Forget silicon. Diamond may be the next semiconductor material - Chemical & Engineering News

As emerging technologies such as artificial intelligence, electric vehicles, and quantum computing push the limits of traditional silicon-based semiconductors, diamond is emerging as a promising next-... Read original →

Diamond semiconductors will trigger a full-stack reconfiguration—from substrate fabrication to quantum chip design. If MPCVD achieves 8-inch wafer scale, it will directly erode SiC and GaN’s dominance in high-voltage power devices and force EUV lithography toward shorter wavelengths to handle diamond’s extreme refractive index. New export controls on wide-bandgap materials from the U.S., Japan, and EU are imminent, exposing firms like Diamfab to equipment embargoes and IP encirclement, potentially inflating localized supply chain costs by over 30%. TSMC and other Taiwan, China foundries won’t abandon silicon-based 3nm lines soon but may invest in PolarisQB to develop hybrid quantum-sensing interfaces. Within 18 months, if Diamond Foundry cuts single-crystal diamond wafer costs below $5,000 per piece, industrial adoption will surge first in aerospace electronics and AI data-center power modules—marking the true onset of the post-Moore materials revolution.
