GaN Power Devices: Overcoming Manufacturing Challenges for High-Voltage Applications
By
Katherine Derbyshire
Summary
This article examines the transition of Gallium Nitride (GaN) power devices from low-voltage consumer applications (like phone chargers) to high-voltage applications such as power generation and transportation. It discusses the demanding requirements for high-voltage GaN devices, introduces Baliga's figure of merit as a key performance metric, and explores how new designs and process flows could help overcome manufacturing challenges in scaling GaN technology for high-voltage use cases.
