FSAS III

Automated crystalline orientation measurement system 

For SiC, graphite, GaN, Si, Ge, GaAs, LN, LT, sapphire, etc.

From production to quality control of single crystal materials, X-ray diffraction systems for single crystal orientation and quality assurance.

FSAS III Overview

After measuring the orientation of various single crystal materials such as Si, Ge, GaAs, SiC, quartz, LN, LT, sapphire, rutile and fluorite accurately, the FSAS III transmits the angle cutting information to the cutter (for instance, to a wire saw). The orientation verification measurement of single crystals after cutting can also be carried out automatically. No special skills are required by the operator. 

FSAS III Features

Even a novice can handle automatic determination of the cutting orientation of various single crystal materials. (Note: Depending on the sample shape, cutting method and cutter type, there may be a need to make a custom sample holder.)
Once the measuring conditions are stored in the FSAS III using a touch panel interface, the operator only has to click “Measurement Start” to conduct the automatic measurement. The measurement result will then be displayed on the screen while a hard copy is being generated.
The cut angle of a block or wafer sample can be automatically verified after cutting.
X-ray measurement and optical system alignment are automated to ensure reliable measurements
Special design consideration is given to safety, so the sample insertion door will be locked instantly at the start of a measurement. Access to the sample is provided at the end of the measurement.
The FSAS III is designed so that generated X-ray are fully confined to the system interior.
