Abstract

Anodization of aluminium is very well known method to produce thick protective layers of aluminium oxide on aluminium metal. Characteristics of produced aluminium oxide layer depend strongly of anodization parameters (acid, acid concentration, anodizing current, and temperature) [1-3]. We have produced thin (5-50 nm), insulating layers, with different acids and acid concentrations. We have also used ALD and plasma oxidation methods to produce aluminium oxide layers with similar thicknesses. Quality of the insulating layers produced by different methods is compared, as well as the operation as gate dielectric in finished TFT.
