SapphiroScope™ automated workstation inspects and assesses the quality of raw ingots (cylinders or rectangular bricks) before processing into wafer substrates for LED or into optical components.
SapphiroScope™ provides a 3D view of internal material defects without the need for polishing or ‘opening a window’. It allows the operator to sort incoming material, optimise it for the most efficient processing method, and predict wafering yield.
What it provides
- Automated mapping of bubbles, structures, and clouds prior to wafering
- Measurement and classification of defects, including XYZ position, size, morphology
- Good/bad wafers indication
- Analysis in polarised light to detect twins, lattice defects and LABs
- 3D model of defects to share with your customers and suppliers.
A 3D model visualises the defects in the sapphire cylinder or a pre-form. The user has the possibility to rotate the 3D model, scan through the core volume, zoom, visualise and measure separate defects, and indicate defective wafers.
This three-minute video demonstrates handling of a non-polished sapphire core: rotation, zoom, defect identification and wafering by an operator.
