Title: Multi-layered filter and its manufacture
Inventor: SOMENO YOSHIHIRO
IPC: G02B6/132
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent deformation such as curling and obtain desired optical characteristics, and facilitate handling by forming a filter frame layer which has a window on a substrate, forming a multi-layered film on the substrate in the window and the filter frame layer, and removing the substrate from the filter frame layer and multi-layered film. SOLUTION: On the substrate 1, the frame layer 2 for holding a multi-layered film filter is formed (Fig. a). Then the multi-layered film 3 having desired wavelength selectivity is formed on the substrate 1 and frame layer 2 (Fig. b). Therefore, the multi-layered film 3 in the filter window 3 is formed on the substrate 1, so the frame layer 2 and multi-layered film 3 are formed in level with each other. After they are cut into chips (Fig. c), only the substrate 1 is removed and then a filter chip F with a frame having a filter window 4 is completed (d). The circumference of the multi-layered film 3 of each filter chip F is held by the frame layer 2 and the filter window 4 surrounded with the frame layer 2 serves as a filter part having wavelength selectivity to prevent deformation such as curling.
