Electrical performance and reliability analysis of vertical gallium nitride Schottky barrier diodes with dual-ion implanted edge termination
In this study, a gallium nitride (GaN) substrate and its 15 μm epitaxial layer were entirely grown by adopting the hydride vapor phase epitaxy (HVPE) technique. To enhance the breakdown voltage (VBR) of vertical GaN-on-GaN Schottky barrier diodes (SBDs), a dual ion coimplantation of carbon and helium was employed to create the edge termination. The resulting devices exhibited a low turn-on voltage of 0.55 V, a high Ion/Ioff ratio of approximately 109, and a low specific on-resistance of 1.93 mΩ cm2. When the ion implantation edge was terminated, the maximum VBR of the devices reached 1575 V, with an average improvement of 126%. These devices demonstrated a high figure of merit (FOM) of 1.28 GW cm–2 and showed excellent reliability during pulse stress testing.
