Restraint Impact Analysis

Limited availability of GaN-on-SiC substrate supply and specialized fabrication facilities creates supply chain constraints for RF GaN semiconductor manufacturers

Limited availability of GaN-on-SiC substrates and foundry capacities is one of the critical constraints restraining the expansion of the RF Gallium Nitride market. The use of RF GaN devices in defense radar systems, electronic warfare, satellite communications, and advanced wireless infrastructure is based on the GaN-on-SiC platform because of their power density and thermal properties. Nevertheless, GaN-on-SiC is concentrated around just a few substrate manufacturers and qualified foundries, and the supply of these materials becomes a challenge under increasing demands from the defense and communication industries. According to SEMI, the global 300mm fab equipment investment is expected to increase by 18% to reach around $133 billion in 2026, indicating robust investment in semiconductors due to the growing need for AI and advanced electronics. But the fact is that RF GaN requires its own GaN epitaxial capability, wafer fabrication, and high-frequency testing, limiting the impact of overall semiconductor capacity expansion on GaN-on-SiC supply constraints.

Lack of access to the specialized GaN-on-SiC process capability may limit the scalability of RF GaN fabrication, prolong lead times, and become a bottleneck for the semiconductor industry. In June 2026, according to a SemiWiki article, the limitations in capacity in the GaN-on-SiC foundry ecosystem have been emphasized, causing difficulties in the supply chain for RF Gallium Nitride (GaN) semiconductor producers. The high requirement for GaN-on-SiC RF semiconductor products, which are incorporated in Transmit/Receive (T/R) modules, radar, electronic warfare, and defense communication systems, is causing limitations in foundry capacity.
