ROHM Strengthens Supply Capability for GaN Power Devices

Core Viewpoint - ROHM Co., Ltd. is integrating its GaN power device technologies with TSMC's process technology to create an end-to-end production system, aiming to enhance supply capabilities for growing demand in AI servers and electric vehicles [1][6]. Group 1: Technology Integration - ROHM will license TSMC's GaN technology to strengthen its production capabilities [1]. - The integration represents an evolution of the existing partnership, with a new license agreement facilitating technology transfer to ROHM Hamamatsu [6]. - The production system is expected to be established by 2027 to cater to the increasing demand in applications like AI servers [6]. Group 2: Market Demand and Applications - GaN power devices are recognized for their high-voltage and high-frequency performance, improving efficiency and reducing size across various applications [2]. - The demand for GaN devices is expanding in high-voltage applications, particularly in AI server power units and electric vehicle onboard chargers [2]. - ROHM has been proactive in developing GaN power devices, having established a mass-production system for 150V GaN in March 2022 and adopted a 650V GaN process since 2023 [3]. Group 3: Strategic Partnerships - ROHM's collaboration with TSMC has deepened, particularly in the automotive sector, with a partnership established in December 2024 [3]. - Upon completion of the technology transfer, the automotive GaN partnership between ROHM and TSMC will conclude, while both companies will continue to collaborate on enhancing power supply systems [7]. Group 4: Product Branding and Adoption - ROHM's EcoGaN brand focuses on energy conservation and miniaturization by maximizing GaN characteristics [9]. - The EcoGaN series has been adopted in various consumer and industrial products, including Innergie's 45W AC adapter in 2023 and power supplies for AI servers from Murata Power Solutions in 2024 [10].
