Korea's Next-Generation Gallium Oxide Power Semiconductor Technology Presented on the International Stage

The Korea Institute for Advancement of Technology (KEIT) announced on the 28th that it presented the achievements of the "Development of High-Efficiency, High-Reliability Gallium Oxide Power Semiconductor Device Technology," developed through the materials and components technology development project, at the International Gallium Oxide Workshop (IWGO) held in Berlin, Germany, from the 26th to the 31st.

Gallium oxide (Ga2O3) is a next-generation device that can operate at higher temperatures, voltages, and frequencies due to the large difference between its conduction band and valence band. It is establishing itself as the third-generation power semiconductor following silicon carbide (SiC) and gallium nitride (GaN). IWGO is the world's premier gallium oxide academic workshop where semiconductor experts from around the globe gather to share the latest technologies and research results.

The lead research and development organization, the Korea Semiconductor Research Consortium, participated in this event to showcase the domestic gallium oxide power semiconductor materials ecosystem, including gallium oxide powder, substrates (wafers), and power device module finished products. The Semiconductor Research Consortium exhibited and demonstrated gallium oxide raw powder materials and commercialization-level gallium oxide diodes (SBD, Schottky Barrier Diode). KEIT explained, "The high-quality single crystal growth technology is a technique that manufactures processed substrates from single crystal ingots grown by the melting method. Compared to existing wide bandgap materials, it enables high quality, large diameter, and cost reduction, and is expected to attract significant attention as a next-generation material."

Meanwhile, the Ministry of Trade, Industry and Energy and KEIT have been supporting the project "Development of High-Efficiency, High-Reliability Gallium Oxide Power Semiconductor Device Technology" from April 2021 to December 2024. This project involves PowerCubeSemi and the Korea Ceramic Technology Institute as participants.
