## Abstract The local formation of porous anodic alumina (PAA) thin films on confined areas measuring few μm^2^ through an SiO~2~ masking layer on the silicon substrate has been developed. The locally grown porous anodic alumina thin films showed highly symmetric vertical cylindrical pores with a p
