Exclusive: Gallium oxide prepares to tackle power semiconductor market with 6-inch mass production and 8-inch breakthroughs

Gallium oxide (Ga 2 O 3 ) is approaching a pivotal industrial inflection point. On one hand, wafer sizes are scaling up to seamlessly integrate with existing semiconductor manufacturing lines. On the other hand, material prices are expected to decline substantially starting in 2027. The convergence of these two trends is unlocking commercial viability for this new high-voltage power material, which targets ultra-high-voltage applications above 3,000V and grid infrastructure in the 10kV class.
