| titleOfInvention | Optical waveguide and its manufacturing method |
| abstract | In order to provide an optical waveguide that can be improved in production efficiency and excellent in workability and production stability, and to provide an optical waveguide manufactured by the optical waveguide manufacturing method, a fluorene derivative and a fluorene derivative are formed on the under cladding layer 2. The varnish of the photopolymerizable resin composition containing a photoacid generator is apply | coated and dried, and the resin layer 4 without surface adhesiveness is formed. The photomask 5 is made to contact this resin layer 4, and after exposing the resin layer 4 by the contact exposure method, it develops and the resin layer 4 is pattern-formed. Thereafter, the resin layer 4 is cured to form the core layer 3, and thereafter, the overclad layer 6 is formed on the under clad layer 2 so as to cover the core layer 3 to form an optical waveguide. Get According to this method, since the resin layer 4 with no surface adhesiveness can be formed and exposed by the contact exposure method, it is possible to reduce the number of steps such as interposing a spacer and troublesome labor, thereby improving production efficiency. Improvement can be aimed at. |
