Abstract:
A film carrier comprising a plurality of generally planar film carrier members that are connected, via folding parts, in the direction of an extension of each plane, wherein one of said film carrier members is a base member and the film carrier members other than the base member are laminated on the base member upon folding the film carrier at the folding parts to form a single laminate structure as a whole, said film carrier members having conductive circuits connected to a conductive circuit in the base member through inside portions of the folding parts, said base member having a mounting plane and a connection plane on the rear surface thereof, and said connection plane having a connection part which is used for connection with an external substrate and which is electrically continuous with the conductive circuit;wherein each of said film carrier members comprises a conductive circuit formed in an insulating substrate, at least one surface of the insulating substrate being a mounting plane on which to mount a semiconductor element, and the mounting plane having a mounting connection part being electrically continuous with the conductive circuit; andwherein each of the film carrier members is shaped as a square, and the film carrier members other than the base member are respectively connected to four sides of the base member.
