Fabrication method of GaN template for high-speed chemical lift-off

AIP Advances, 2023
In this study, a gallium nitride (GaN) template fabrication method for efficient chemical lift-off (CLO) is developed. CLO is slower than other lift-off methods. An air tunnel structure is formed using a photoresist to reduce the process time and improve
