This document defines the pre-quotation material-matching and specification-confirmation checks required before using this GGG single crystal substrate. It applies to integration into a thin-film or device workflow.
- Thin-film workflow material matching: Confirm that the selected substrate material and crystal family match the target thin-film or device workflow before quotation.
- Specification option confirmation: Confirm orientation, dimensions, thickness, polishing condition, offcut details, quantity, and any custom requirements for the selected specification option.
What are the key differences between the 5×5×0.5 mm and 10×10×0.5 mm options for the GGG (110) single crystal substrate?
The only difference between the two specification options is the lateral dimensions: 5×5 mm vs 10×10 mm, both with a thickness of 0.5 mm. Both options share the same material (Gd3Ga5O12), orientation (110), surface finish (SSP), purity (99.99%), and all other physical properties. The choice is based on the required substrate area for your thin-film deposition or device fabrication.
What is the lattice constant of the GGG (110) substrate and how does it affect thin-film epitaxy?
The GGG (110) substrate has a cubic lattice constant of a = 12.380 Å. For epitaxial growth, the thin-film material should have a lattice constant close to this value to minimize strain and defects. The (110) orientation also influences the in-plane symmetry of the deposited film. Verify the lattice mismatch with your specific film composition before deposition.
What handling precautions are required for the GGG (110) single side polished substrate?
The SSP (single side polished) surface is highly sensitive to scratches, dust, and chemical contamination. Substrates should be handled with clean tweezers, stored in a cleanroom environment, and kept in the original sealed packaging until use. The 0.5 mm thickness makes the substrate brittle; avoid bending or excessive force. Cleaning should be performed with semiconductor-grade solvents prior to deposition.
This GGG single crystal substrate with (110) orientation and SSP surface finish, grown by the Czochralski method, provides 99.99% purity and a well-defined cubic lattice constant (a = 12.380 Å) for epitaxial thin-film deposition, offered in two selectable dimensions (5×5×0.5 mm and 10×10×0.5 mm, 10 pieces per box).
Positive
- High purity and crystalline quality: The substrate is 99.99% pure and grown via the Czochralski method, ensuring minimal defects and consistent lattice parameters for demanding thin-film growth processes.
- Two selectable substrate sizes: Available in 5×5×0.5 mm and 10×10×0.5 mm options, providing flexibility for different sample holder geometries or experimental requirements without changing material properties.
Trade-offs
- Material matching verification required: The substrate must be confirmed to match the target thin-film or device workflow before ordering; mis-selection of crystal family or orientation can lead to lattice mismatch and deposition failure.
- Specification review before ordering: Orientation, dimensions, thickness, polishing condition, and offcut details must be verified for each selected option, as the product is sold in fixed configurations and custom requirements may necessitate additional confirmation.
