Publication number: 20100084261Abstract: The present invention discloses a method for fabricating polymeric wavelength filter, which method for forming gratings patterns on the UV polymer involves three processing steps. First, a gratings pattern is holographically exposed using a two-beam interference pattern on a positive photo-resister film. A 20-nm-thick nickel thin film is then sputtered onto the positive photo-resister film to form a nickel mold. This nickel mold on the photo-resister film then can be subsequently used to transfer the final gratings pattern onto a UV cure epoxy polymer. Whereby, a polymer film can be spun coated on the cure epoxy substrate so as to simplify the fabrication process for obtaining a polymer wavelength filter with good aspect ratio of gratings pattern.Type: ApplicationFiled: October 7, 2008Publication date: April 8, 2010Applicant: China Institute of TechnologyInventors: Kun-Yi Lee, Wei-Ching Chuang, Yen-Juei Lin, Cheng-Che Lee, Wei-Yu Lee
