Abstract

We consider the crystallization of ITO films induced by excited atomic oxygen. Owing to it, transmittance of these films in visible ranges increased by 20% and surface impedance dropped from 36 down to 4.6Ω/□. The treatment temperature (127 °C) was significantly below that of conventional crystallization (320 °C). Application of elastic light scattering diagnostics shows that rms surface roughness increased from 2.65 nm up to 4.07 nm after film treatment. ITO treatment does not change isotropic azimuthal structure of the surface.
