Description

The onset and pinch-off voltages shift of lateral GaN field-effect rectifier diodes (L-FER) and normally-off HEMTs are studied. It is shown that a short duration of low power SF6 plasma followed by a low temperature annealing permits to get an effective and stabilized fluorine ion implantation in the AlGaN barrier, contributing to reduce the back shift of both devices threshold voltages.
