The oxidation kinetics of gallium arsenide in a humid nitrogen(I) oxid
e atmosphere and the composition of the resulting films were studied.
The presence of N2O has no effect on the rate of oxide film growth com
pared to oxidation in humid oxygen but increases arsenic content of th
e films, which improves their electrical properties, The oxidation kin
etics of GaAs depends to a significant degree on the way in which N2O
is introduced into the oxidizing atmosphere.
