GaN，内卷加剧

Core Viewpoint - The GaN market is experiencing significant changes, with TSMC announcing its exit from GaN foundry services within two years, while other companies like Powerchip and Infineon are ramping up their GaN production capabilities. This shift indicates a competitive landscape where GaN is poised for growth, particularly in high-efficiency applications like electric vehicles and fast charging [1][4][15]. Group 1: TSMC's Exit and Market Dynamics - TSMC will gradually phase out its GaN semiconductor foundry business due to profit margin pressures from Chinese competitors, halting the development of 200mm wafer production [1][2]. - Navitas Semiconductor plans to transition its production from TSMC to Powerchip, with expectations to produce GaN products rated from 100V to 650V by mid-2026 [2]. - The exit of TSMC opens opportunities for other players like Powerchip and Infineon to fill the production gap and capture market share [1][4]. Group 2: Competitor Strategies - Infineon is advancing its 12-inch GaN production, with plans to release customer samples by Q4 2025, leveraging its IDM model for scalable production [4]. - Renesas Electronics has shifted focus from SiC to GaN, suspending its SiC projects due to market saturation and is preparing to enhance its GaN capabilities following its acquisition of Transphorm [5][6]. - ROHM is committed to deepening its collaboration with TSMC to address market demands and explore future production frameworks [3]. Group 3: 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 [15]. - The main drivers for GaN market growth include consumer electronics and electric vehicles, with expectations for GaN applications in fast chargers and adapters to grow at a CAGR of 71.1% [15]. - Transitioning GaN from peripheral applications to core power systems in electric vehicles presents challenges, including reliability and ecosystem maturity [16][17]. Group 4: Strategic Partnerships and Investments - STMicroelectronics has extended its lock-up period for its investment in Innoscience, signaling confidence in the latter's future and the broader GaN market [9][11]. - The partnership between ST and Innoscience aims to leverage each other's manufacturing capabilities to enhance GaN product development and production [12]. - Innoscience has emerged as a key player in the GaN market, achieving significant revenue growth and expanding its wafer production capacity [14].
