Samsung’s First 8-Inch GaN Wafer Production Line Expected to Begin Mass Production as Early as the Second Quarter

According to a report by South Korean media outlet The Elec, Samsung’s first 8-inch gallium nitride (GaN) wafer production line is expected to enter mass production as early as the second quarter of 2026, with initial revenue projected to remain below 100 billion won.

The report notes that Samsung has established a comprehensive GaN solution ecosystem covering everything except chip design and possesses the capability to independently produce GaN epitaxial wafers.

Additionally, Samsung plans to launch operations for its silicon carbide (SiC) power semiconductor foundry line within this year. The company possesses end-to-end capabilities in the SiC segment, including design, which can complement GaN technology across different voltage ranges.

Previous reports also revealed that Samsung has invested approximately 100 to 200 billion won in advanced process equipment, including Aixtron’s MOCVD systems, to support the processing of silicon-gallium and gallium nitride wafers.
