Gallium Arsenide (GaAs) Wafer Market: Growth Drivers

Rising semiconductor sector drives market growth

The semiconductor industry has expanded quickly in response to the growing demand for electronics across a spectrum of uses, including smartphones, tablets, personal computers, cars, industrial, and other electronic devices.

For instance, the Semiconductor Association estimates that by 2025, the semiconductor market overall would reach a staggering $20 trillion. In power electronics, several semiconductors are used, such as gallium nitride (GaN), silicon (Si), and silicon carbide (SiC). SiC and GaN are sometimes too expensive and cannot be used for larger currents; silicon performs poorly in higher energy density and temperature situations.

Because of its flexibility for high temperature and frequency, gallium arsenide (GaAs) is often used in microelectronics, but not for electrical conversion and control.

Microelectronics also make frequent use of gallium arsenide because it may be used at high temperatures and frequencies to fulfill specific performance criteria. Gallium arsenide has grown to be a strong candidate for ultrahigh-speed applications in the next generation of communication devices and supercomputers due to its exceptional performance in ultra-high frequency uses. Therefore, the growing semiconductor sector drives market expansion.

Gallium Arsenide (GaAs) Wafer Market: Restraints

The high product cost of GaAs hinders market growth

Silicon has typically served as the foundation for computer chips, solar cells, and the majority of electrical gadgets. As with faucets that regulate water flow, electricity may be turned on and off by manipulating the unique electrical characteristics of silicon.

Among these semiconductor materials, GaAs has some technical benefits over silicon. For instance, electrons move more quickly through its crystalline structure than they can through silicon.

However, the primary factor influencing the continued preference for silicon in the majority of electronic devices is the significantly higher cost of GaAs devices compared to silicon. Only specialized applications where the unique features of GaAs-based devices justify their higher cost are utilized.

Although GaAs wafers are utilized in solar cells, which are used in some high-end applications like satellites, their price is very high since they are made to have a higher photon-to-electricity conversion efficiency. GaAs wafers are therefore not widely used in general electrical devices because of their high production costs, which further limits the expansion of the targeted market.

Gallium Arsenide (GaAs) Wafer Market: Opportunities

Growing partnerships offer a lucrative opportunity for market growth

The growing partnership is expected to offer a lucrative opportunity for the Gallium Arsenide (GaAs) Wafer industry to expand over the projected period.

For instance, in April 2024, with a multi-year supply arrangement, IQE plc, the top global supplier of compound semiconductor wafer products and innovative material solutions, announced the extension of its collaboration with the innovative Wireless Semiconductor Company ("AWSC").

To create smartphone power amplifier devices for its major client, Lansus, the Chinese RF technology supplier, IQE will provide AWSC with Gallium Arsenide ("GaAs") wafers as part of their strategic relationship.

In the Android ecosystem, this will serve Tier One China-based OEMs in a market that is anticipated to rise again after a period of inventory accumulation.

Gallium Arsenide (GaAs) Wafer Market: Challenges

Competition from alternatives poses a major challenge to market expansion

Gallium arsenide (GaAs) wafers have higher electrical and optoelectronic properties, but in many uses, silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) are strong rivals. Silicon wafers are far less expensive because of their mass production and ample raw material availability.

Furthermore, whereas Si wafers can reach widths of up to 300mm (12 inches), GaAs wafers typically range from 2 to 6 inches, therefore restricting GaAs scalability.

In addition, they outperform in high-frequency applications (mmWave, radar, and 5G base stations) compared to GaN. Thus, this poses a major challenge for the expansion of the Gallium Arsenide (GaAs) Wafer industry.
