems existing in the chip through the Angle change.

3. Face grinding

The end face grinding of the crystal rod is for the processing of the next process.
