Topological structure of thick anodic aluminum oxide

The paper examines the possibility of obtaining topological structures from thick anodic alumina using a dry photoresist mask. A hypothesis for the oxide distribution under the photoresist is proposed and the model is compared to the experimental results using pillar and hole patterning. It is shown that the shape of the pattern curvature on growing anodic oxide has a significant effect on the stability of the photoresist.
