Market opportunity for GaN for MOCVD and ALD

ALD and MOCVD is rapidly gaining traction in the semiconductor industry, particularly for logic, memory, and wide-bandgap power semiconductors. This growth is highlighted by industry experts at SEMICON Europa 2023. ALD is primarily adopted for its excellent surface passivation qualities, essential in GaN power electronic devices. While miniaturization drives ALD use in some sectors, its primary role in power electronics is to provide high-quality, conformal coatings, crucial for device performance and reliability. Thermal ALD processes like Al2O3 and AlON are key for GaN transistors, offering improved interface layers for low dynamic switching losses. ALD's impact is most notable in consumer, automotive, and industrial markets, where it enhances device performance and longevity. Looking forward, continued optimization of ALD processes and in-situ surface treatments are expected to further enhance device performance and reliability, especially in GaN power electronic devices, with high growth predicted in various end markets.
