Historical diamond wafers were limited to small sizes — useless for modern AI packaging. Our advanced CVD technology changes everything.
Standard rectangular plates ship today. Larger wafer-scale formats are available under qualification for selected partners.
Single-crystal diamond delivers the highest thermal conductivity of any material — spreading hotspots evenly across entire substrates.
An epi-ready surface option enables atomic-level direct bonding for GaN-on-Diamond and other advanced heterostructures.
Sign in to see the standard geometries, surface-finish options, and thickness ranges for our SCD wafer line. Custom DFM is available for any footprint.
Our SCD wafers enable wafer-level packaging, GaN-on-Diamond integration, and extreme-power testing.
2.5D/3D Advanced Packaging for AI accelerators
Contiguous SCD plates spread extreme localized heat (hotspots) from the GPU die evenly across the substrate, preventing thermal throttling and protecting adjacent HBM stacks.
GaN-on-Diamond or Silicon-on-Diamond
The epi-ready surface option allows atomic-level direct bonding for massive arrays of RF or power chips with integrated diamond heat sinks.
Wafer-level testing of 1000W+ HPC chips
Prevents unpackaged semiconductor chips from self-destructing due to overheating during high-current fab testing, dramatically increasing yield rates.
Gallium Nitride (GaN) on Diamond substrates are ideal for CPO laser driver ICs. GaN provides high electron mobility for high-frequency operation, while diamond provides extreme thermal conductivity to handle the heat load from dense laser arrays.
The standard form factor enables standard fab processing for GaN-on-Diamond heteroepitaxy, making it viable for high-volume CPO optical engine production.
