It has taken 25 years to get here and 300mm diamond wafers are in its sights for 2030.

Watch On What makes Diamond Foundry’s 200mm SCD wafer different from other lab-grown diamonds is that it’s created as a high-quality single-crystal piece instead of a polycrystalline gem. Although the former is difficult to manufacture, it is what allows diamond to become an extreme efficient thermal conductor while simultaneously retaining its electrical insulating properties — this efficiency should help cut down on hotspots, making SCDs an excellent solution for AI chip cooling.
The company also showed in a graph that it is now thought possible to create a D300 SCD wafer before 2030, matching the size of the wafers used in leading node processes. However, it should be noted that the sample shown by the company remains unpolished, meaning it still needs to go through some processes to make it suitable for chipmakers.
Although the company was founded in 2012, it also acknowledged the work of scientists who have been chipping away at the scale problem of SCDs since the early 2000s. “This is one of those milestones that once seemed almost impossible. Hundreds of DF engineers, scientists, and technicians contributed to us getting here. It is the accumulated result of countless experiments, failures, inventions, rebuilt machines, and insights over more than a decade,” Diamond Foundry CEO Martin Roscheisen said.
“Stefan and Martin pursued this goal for 25 years. There are very few examples in technology of someone sticking to a really hard scientific challenge with that level of perseverance. They kept going when the prevailing view was that single‑crystal diamond simply could not be made at this scale. Today, the perseverance shows as the first-ever D200mm single‑crystal diamond. And best of all, it makes D300mm predictable as well.”
