In the present paper, we propose a method to fabricate a ''micro-collimator'' with a thickness of 15 mm. A commercially available PADC film with a thickness of 100 mm was first chemically etched with NaOH/ethanol solution to obtain a thin PADC film. This thin PADC film was then irradiated by 5 MeV a
