Apple Is Changing GaAs Future

 
After finding success in the GaAs RF market, GaAs photonics is now a rising star, says Yole

After a quiet period due to the saturation of the mobile handset industry, the GaAs wafer market is waking up, according to a new resport by Yole Développement (GaAs Wafer and Epiwafer Market: RF, Photonics, LED and PV Applications report, July 2018). It forecasts a 15 percent CAGR between 2017 and 2023 (in volume), with an impressive 37 percent, especially for photonics applications.

As one of the most mature compound semiconductors, GaAs has been ubiquitous as the building block of power amplifiers in every mobile handset. In 2018, GaAs RF business represents more than 50 percent of the GaAs wafer market. However, market growth has slowed down in the past couple years due to the handset market’s gradual saturation and shrinking die size.

“At Yole, we expect GaAs to remain the mainstream technology for sub-6 GHz instead of CMOS, owing to GaAs’ high power and linearity performance as required by carrier aggregation and MIMO technology," explains Dr. Hong Ling, Technology and Market Analyst at Yole.

Since 2017, GaAs wafer has been particularly notable in photonics applications. When Apple introduced its new iPhone X with a 3D sensing function using GaAs-based lasers, it paved the way for a significant boost in the GaAs photonics market. GaAs wafers market segment for photonics applications should reach $150 million by 2023.

“GaAs-based ROY and infrared LED applications have also caught our attention", asserts Ezgi Dogmus, technology and market analyst at Yole. “We estimate, 2017-2023 CAGR achieves 21 percent (in units) for the total GaAs LED market, surpassing more than half of GaAs wafer volume by 2023."

In terms of the wafer and epiwafer businesses, each application requires a different size and quality when determining wafer and epiwafer prices. As a new entrant, photonics applications will impose new specification requirements compared to the well-established RF and LED wafer and epiwafers, creating significant ASP diversity.

From a value chain point of view, the GaAs photonics market’s remarkable growth potential will offer plenty of opportunities for wafer, epiwafer, and MOCVD equipment suppliers, as well as for investors.
