Coherent Corp. has announced a significant advancement in its next-generation 300mm silicon carbide (SiC) platform, addressing the growing need for enhanced thermal efficiency in AI datacenter infrastructure.
Building on its established expertise in 200mm SiC technology, Coherent has developed a 300mm solution designed to support the increasing power density and heat dissipation requirements of next-generation datacenters. This development marks a key milestone in the industry’s shift toward larger-diameter SiC substrates, offering improved scalability, faster switching performance, and superior thermal management for high-performance computing environments.
The new platform delivers conductive SiC substrates characterized by low resistivity, low defect density, and high material homogeneity—features that are critical for achieving high-frequency operation, low energy dissipation, and thermal stability in demanding AI and data infrastructure applications.
“AI is transforming the thermal-management landscape in datacenters, and silicon carbide is emerging as one of the foundational materials enabling this scalability,” said Gary Ruland, Senior Vice President and General Manager at Coherent. “Our 300mm platform, which we plan to ramp in high volumes, delivers new levels of thermal efficiency that translate directly into faster, more power-efficient AI datacenters.”
In addition to datacenter applications, Coherent is expanding the use of its SiC technology in augmented and virtual reality (AR/VR) devices and power electronics. For AR smart glasses and VR headsets, the 300mm SiC substrates support thinner, more efficient waveguides, enhancing performance and reliability in compact optical modules. In power electronics, the larger wafer size enables higher device yields and lower cost per chip, supporting a range of applications including electric vehicles, renewable energy systems, and industrial automation.
The introduction of the 300mm SiC platform solidifies Coherent’s leadership in wide-bandgap semiconductor materials and underscores its commitment to enabling innovation across datacenter infrastructure, optics, and power electronics.
