In the ball bonding method, as shown in FIG.
As shown in (b), the wire 2 is passed through the capillary tool 1, the tip of the wire is melted by discharge heating to form the ball 3, and the ball 3 is pressure-bonded onto the semiconductor chip 4 by the capillary tool. The diameter of the ball formed by pressure bonding is 3 to 4 times the diameter of the wire. Further, in such a ball bonding method, the wire 2 is connected to the ball 3
Since it rises almost vertically from, the wiring height becomes high. Recently, these have become a bottleneck for reducing the size of the semiconductor PKG, especially as the size of the semiconductor PKG decreases.
Japanese Patent No. 55237 describes a conventional method of performing two-point bonding on the lead side with a ball bonder. The method is shown in FIG. According to the publication, balls are formed in the same sequence as in the conventional ball bonding method, then the internal leads are bonded, and then the leads and the semiconductor chip are continuously bonded. As a result, the wire in the bonding from the lead side to the semiconductor chip has nothing to do with ball formation at the lead side rising portion, so that the wire shape to be wired can be made lower than the normal ball bonding method.

On the other hand, in the wedge bonding method, as shown in FIGS. 4 (a) and 4 (b), since the pressure bonding diameter after bonding is the wedge method, it is surely smaller than that of the ball bonding method, and the chip of the fine bonding pad is formed. in use. However, in the wedge method, the bonding direction is basically limited to a fixed direction. Therefore, in the bonding of the semiconductor chip, it is necessary to rotate the chip itself for each wire, and the bonding speed is lower than that of the ball bonding method. Absent. In this regard, Japanese Patent Publication No. 2-137341 discloses speed-up means, but does not show means for solving the above-mentioned rotation of the chip itself.

The wedge bonding method is suitable for coping with the miniaturization of the bonding pad accompanying the high integration and miniaturization of the semiconductor chip. However, as described above, the conventional method has a high bonding speed. It is a problem in terms of cost performance late. On the other hand, the ball bonding method also shows the improved method shown in FIG.
Since it is a point bonding method, it is inferior to the conventional ball bonding method, and it will still be a problem in terms of speed with respect to the trend of increasing the number of pins in the future.

According to the wire bonding method of the present invention, the wire supplied through the conical capillary tool used in the conventional ball bonding method is bent at the tip end thereof.
Prevents the wire from coming off when bonding capillaries and securely crimps the wire tip to the bonding surface.
Then, the capillary is lowered again while moving the wire in the wiring direction to complete the second bonding. After the second bonding, the capillary is raised again and the wire is cut to complete the wire wiring.

Embodiments of the present invention will be described below with reference to FIGS. The bonding wire 2 supplied through the center through hole of the conventional conical capillary 1 having a rotational axis symmetry is in a state of protruding by a length L (about 1 mm) from the tip of the capillary (FIG. 2 (a)). This wire tip 3 is connected to the vertical driving unit of the capillary by a wire bending rod 4 before the capillary processing.
By the sliding motion of (1), the lower surface of the capillary 1 is bent laterally (FIG. 2B). After this, the capillary 1 descends toward the inner lead 5 to process the bonding operation. Since the wire 2 is bent, the wire does not come off, and the wire tip portion 3 is securely crimped to the lead surface while the wire is under tension (FIG. 2 (c)).
After the first bonding, the capillary 1 rises and moves onto the semiconductor chip 6 which is the second bonding point,
After reaching the upper limit, it descends again and is pressure-bonded onto the semiconductor chip 6 (FIG. 2D). After this, the capillary 1 rises,
When the distance from the tip of the capillary to the surface of the tip 6 becomes L (FIG. 2 (e)), the wire cut clamp 7 at the upper part of the capillary is closed and the capillary is lifted to execute the wire cutting (FIG. 2 (e)). ). At this time, the wire length protruding from the tip of the capillary is L. The capillary continues to rise, the wire bending rod 4 operates near the upper limit, the wire is bent, and the capillary moves to the next bonding position (next inner lead portion), completing the bonding cycle. By repeating the above cycle, bonding between leads and semiconductor chips is performed.

Further, since the capillaries used in the conventional ball bonding method are used, the directionality is not regulated as in the case of using wedges, so that it is not necessary to rotate the chip and the bonding speed is not lowered.

As described above, the present invention realizes a wedge bonding method having omnidirectionality without forming a ball by adding a wire bending portion in the conventional ball bonding apparatus. As a result, wedge bonding can be realized at a speed equivalent to that of conventional ball bonding, and high-speed bonding with low loop and small pads, which is an advantage of wedge bonding, can be achieved. Further, in the description of the embodiments, the first bonding is the inner lead, but it goes without saying that it does not matter even if it is on the semiconductor chip side.
