- the resin layer 150 can be formed of a resin such as polyimide, epoxy, silicon, and benzocyclobutene.
- a forming method it is preferable to apply a dipping method, a roll coating method, a spray method, a vapor deposition method, a coating method, or the like, or a spin coating method.
- the resin does not adhere to, for example, the surface of the base metal layer 146, the resin can be selectively removed using a solvent, plasma, etching, or the like.
- the entire surface of the base metal layer 146 may be once covered with the resin, and then the resin may be removed until the upper surface of the base metal layer 146 is exposed.
- the surface of the base metal layer 146 may be exposed by mechanically polishing and grinding the resin.
- bumps 200 are provided on the base metal layer 146.
- a cream solder may be placed on the underlying metal layer 146 by screen printing or individual supply, and heated to form the ball-shaped bumps 200.
- molten solder may be supplied individually, or ball-shaped solder may be supplied and heated.
- the conductive layer 148 is deformed by the thermal stress, and the base metal layer 146 is also deformed. Since the resin layer 150 is provided around the conductive layer 148, much of the thermal stress is applied to the base metal layer 146 more than the conductive layer 148, and the base metal layer 146 Because it can be deformed significantly, it can absorb thermal stress. As a result, the thermal stress applied to the conductive layer 148 is reduced, Conduction failure due to shearing of the conduction layer 148 can be suppressed.
- FIG. 7A to 8C are views showing a method for manufacturing a semiconductor device according to the third embodiment of the present invention.
- a resin layer 160 is formed by opening a region on the wiring 120 where the conductive layer is formed as an opening 162.
- the conductive paste 168 includes a conductive filler dispersed in a binder.
- the plurality of openings 162 can be filled with the conductive paste 168 at a time.
- dispensing printing may be performed. Dispense printing is suitable when the opening 16 2 is deep.
- the conductive paste 168 is heated to harden the binder.
- the binder may be baked or the conductive filler may be melted.
- the conductive paste 168 may be irradiated with laser. As a result, the conductive paste 168 comes into surface contact with the wiring 120, so that a conductive layer 100 closely adhered to the wiring 120 is formed. According to the above steps, the conductive layer 170 can be formed without a plating process.
- a metal foil 172 provided with an adhesive is adhered on the conductive layer 170 and the resin layer 160 so as to avoid a contact portion with the conductive layer 170.
- This step is performed under vacuum.
- the atmospheric pressure is set to the atmospheric pressure, and as shown in FIG. 8B, the space between the conductive layer 170 and the metal foil 1 ⁇ 2 is evacuated, and the conductive layer 1 And close contact Let it. By doing so, the resistance between the conductive layer 170 and the metal foil 1 ⁇ 2 decreases.
- the metal foil 17 2 is patterned into the shape of the underlying metal layer 1 ⁇ 6. Thereafter, a bump is provided on the base metal layer 176.
- the conductive layer 170 is made of a conductive paste, but the base metal layer 176 is interposed, so that the conductive paste does not directly contact the bump. Therefore, for example, silver paste is used as the conductive base, and solder is used as the material of the bumps, so that even if both are melted by heat, they do not mix.
- the base metal layer 176 can be easily formed by attaching and patterning the metal foil 172.
- FIG. 9 shows a circuit board 1000 on which the semiconductor device 1 according to the present embodiment is mounted.
- an organic substrate such as a glass epoxy substrate is used for the circuit board 100.
- wiring patterns 110 made of, for example, copper are formed so as to form a desired circuit, and these wiring patterns and bumps 200 serving as external terminals of the semiconductor device 1 are formed.
- the electrical continuity is achieved by mechanically connecting 0 and 0.
- the semiconductor device 1 has a function of alleviating a thermal stress caused by a difference between a coefficient of thermal expansion of the circuit board 100 and a coefficient of thermal expansion of the semiconductor element.
- FIG. 10 shows a notebook personal computer as an electronic device 1200 having the semiconductor device 1 to which the present invention is applied.
- the constituent element "semiconductor element” of the present invention is replaced with “electronic element”, and an electronic element (regardless of active element or passive element) is mounted on a substrate in the same manner as a semiconductor chip. Can also be manufactured. Electronic components manufactured using such electronic elements include, for example, a resistor, a capacitor, a coil, an oscillator, a filter, a temperature sensor, a summit, a paris, a volume or a fuse.
