100 mm single-crystal

World’s first diamond wafer

A milestone in the history of technology

100 mm single-crystal single crystal diamond wafer. World’s first diamond wafer by Diamond Foundry.
More than a diamond
An extraordinary scientific challenge
A technological breakthrough for ultimate performance

Once every few decades:

A new single-crystal wafer

Not a single ASML reticle-limit sized single-crystal diamond (SCD) existed just a few years ago. No-one knew how to make it. Now it exists and is available in volume by DF.

Unique properties
01

Direct IC wafer bondable

We achieve the ultimate thermal chip package by bonding our diamond atomically to integrated circuit (IC) wafers thinned at Angstrom precision.

02

Ultimate thermal conductor

No other material conducts heat as efficiently as single-crystal diamond, enabling chips to run faster and last longer.

Breakdown field in MV/cm: Si 0.3, SiC 3, GaN 5, Diamond 10.Breakdown field in MV/cm: Si 0.3, SiC 3, GaN 5, Diamond 10.
03

Extreme electrical insulator

The thinnest slice of diamond insulates against very high voltages, enabling the next level of miniaturization in power electronics.

Applications

Making AI Chips Bankable

We accelerate today’s most exciting mega-tech industries — each limited thermally at their technological core — by putting a diamond behind every chip.

A scientific and technological milestone

The pinnacle of decades of scientific research and development, our diamond wafer is a structure previously non-existent in the universe as well as the largest diamond on Earth.
