摘要： A two-layer film carrier for TAB is made from a substrate prepared by forming a copper layer on a polyimide film by additive plating. A photoresist layer is formed on the copper layer, and another photoresist layer on the polyimide film. Both of the photoresist layers are simultaneously exposed to light through a mask applied to each of them to define a desired pattern. The exposed portions of the photoresist layer on the copper layer are subjected to development and postbaking, whereby selected portions of the copper layer are exposed. The exposed portions of the copper layer are additive plated with copper, whereby leads are formed. The exposed portions of the photoresist layer on the polyimide film are subjected to development and postbaking, whereby selected portions of the polyimide film are exposed. The remaining portions of the photoresist layer are removed from the copper layer and the underlying copper layer is etched. The exposed portions of the polyimide film are etched, and the remaining portions of the photoresist layer are removed from the polyimide film.

摘要： An optical branching element mainly composed of a central linear optical transmission line and a plurality of peripheral linear optical transmission lines. They have circular sections of approximately the same diameters. The peripheral linear optical transmission lines are provided around the central linear optical transmission line such that their end surfaces are arranged on the same plane as the end surface of the central linear optical transmission line. A holder fixes these central and peripheral linear optical transmission lines on the end surface side. Semispheric reflecting concave surfaces having radii larger than the diameters of said peripheral linear optical transmission lines are formed around the contact points of the end surface of the central linear optical transmission line and the end surfaces of the linear optical transmission lines. A reflector which is provided in opposed contact with the contacting surface of the holder incorporates a plurality of semi-spherical reflecting concave surfaces as a reflecting concave surface.
