Summary:We present a controlling technique of a microporous structure by laser irradiation during the self-organization process. A polymer solution was dropped on a substrate at a high humid condition, and the honeycomb structure of regularly aligned pores on the film was fabricated by attaching water droplets on the solution surface. We demonstrated that it was possible to prevent the forming of pores at the region of laser irradiation and the flat surface was fabricated. We also demonstrated a combination structure with two sizes of pores by laser irradiation. Our method is a unique microfabrication processing technique that combines the advantages of bottom up and top down techniques. This method is expected to be applied to photonic crystals, biological cell culturing, surface science and electronics fields, etc.
