Exclusive Interview: 'The Long-Awaited Material of Tomorrow Is Finally Moving!' IET-KY's Kao Yung-Chung: AI Elevates Compound Semiconductors to Center Stage

IET-KY is a global hidden champion in the field of compound semiconductors. Unlike traditional chips that serve as the 'brain' for computation, IET-KY specializes in 'sensory chips' that enable technology to 'see' and 'hear,' providing key epitaxial materials required for 5G/6G, AI optical communications, and defense aerospace.

The company's core strength lies in its unique 'Molecular Beam Epitaxy (MBE)' technology, which enables ultra-precise, atomic-level stacking under space-grade ultra-high vacuum conditions. With its R&D and production headquarters located in Texas, USA, IET-KY has earned the trust of the U.S. Department of Defense and top-tier military contractors, securing an indispensable strategic position in high-frequency satellite and high-speed optoelectronic links.

CEO Kao Yung-Chung stated, 'The material long hailed as the “material of tomorrow” for 30 years is finally taking center stage, thanks to AI.' As AI drives unprecedented demand for high-speed data transmission, compound semiconductors—such as gallium arsenide (GaAs) and gallium nitride (GaN)—are becoming essential for next-generation optical communication systems.

IET-KY’s MBE technology achieves exceptional crystal purity and structural control, enabling high-performance devices with extended communication range, reduced power consumption, and enhanced signal stability. These materials are critical in satellite-to-satellite links and data center interconnects, where even minor performance differences significantly impact overall system efficiency.

In defense applications, high-frequency, high-power semiconductors are vital for radar and electronic warfare systems. GaN-based devices play a central role, and IET-KY serves as a trusted supplier of high-reliability materials that support U.S. national security infrastructure.

Looking ahead, the commercialization of 6G and the expansion of low Earth orbit (LEO) satellite networks are expected to further accelerate demand for compound semiconductors. IET-KY is enhancing the scalability of its MBE processes while advancing R&D on next-generation materials to capitalize on this growth.

Operating under a cross-strait collaboration between Taiwan and the U.S., the company is strengthening its technological innovation and supply chain resilience to solidify its global leadership. As a critical but often unseen pillar of AI-era infrastructure, IET-KY’s strategic importance is poised to grow significantly.
