The sale of nearly 600 crates of equipment from brands like Aixtron and KLA suggests a consolidation in the high-efficiency PV space, as firms seek to optimize their GaAs thin-film production capabilities or exit the niche in favor of other materials.
Competition and Synergy with GaN and SiC
The compound semiconductor landscape is broadening. Onsemi’s December 2024 acquisition of Qorvo’s SiC JFET business (United Silicon Carbide) for $115 million illustrates the intense activity in the power semiconductor space. Furthermore, the development of 8-inch GaN processes in Taiwan (February 2025) challenges GaAs in certain high-frequency applications. However, the market currently views these materials as complementary: GaAs for high-volume mobile RF and low-power sensing, and GaN/SiC for high-power infrastructure and electric vehicles.
The Ultra-Wide Bandgap (UWBG) Frontier
