Recent Progress on Thermal Management of Ultrawide Bandgap Gallium Oxide Power Devices
摘要
Abstract
The low thermal conductivity of ultrawide bandgap(UWBG)gallium oxide(β-Ga2O3)is the most significant bottleneck restricting the development of its power devices,posing a huge challenge for efficient heat dissipation under high-power density conditions.Therefore,developing new thermal management and packaging technologies is extremely urgent.It is crucial to alleviate the performance and reliability issues caused by self-heating through thermal management at the material,device,and packaging levels.This paper provides a timely review of the state of the art in thermal management of UWBGβ-Ga2O3 power devices,discussing related challenges,potential solutions,and research opportunities.The paper firstly introduces the characteristics of UWBG β-Ga2O3 and its significance in electronic devices,and elaborates on the crucial firstly importance of thermal management in β-Ga2O3 devices.Then,various thermal management techniques,including substrate-related methods and junction-side thermal management techniques,are thoroughly examined,and their impact on the electrical properties of β-Ga2O3 devices is analyzed.Finally,the future development trends of thermal management for UWBG β-Ga2O3 devices are prospected.Multi-dimensional thermal management strategies are proposed,focusing on"material-device-packaging"electrothermal collaborative design,near junction heterogeneous integration,and novel external packaging,aiming to arouse relevant research and accelerate the development and industrialization process of UWBGβ-Ga2O3 power devices.关键词
