Sapphire Wafer Al2O3 M plane 5x5x0.5 mm Packing

The wafers are individually packaged in anti-static, moisture barrier pouches and secured within foam-lined containers to minimise mechanical damage and surface contamination. They should be stored in a temperature-controlled, low-humidity environment to prevent oxidation. The packaging includes protective films and can be customised with specific labelling and compartmentalisation upon technical consultation to meet precise storage and handling requirements.

Frequently Asked Questions

Q1: How is the M plane orientation confirmed during production?
A1: The M plane orientation is verified using X-ray diffraction and scanning electron microscopy. These methods assess crystallographic alignment and surface quality, ensuring that the substrate meets stringent processing standards.

Q2: What storage conditions are recommended for these wafers?
A2: It is advised to store the wafers in a dry, temperature-controlled environment with minimal dust exposure. The use of anti-static packaging and moisture barrier films helps prevent contamination and surface degradation.

Q3: Are customisation options available for wafer dimensions or orientation?
A3: Customisation options can be discussed based on production capabilities. Technical consultations are conducted to determine if specific modifications in dimensions or orientation can be achieved without altering the substrate’s intrinsic properties.
