Abstract(in English) | By using AlN single layer, SiN single layer, or SiN/AlN bilayer structure, we have investigated surface passivation of AlGaN/GaN heterojunction field-effect transistors on sapphire substrates. Although the AlN passivation suppresses the drain current decrease at high drain voltage due to self-heating reduction, a deterioration of the off-state and the subthreshold characteristics is observed. On the other hand, the SiN passivation is less effective for the self-heating reduction, but does not deteriorate the off-state and the subthreshold characteristics. The SiN/AlN bilayer passivation does not deteriorate the off-state and the subthreshold characteristics, and is slightly effective for the self-heating reduction. |
