World-leading GaN-on-Si and
GaN-on-SiC epi wafers

Validating the epitaxy manufacturing service business model for RF and power devices – Interview with EpiGaN by Yole Developements

Devices using GaN-on-silicon and GaN-on-SiC technologies are gaining traction in real products, improving performance and simplifying systems, both for radio-frequency (RF) applications and power devices. However, Toshiba has stopped manufacturing GaN-on-silicon LEDs, almost eliminating interest in such devices. Yet, in 2016, Yole Développement (Yole) is expecting the GaN-on-silicon and GaN-on-SiC market to reach $20M for power devices and multiple hundreds of millions of dollars for RF devices. According its GaN and SiC Devices for Power Electronics Applications report, Yole expects a compound annual growth rate close to 40% over the next five years, due to strong adoption of GaN devices in power systems.

It’s particularly interesting that integrated device manufacturers (IDMs), fabless companies and foundries are all entering the GaN market and developing dedicated technologies. Establishing this supply chain is quite challenging and needs specific expertise in GaN epitaxy. Several companies are providing such services, including EpiGaN in Belgium. Yole has interviewed Dr Marianne Germain, EpiGaN’s CEO and co-founder, about the company's expected evolution and the market developments it foresees.

Yole Développement: What does EpiGaN do?
Marianne Germain: EpiGaN manufactures GaN-on-silicon and GaN-on-SiC epitaxial wafer materials and supplies these to integrated device manufacturers to create high-performance power and RF devices. The company was created in 2010 as a start-up from the research and development activities of IMEC. In the last five years the company has developed and implemented a production facility to support volume production of epiwafers, including a wafer characterisation lab [...]

YD: How does EpiGaN see the GaN-on-silicon/GaN-on-SiC market? What are the main applications that are driving the market?
MG: RF devices using GaN-on-silicon and GaN-on-SiC are becoming increasingly mature, with volume production being put in place and significant market traction [...]
