FAQ — Diamond Wafers
Single-crystal vs polycrystalline CVD diamond — which should I choose?
Single-crystal diamond (SCD) is used when low defect density and controlled crystal orientation are critical (e.g., quantum/NV and advanced devices). Poly CVD diamond is often chosen for thermal spreaders and robust engineering parts.
Can you provide custom thickness and polishing?
Yes. We can often support custom thickness and single-side or double-side polishing depending on size and grade. Share your target thickness, roughness, and flatness requirements.
What surface roughness can you provide?
Surface roughness depends on wafer type and finish (SSP vs DSP). Provide your Ra target and we will recommend a suitable finishing route.
Do you offer doped diamond wafers?
Doped diamond (e.g., boron-doped) may be available depending on size and grade. Tell us the dopant type, target concentration range, and application.
What info do you need to quote a diamond wafer?
Type (SCD vs poly), size, thickness, orientation, polishing (SSP/DSP), roughness Ra, flatness/TTV, quantity, and your application.
