abstract = {We report on the technology of a very thin oxidized Al
sputtered film used for gate insulation and passivation in
Al2O3/AlGaN/GaN metal-oxide-semiconductor heterostructure
field-effect transistors (MOSHFETs). Their transport
properties are presented. The MOSHFET with the Al2O3 layer
had improved static output and transfer characteristics
compared with the reference heterostructure field-effect
transistors (HFETs): (1) their saturation drain current I-DS
was similar to 600 mA mm(-1) at gate voltage V-G = 1 V
(HFETs with 2.5 mu m gates had similar to 430 mA mm(-1));
(2) their transconductance was 116-140 mS mm(-1) (HFETs had
similar to 70 mS mm(-1)). (C) 2010 The Japan Society of
