Magnesium Aluminate Crystal Substrate, MgAl2O4, Spinel Substrate (100) 10x10x0.5 mm SSP Packing

The substrates are individually packed in anti-static foam-lined containers to safeguard against mechanical shocks and particulate contamination. They are stored in temperature-controlled, low-humidity conditions. Additionally, cushioning padding and sealed pouches minimise exposure to environmental contaminants. Custom packaging solutions, such as vacuum-sealed options and specialised compartmentalisation, are available to meet specific handling requirements.

Frequently Asked Questions

Q1: How is the flatness of the substrate controlled during production?
A1: The substrate undergoes in-line metrology to assess surface flatness using interferometry. This process ensures that deviations remain within defined tolerances, which is crucial for subsequent thin film deposition.

Q2: What is the significance of the (100) crystallographic orientation in this substrate?
A2: The (100) orientation supports uniform lattice alignment critical for epitaxial layer growth. This alignment assists in achieving consistent electrical and optical properties in downstream semiconductor processes.

Q3: What storage measures are recommended to preserve the substrate quality?
A3: It is advised to store the substrates in a clean, temperature-controlled, and low-humidity environment using anti-static packaging. These measures guard against mechanical damage and particulate contamination that could impact substrate integrity.
