A semiconductor device includes a semiconductor substrate having an integrated circuit, a first insulating film formed on the semiconductor substrate, at least one power source internal wiring line formed on the first insulating film, and a second insulating film formed on the first insulating film and on the internal wiring line and having a plurality of openings exposing parts of the internal wiring line. At least one wiring line is formed on an upper side of the second insulating film to correspond to the internal wiring line and electrically connected to the internal wiring line via the plurality of openings of the second insulating film. The wiring line has at least one external electrode pad portion whose number is smaller than the number of openings in the second insulating film.

A plurality of semiconductor chips are bonded to an adhesive layer formed on a base plate. Then, first to third insulating films, first and second underlying metal layers, first and second re-wirings, and a solder ball are collectively formed for the plural semiconductor chips. In this case, the first and second underlying metal layers are formed by a sputtering method, and the first and second re-wirings are formed by an electroplating method. Then, a laminate structure consisting of the three insulating films, the adhesive layer, and the base plate is cut in a region positioned between the adjacent semiconductor chips.

A plurality of semiconductor chips (23) are bonded to an adhesive layer (22) formed on a base plate (21). Then, first to third insulating films (31, 35, 39), first and second underlying metal layers (33, 37), first and second re-wirings (34, 38), and a solder ball (41) are collectively formed for the plural semiconductor chips (23). In this case, the first and second underlying metal layers (33, 37) are formed by a sputtering method, and the first and second re-wirings (34, 38) are formed by an electroplating method. Then, a laminate structure consisting of the three insulating films (39, 35, 31), the adhesive layer (22), and the base plate (21) is cut in a region positioned between the adjacent semiconductor chips (23).

After columnar electrodes and a sealing film are formed above a semiconductor substrate in a wafer state, probe pins are brought into contact with the upper surfaces of the columnar electrodes, and burn-in is executed. Next, solder balls are formed on the columnar electrodes, and the semiconductor substrate in a wafer state is diced. As a result, any unwanted deformation of the solder balls by contact of the probe pins can be prevented. In addition, even when the heights of the solder balls vary, burn-in can be performed.

In a semiconductor device, re-wiring is provided on a circuit element formation region of a semiconductor substrate. A columnar electrode for connection with a circuit board is provided on the rewiring. A first insulating film is provided over the semiconductor substrate excluding a connection pad, and a ground potential layer connected to a ground potential is provided on an upper surface of the first insulating film. A re-wiring is provided over the ground potential layer with a second insulating film interposed. The ground potential layer serves as a barrier layer for preventing crosstalk between the re-wiring and circuit element formation region. A thin-film circuit element is provided on the second insulating film, and a second ground potential layer is provided as a second barrier layer over the thin-film circuit element with an insulating film interposed. Re-wiring is provided over the second ground potential layer.

A plating tray includes a recessed region in a central portion of an insulating substrate for arranging therein a silicon semiconductor substrate and a metal film arranged to surround the recessed region. The semiconductor substrate is housed in the recessed region. Under this condition, a dry photoresist film containing Na, K, Ca and Cu in amounts smaller than predetermined amounts is formed to cover a metal underlying film. Then, a projecting electrode is formed by electroplating within open portions formed in the resist film. In forming the projecting electrode, the open portion is also formed in that region of the resist film which corresponds to the metal film of the plating plate so as to form a dummy projection electrode simultaneously.

A low dielectric constant film/wiring line stack structure made up of a stack of low dielectric constant films and wiring lines is provided in a region on the upper surface of the semiconductor substrate except for the peripheral part of this surface. The peripheral side surface of the low dielectric constant film/wiring line stack structure is covered with a sealing film. This provides a structure in which the low dielectric constant films do not easily come off. In this case, a lower protective film is provided on the lower surface of a silicon substrate to protect this lower surface against cracks.
