Abstract:
In a semiconductor device having a plurality of its bare chips each with a pad electrode wrapped up in a wiring built-in insulation film with a plurality of external electrodes corresponding to said pad electrodes in a manner such that said pad electrodes of said bare chips are brought into electric contact with said external electrodes of said wiring built-in insulation film, the improvement wherein:said wiring built-in insulation film assumes a linearly elongated shape containing a series of linearly arranged unit films in each of which each of said bare chips is packaged;said wiring built-in insulation film is bent through an angle of approximately 180 degrees at every unit film alternately to the right and the left in a zigzag manner;each of said bare chips is packaged in each of said unit films of said wiring built-in insulation film;a plurality of said bare chips, which are packaged in said unit films of said wiring built-in insulation film thus bent in the zigzag manner, are then stacked together in the direction of thickness dimensions of said chips; andan end portion of said wiring built-in insulation film is fixed to the lowermost one of the thus stacked bare chips so as to wrap all said bare chips up in said wiring built-in insulation film.
