台积电改写GaN格局

Core Viewpoint - TSMC's decision to exit the GaN foundry service by July 2027 is reshaping the GaN industry landscape, transitioning from reliance on advanced foundries to a focus on specialty process foundries [2][19]. Group 1: TSMC's Exit and Industry Impact - TSMC has been a crucial player in the GaN industry, being the only foundry capable of providing both high and low voltage GaN solutions [2]. - The exit of TSMC is prompting second-tier foundries to accelerate their capacity to fill the void left behind, leading to a reconfiguration of GaN manufacturing capabilities [2][5]. - GlobalFoundries (GF) has signed a GaN technology licensing agreement with TSMC, aiming to establish itself as a strategic GaN production center in the U.S. with over $80 million in federal funding [3]. Group 2: New Entrants and Strategic Moves - World Advanced (VIS), a TSMC subsidiary, is also entering the GaN market by expanding its GaN-on-Si capabilities, targeting mid-to-low margin orders previously handled by TSMC [3]. - Navitas, a major GaN customer of TSMC, is diversifying its supply chain by partnering with PSMC for 200mm GaN-on-Si production and strengthening ties with GF to mitigate manufacturing risks [4]. - ROHM is shifting from relying on TSMC to producing GaN devices in-house, establishing a new 8-inch wafer production line in Japan [7]. Group 3: Market Dynamics and Growth Projections - The GaN market is expected to grow significantly, with projections indicating a market size of approximately $3 billion by 2030 and a compound annual growth rate (CAGR) of 42% from 2024 to 2030 [10]. - The demand for GaN is expanding beyond consumer applications into high-reliability sectors such as data centers and electric vehicles, with automotive applications projected to grow at a CAGR of 73% from 2024 to 2030 [13]. - The shift in GaN applications is moving from consumer electronics to critical systems in data centers and automotive power supplies, emphasizing the need for reliability and efficiency [19]. Group 4: Structural Changes in the GaN Industry - The exit of TSMC is not a sign of declining GaN demand but rather a transition towards a decentralized manufacturing model, where multiple foundries share the production load [19]. - The industry is witnessing a redistribution of power, with IDM manufacturers regaining control over core processes and Fabless companies gaining more flexible manufacturing options [19]. - The GaN industry is evolving into a more independent and scalable sector, moving away from dependence on a single advanced foundry [19].
