Munich-based semiconductor startup Quantum Diamonds has secured €91 million in new funding to bring its diamond-based technology to mass production.

The capital injection marks a significant step for the 2022-founded company, which aims to commercialize a novel approach to chip manufacturing that could offer superior thermal and electrical properties compared to traditional silicon.

The European Commission previously approved €76 million in German state aid for the company, designated for the construction of a new production facility in Munich.

The fresh financing complements earlier support from public sources.
