Now exists: The ultimate AI chip substrate
Single crystal diamond (SCD)
Hotspots limit chip speed & lifetime.
At the root of a plethora of AI chip failure mechanisms: Hotspots are Evil.
Now exists and available at scale: Chip scale SCD — resulting in: Hotspots, Gone.
By giving them their max thermal envelope for max lifetime token, we help Make AI Chips Bankable.
Milestones in the history of technology.
World’s first D100, D200 single-crystal diamond
Applications
SCD Substrated Chips
Single-crystal diamond (SCD) substrated chips enable bankable AI chips, advanced cooling, and next-gen 3D packaging.
DF Technology
We have not just designed, developed, and built an entirely new semiconductor-grade tech stack; we also operate it at scale and as green as it gets, including a "real zero" carbon footprint.
