PURPOSE:To facilitate the fixture of a film and to reduce the number of steps and to prevent an adhesive from exfoliating by placing a film having a filter effect on the front of a light receiving chip on leads, and simultaneously sealing with resin the chip and the film. CONSTITUTION:A film 3 having a filter effect is placed on the front of a light receiving chip 1 connected on leads 4, and the chip 1 and the film 3 are simultaneously sealed with resin 2. Since this method contains the film having filter effect, it can eliminate defects such as the difficulty of securing the film, the increase in the steps of mounting the films, and the decrease in the reliability due to the exfoliation of bonding. |
