The global GaN Substrate and GaN Wafer market size is predicted to grow from US$ 170 million in 2025 to US$ 332 million in 2031; it is expected to grow at a CAGR of 11.8% from 2025 to 2031.

The impact of the latest U.S. tariff measures and the corresponding policy responses from countries worldwide on market competitiveness, regional economic performance, and supply chain configurations will be comprehensively evaluated in this report.

This report studies the Gallium Nitride (GaN) substrate/wafers.

Currently, the mainstream product in the industry is 2-inch GaN substrate wafers, but 4-inch GaN wafers have also been commercialized. At present, GaN substrates are mainly dominated by Japanese manufacturers such as Sumitomo Electric Device and Mitsubishi. Chinese companies are in the second echelon, with representative manufacturers including Sanan Optoelectronics, Suzhou Nanowin Science and Technology, Sino Nitride Semiconductor, Eta Research Ltd and Sino Nitride Semiconductor.

Japan is the largest market of GaN substrate/wafers, driven by demand from Photoelectric Lasers (like laser TVs). Currently, due to the high cost, the commercial application of gallium nitride substrates is still on the eve of an explosion.

In next few years, we think the GaN epitaxial wafers like (GaN on Si, GaN on SiC) will grow faster, driven by Gan power devices and GaN RF devices, especially the GaN on Si wafers, driven by demand from consumer electronics, like such as mobile phone fast charging, adapters, etc. GaN power devices have grown rapidly in recent years, and a large number of companies have gradually entered the industry. In the next few years, the main market demand for gallium nitride will come from the automotive. In the automotive, the entry point of GaN power devices is the on-board charger (OBC).
