Patent ID: 8512493

Claim:
A method of manufacturing an optical filter comprising: (a) providing a first substrate having a first reflecting film, and a first bonding area disposed in a periphery of the first reflecting film; (b) forming a first barrier film on the first reflecting film, and a first bonding film in the first bonding area; (c) providing a second substrate having a second reflecting film, and a second bonding area disposed in a periphery of the second reflecting film; (d) forming a second barrier film on the second reflecting film, and a second bonding film in the second bonding area; (e) irradiating the first bonding film with an ultraviolet ray via a first mask member or exposing the first bonding film with an ozone gas via the first mask member; (f) irradiating the second bonding film with an ultraviolet ray via a second mask member or exposing the second bonding film with an ozone gas via the second mask member; and (g) bonding the first bonding film and the second bonding film to each other to thereby bond the first substrate and the second substrate to each other, wherein in step (e), the first mask member has a first opening section located above the first bonding area, and a part of the first mask member is located above the first reflecting film, in step (b), the first bonding film includes an Si skeleton having a siloxane bond, and an elimination group connected to the Si skeleton, in step (d), the second bonding film includes an Si skeleton having a siloxane bond, and an elimination group connected to the Si skeleton, the elimination group is eliminated from the Si skeleton of the first bonding film to thereby form a dangling bond by step (e), the elimination group is eliminated from the Si skeleton of the second bonding film to thereby form a dangling bond by step (f), and in step (g), the dangling bond of the first bonding film and the dangling bond of the second bonding film are bonded to each other to thereby bond the first bonding film and the second bonding film to each other.
