Abstract This paper introduces a novel, ecofriendly, and cost‐effective method to create deformation patterns on vertically vibrating thin film surfaces using resonant sessile droplets. The key findings emphasize the critical role of frequency vibration velocity in formation these deformations. Through theoretical experimental investigations aluminum film, it is validated that deformations are influenced by energy distribution within Specifically, higher‐order frequencies produce more concentrated at droplet's center due internal top‐down flow behaviors, resulting various states. By observing regularities width patterns, underlying phenomena elucidated, derive related empirical formulas. demonstrates significant potential for surface microstructure fabrication. ability control shapes adjusting parameters crucial optimizing microfabrication processes.
