Global GaN on Silicon Templates Market Strategic Research Report

Scope of the Report

The global GaN on Silicon Templates market size is predicted to grow from US$ 354 million in 2025 to US$ 1,480 million in 2032; it is expected to grow at a CAGR of 23.1% from 2026 to 2032.

Gallium nitride (GaN) is used as the wide band gap material for next generation power semiconductors and high frequency devices.

Gallium Nitride on Silicon wafers are used for both Power and 5F/RF application, D-mode GaN-on-Si HEMT & E-mode GaN-on-Si HEMT, etc.

Currently the key size is 6 inch GaN Si wafer, and the 8 inch GaN Si wafer will grow faster.

Growing new applications like data centers, renewables and the next generation of wireless networks (5G) need high switching frequencies and efficient energy management, while working under high power densities. GaN technology enables all three properties. By doing so, GaN technology not only supports future growth markets, but helps contributing in parallel to decarbonise digitalisation, energy distribution and mobility. Hence GaN-on-Si wafers are expected to be increasingly used as material of choice for such applications.

The global key manufacturers of GaN-on-Si Wafer include Innoscience, NTT Advanced Technology (NTT-AT), DOWA Electronics Materials, Enkris Semiconductor Inc, IQE, Soitec (EpiGaN), China Resources Microelectronics Limited and Sumitomo Electric Device Innovations (SEDI) (SCIOCS), etc. In 2023, the global top six players had a share approximately 75% in terms of revenue.

In terms of product, currently the 6 inch GaN-on-Si Wafers is the largest segment, hold a share about 66%. In next ten years, 8 and 12 6 inch GaN-on-Si Wafers will grow faster.

Currently the Consumer Electronics is the largest application, with a share about 85%, in next ten years, this segment will still be the largest market. Automotive electronics will be fastest growing application, especially in OBC, DC/DC, and radar/ self-driving.

In past several years, more and more Chinese players are entering the GaN market, it is projected that, China will play more roles in next ten years.
