Global GaN Substrate Market Forecast 2035:
According to the report, the global GaN substrate market is likely to grow from USD 0.6 Billion in 2025 to USD 1.8 Billion in 2035 at a highest CAGR of 11.9% during the time period. Global GaN substrate market is observing high growth rates as a result of semiconductor advancement and the growing need of high-performance electronic devices. The development of technologies in the fabrication of wafer has allowed manufacturing of bigger diameter substrates with improvement of yield including 6-inch and 8-inch diameter wafers with lower manufacturing cost. As an example, in July 2025, Sumitomo Chemical announced that it had successfully developed a 6-inch GaN-on-Silicon Carbide (SiC) substrate, which will enhance the work of power electronic equipment and help to make it more affordable. The development is likely to have a high scalability effect on the devices based on GaN especially in the automobiles and industrial environment.
Moreover, the growing tendency towards electric cars (EVs) and renewable energy solutions has led to the increase in the need of high-efficiency power devices, and in this case, the use of GaN substrates is essential. Firms such as Infineon Technologies are currently working on the GaN technology in order to meet this increased demand, focusing on the efficiency and reliability of their power semiconductor products. The mentioned developments have highlighted the critical importance of GaN substrates in enhancing power electronics and facilitating the shift towards more sustainable energy systems.
“Key Driver, Restraint, and Growth Opportunity Shaping the Global GaN Substrate Market
The growing adoption of GaN substrates in high frequency radar and satellite communications systems joins the demand in the market since the systems need high levels of thermal stability and efficiency. As an example, Northup Grumman used GaN-on-SiC wafers to create superior defence radar chipsets to improve signal strength and reliability.
Minimal supply of quality and defect free GaN wafers still serves as a constraint to the growth of the market because manufacturing issues related to up-scaling of wafer size may lead to higher costs of production. Even major competitors such as Sumitomo Chemical are yielding losses in trying to use larger diameter substrates in power devices.
The new usage of GaN substrates in data center power electronics has a high potential of growth given that high efficiency and high-density power conversion are required. Efforts of Infineon Technologies in making server power supplies using GaN-on-SiC technology are just some examples of how such an application can increase markets beyond auto and RF industries.
