Gallium Arsenide Wafer Market Size

The global gallium arsenide wafer market size was valued at USD 1.14 billion in 2024 and is estimated to grow at CAGR of 11.8% from 2025 to 2034, driven by the expansion of 5g and high-frequency wireless infrastructure and advancements in optoelectronics and photonics.
 

The international 5G network rollout is a primary driver for the GaAs wafer industry. The fabrication of RF components like power and low noise amplifiers, which are necessary to transmit signals in 5G infrastructure, requires GaAs wafers. Unlike silicon, GaAs boasts of much higher electron mobility and saturation velocity; thus, devices can operate efficiently at the high frequencies needed for 5G technology. GaAs semiconductors are ideal for applications requiring intensive dataflows and minimal delays.
 

The Asia-Pacific region showcases this trend, including China and South Korea as parts of this region that actively support the expansion of 5G Technology. For example, India plans to increase its spending towards the 5G network overhaul to over 125 billion USD by 2025, making the demand for GaAs wafers soar in this region. The spending is greatly improving the telecommunication systems and augments the demand for advanced RF components, which fuels the gallium arsenide wafer market.
 

The region of North America is also increasingly accepting 5G technology. By September 2023, the penetration figure for 5G reached 40%. It is estimated that the number of 5G connections will hit 669 million by 2028. The swift growth puts into context the importance of GaAs wafers in the provision of the facilities needed for the next-generation wireless communication systems.
 

The optoelectronics industry relies heavily on GaAs wafers for the fabrication of LEDs, laser diodes, and photodetectors. These devices utilize the material's properties, such as light emission and detection, due to its direct bandgap and high electron mobility. Demand for GaAs components is expected to increase with more advanced sensing technology, energy-efficient lighting, and high-resolution displays.
 

An example of note is QE RGB’s 200mm microLED epitaxial wafer product launch for microLED display qualification in May 2023. MicroLED technology is significantly more energy efficient and brighter than conventional displays, which widens the scope of GaAs wafers needed for the construction of red-light-emitting diodes. This is a great advancement for GaAs in the upcoming display technology market.
 

GaAs solar cells are an important product of space exploration, having powered NASA’s Mars Exploration Rovers Spirit and Opportunity for years. This highlights the importance of GaAs wafers and adds to their versatility by demonstrating the reliability and efficiency of optoelectronic technologies across various industries.
