Definitions
- the present invention relates to a semiconductor device and a method for manufacturing the same, and more particularly to a semiconductor device and a method for manufacturing the same that have improved connection reliability using fine metal wires.
- FIG. 14 is a plan view of the semiconductor device 100 as viewed from above, and FIG. 15 is a cross-sectional view thereof.
- Reference numeral 103 shown by a rectangle is a semiconductor chip, which is described here by a transistor device.
- the semiconductor chip 103 for example, a bipolar transistor, a MOS transistor, or the like is employed.
- the semiconductor device 100 three electrodes that are electrically connected to the semiconductor chip 103 are built.
- the island-shaped electrode 10 0 2 A that is electrically connected and fixed to the back surface of the semiconductor chip 10 3 is located at the left end, and two electrodes 1 0 2 B and 1 0 2 C are located at the right end.
- the electrode 10 2 A serves as a collector electrode
- the other electrodes 10 02 B and 10 02 C serve as an emitter electrode and a base electrode.
- the two bonding pads of the semiconductor chip 103 are connected to the electrodes 10 2 C and 10 2 B via the metal thin wires 10 A and 10 B, respectively.
- the electrodes 1 0 2A, 1 0 2 B, 1 0 2 C, the semiconductor chip 1 0 3, the fine metal wires 1 0 5 A and 1 0 5 B are integrally sealed with a sealing resin 1 0 1 Yes. Further, a part of the electrodes 1 0 2 A, 1 0 2 B, 1 0 2 C is exposed to the outside from the sealing resin 1 0 1.
- FIG. 1 and FIG. 2 of Japanese Patent Application Laid-Open No. 9-2 9 8 2 5 6 the inner lead is 2 PT / JP2007 / 069427
- the package placed on both sides of the card is shown, but as is clear from Fig. 2, the fine metal wire also draws a parabola, limiting the thickness of the package. Disclosure of the invention
- the planar shape of the metal fine wire 10 05 A located above the paper is convex in the direction of the gate 106, and the metal fine wire 10 1 located below
- the planar shape of B is convex in a direction away from the gate 106. Therefore, when resin is injected from the gate 106, a force that presses the connecting portion acts on the connecting portion between the metal thin wire 10 A, the electrode 100 A, and the semiconductor chip 103. This pressing force is unlikely to break the connecting portion of the metal wire 10 A.
- the metal thin wire 10 5 B is K-shaped in the direction of the gate 10 6, when the resin pressure acts on the metal thin wire 1 0 5 B, the metal thin wire 1 0 5 B becomes Tensile stress acts on the connection points with other members. Since the connection point of the metal thin wire 10 5 B is vulnerable to tensile stress, the connection point of the metal fine wire 10 5 B is likely to be broken by the resin pressure. Small devices such as portable terminals such as mobile phones tend to be light, thin, and small, and various semiconductor packages mounted on these devices are also desired to be thin.
- the present invention includes a semiconductor chip, an electrode provided around the semiconductor chip, a metal wire connecting the bonding pad on the semiconductor chip and the electrode, the semiconductor chip, the electrode, and the metal wire.
- the sealing resin is injected into one side of a cavity constituted by a mold, and the metal thin wire is directed toward the injection port. And is curved in a convex shape in a plane.
- the method of manufacturing a semiconductor device includes a step of connecting a bonding pad provided on an upper surface of a semiconductor chip and an electrode adjacent to the semiconductor chip with a thin metal wire; A semiconductor chip, the fine metal wire and the electrode are accommodated, and a sealing resin is injected into the cavity from a gate provided on a side of the cavity, and the semiconductor chip, the fine metal wire and the electrode are sealed.
- the planar shape of the metal thin wire is a shape that curves in a convex shape toward the upstream of the flow of the sealing resin injected from the gate. It is characterized by.
- FIG. 3 is a plan view of the thin metal wire 15 A as viewed from the upper surface of the package.
- the thin metal wire 15 A is bent in the opposite direction (upstream) to the flow direction of the resin injected from the gate (F 1 to F 3).

- a feature of the present invention is that the planar shape of the metal thin wires 15 15 and 15 5 is a shape that curves convexly toward the upstream side of the flow of the sealing resin 11 to be injected.
- the method for forming the sealing resin is as follows. First, the electrode 18 and the like, the semiconductor chip 13 and the metal thin wire 15 B are accommodated in the cavity 17 of the mold 18 comprising the upper mold 19 and the lower mold 20. Next, liquid sealing resin 11 is injected into the cavity 17 from the gate 16 (FIG. 1) provided on the mold 18. Finally, the sealing resin 11 injected as necessary is thermally cured, and then the sealing resin 11 is taken out from the mold 18. Therefore, since the liquid sealing resin 11 is injected from the gate 16, the pressure from above to below acts on the metal thin wires 15 A and 15 B on the paper surface during resin sealing. To do. If measures against this stress are not taken, the metal wires 15 A and 15 B may be deformed or disconnected.

- the fine metal wires 15 A and 15 B By forming the shape of the fine metal wires 15 A and 15 B in this way, the fine metal wires 15 A and 15 B even if pressure is applied by the sealing resin 11 injected from the gate 16 Since the force acting on the connection between the and other members is a pressing force (compression force), disconnection from this connection point is suppressed. Further, the above-described curved shape prevents the metal thin wire 15 A from being broken or deformed by reducing the force acting on the connecting portion. Details of this matter will be described later with reference to FIG.
- the shape of the thin metal wire 15 A or the like that is the point of the present invention is curved: g 69427
- the thin wire 15 A has a shape curved in a convex shape toward the gate 16 into which the sealing resin 11 is injected.

Yes (Tensile force does not act) Curved shape.
- connection portion (adhering portion 2 1) between the bonding pad of the semiconductor chip 13 and the fine metal wire 15 B is lowered. Therefore, when the pressure of the sealing resin 11 acts on the low-loop metal fine wire 15 B, the connection point (adhering portion 2 1) between the metal fine wire 15 B and the semiconductor chip 13 is broken and disconnected. There is a risk.

- the metal thin wire 15 A is made into a low loop, the shape of the metal thin wire 15 A in the vicinity of the fixing portion 21 is complicated and there is a risk of causing disconnection. By bending 1 5 A in a specific direction, disconnection can be prevented.
- F 3 acting in the vicinity of the fixed portion 22 at the lower end can also be disassembled as described above. Specifically, F 3 is decomposed into a force F 3 a in a direction parallel to the tangent of the metal thin wire 15 A near the fixed portion 2 2 and a force F 3 b in a direction perpendicular to the tangent. The Since the compressive force acting on the fixing portion 2 2 of the thin metal wire 15 A is F 3 a smaller than F 3, disconnection at the fixing portion 22 is prevented.
