Core Viewpoint - The GaN market is experiencing significant changes, with TSMC announcing its exit from GaN foundry services, while other companies like Power Semiconductor Manufacturing Corporation (PSMC) and Infineon are ramping up their GaN production capabilities. This shift indicates a competitive landscape where companies are vying for dominance in the GaN semiconductor market, particularly in high-power applications like electric vehicles [1][2][3]. Group 1: TSMC's Exit and Market Dynamics - TSMC has decided to phase out its GaN semiconductor foundry business over the next two years due to declining profit margins caused by competition from Chinese manufacturers [3]. - Navitas, which previously relied on TSMC for production, will transition its manufacturing to PSMC, with plans to produce GaN products rated from 100V to 650V starting in 2026 [4]. - Infineon is increasing its investment in GaN technology, aiming to produce scalable GaN on 300mm wafers, with initial customer samples expected by Q4 2025 [5]. Group 2: Shift in Focus from SiC to GaN - Renesas Electronics has halted its SiC project and is shifting its focus to GaN, driven by a slowdown in the electric vehicle market and an oversupply of SiC chips [7]. - Renesas is leveraging its acquisition of Transphorm to enhance its GaN product offerings, introducing new high-voltage GaN FETs that improve efficiency and reduce costs [8]. Group 3: Strategic Investments and Collaborations - STMicroelectronics has extended its lock-up period for its investment in Innoscience, indicating strong confidence in the latter's future and the GaN market [10][11]. - Innoscience has emerged as a key player in the GaN market, achieving significant revenue growth and expanding its wafer production capacity [13]. Group 4: Market Growth and Challenges - The GaN semiconductor market is projected to grow significantly, with a compound annual growth rate (CAGR) of 98.5% from 2024 to 2028, potentially exceeding $6.8 billion by 2028 [14]. - However, challenges remain for GaN to transition from niche applications like fast charging to core applications in electric vehicles, which require higher reliability and ecosystem maturity [15][16]. Group 5: Competitive Landscape and Future Outlook - The GaN industry is at a critical juncture, with companies like Navitas, Infineon, and others actively working to commercialize high-power GaN solutions [17]. - The next two years will be crucial for GaN manufacturers to prove their strategies and for the market to determine if GaN can penetrate core power applications effectively [17].
