Samsung Electronics is reportedly preparing to launch mass production at its 8-inch Gallium Nitride (GaN) power semiconductor foundry in the second quarter of 2026.
This move, though about a year behind its initial 2023 roadmap, appears to be a calculated response to a confluence of powerful market forces. So, why now? The reasons can be broken down into three main factors.
First, the explosive growth in power consumption by AI data centers is the core driver. As AI models become more complex, they demand massive amounts of electricity. To manage this efficiently, the industry, led by companies like NVIDIA, is shifting to an 800V high-voltage direct current (HVDC) architecture. This is where GaN semiconductors shine. They are far more efficient than traditional silicon in converting high-voltage power to the lower voltages needed by server components, reducing energy loss and heat.
Second, a unique market opportunity has opened up. TSMC, the world's leading foundry, announced its decision to exit the GaN foundry business by 2027. This departure creates a significant supply vacuum, leaving many fabless chip designers searching for a new manufacturing partner. Samsung, with its established foundry capabilities, is perfectly positioned to capture this displaced demand and establish a strong foothold in the growing market.
Third, favorable market conditions and domestic pressure have also spurred Samsung into action. The global capacity for 8-inch wafers, used for GaN chips, is tight, which supports pricing and improves the profitability of new foundry services. At the same time, domestic competitors like DB HiTek and SK keyfoundry are aggressively developing their own GaN processes. This creates a sense of urgency for Samsung to solidify its leadership before the domestic market becomes more crowded.
In conclusion, Samsung's decision to launch its GaN foundry service, while seemingly delayed, is a strategic move to secure a future growth engine. It's less about short-term stock performance and more about positioning itself at the heart of the power infrastructure for the AI era.
