An epitaxial wafer also known as, epi wafer, is a wafer of semiconducting material made by epitaxial growth (epitaxy) for use in photonics, microelectronics, spintronics, or photovoltaic. The epitaxial layers consist of various compounds such as gallium nitride (GaN), gallium arsenide (GaAs), or some combination of the elements gallium, indium, aluminum, nitrogen, phosphorus or arsenic. High electron mobility, low switching losses, and fewer lattice mismatches are some of the key advantages of GaN Substrate, which are leading its adoption in industries such as power electronics and optoelectronics.

Furthermore, GaN epitaxial wafers are developed by hydride vapor-phase epitaxy (HVPE) or metal organic chemical vapor phase deposition (MOCVD) method, and can be used as an ideal and excellent substrate for high frequency, high speed, and high power devices. The GaN epitaxial wafers are developed by several firms such as Aixtron, EpiGaN nv, Sciocs, and Semiconductor Wafer Inc.

Rising adoption of LEDs is leading to rising demand for GaN epitaxial wafers

GaN is widely implemented in radio frequency devices, light-emitting diodes (LEDs), and power electronics, due to its ability to operate at high frequency and high temperature. Increasing adoption of LEDs is a major factor boosting growth of the GaN epitaxial wafers market. Furthermore, advancement in GaN technology has led to the development of efficient GaN substrates with free macro defect density and low defect density. Hence, GaN substrates can increasingly be used for realizing LEDs with a wafer diameter from 2 inch up to 6 and 8 inch. Increasing adoption of LEDs is expected to drive growth of the GaN epitaxial wafers market during the forecast period. However, competition from Sic in high-voltage semiconductor applications and high product cost are factors which are expected to hinder growth of the global GaN epitaxial wafers market during the forecast period.
