Coherent’s AM technology for advanced ceramic components

Coherent has developed an additive manufacturing process capable of producing advanced ceramic components for high-performance thermal management applications, including for next-generation semiconductor capital equipment.

Severe shortages of integrated circuits based on leading-edge nodes have spurred massive investments worldwide in the buildout of semiconductor manufacturing facilities equipped with the most advanced semiconductor capital equipment. Coherent has successfully developed proprietary materials and technologies that enable ceramic components produced with its additive manufacturing process to match those produced with its existing moulding process in their mechanical and thermal properties. Ceramic components manufactured with the new additive manufacturing process can now be precision-machined using the most advanced laser-based techniques, including those available at Coherent. These are critical for next-generation semiconductor capital equipment. Additive manufacturing is superior to moulding in process capability, yield, and throughput. It requires no retooling time between components, which minimises lead times and waste. As such, additive manufacturing is ideal for Industry 4.0 factories that are designed for resilient and flexible scaling.

“Ceramic additive manufacturing enables components that are lighter and with entirely new geometries, which are required for next-generation semiconductor capital equipment designs. Until now, these components were lower in quality and precision compared with moulded ceramic components. With this new breakthrough, our customers will benefit from the best of both worlds,” said Steve Rummel, Senior VP, Engineered Materials and Laser Optics Business Unit. “We’re moving quickly to establish a new ceramic additive manufacturing line in Temecula, California. We’ve also defined with our customers a strategic roadmap to broaden our additive manufacturing capabilities, beyond ceramics, to a wider range of materials, including metals.”

Ceramic components produced with the proprietary additive manufacturing process from Coherent can achieve a state-of-the-art elastic modulus of 365 GPa and a flexural strength of 290 MPa. They are ideal for a wide range of semiconductor equipment, including in photolithography, deposition, and etching. They are also a great solution for advanced packaging components with integrated cooling channels, for high-performance computer processors such as CPUs and GPUs.
