GaN devices are gaining the confidence of many customers and are penetrating various applications. This is confirmed by the promising market outlook for GaN devices having a compound annual growth rate (CAGR) of 81% for the period 2019-2025 according to Yole Développement. This relates to market forces pushing for loss reduction and improved efficiency.

Since their first commercialization in 2010, the performance of GaN devices and the value that they add have been gradually proven. Their price has also become increasingly acceptable to end users. Manufacturers use different approaches for device design, depending on the targeted electrical performance and application.

GaN devices still have some technical and commercial challenges to face. For example, both GaN wafer processing and packaging impact the price and make it the major cost-driver of a GaN device. Other challenges include the complexity of some process steps, mainly epitaxy, which hinder GaN adoption on a large commercial scale.

In this report, System Plus Consulting presents an overview of the state-of-the-art of GaN power devices. It highlights differences in design and manufacturing processes, and their impact on device size and production cost. Overall, it analyses 18 devices from ten of the main suppliers: EPC, GaN Systems, Infineon, Innoscience, Navitas, Nexperia, Panasonic, Power Integrations, Texas Instruments and Transphorm. The report includes optical and SEM pictures of the devices to understand the technological choices at die design and assembling level.

This report includes an estimated manufacturing cost of the analysed GaN devices and their selling prices. It provides physical, technological, and manufacturing cost comparisons between the analysed devices.
