An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, the same symbols as in FIG. 4 indicate the same parts, and 8 is the wire bonding arm 2.
A press arm 9 provided next to the press arm 8 is a press head that is attached to the tip of the press arm 8 and has a rectangular through hole 9b in the center.
This press head 9 has a conductor 6 on the stitch side of the sample.
A rectangular frame-shaped convex portion 9a having substantially the same shape as the pattern, that is, a rectangular frame-shaped convex portion 9a having a rectangular through hole 9c in the center is provided, and is made of a material that easily transmits ultrasonic waves. The through hole 9b is provided so that the IC chip 5 can enter therein during pressing. The press arm 8 and the press head 9 constitute a stitch-side conductor flattening means 30 for pressing and applying ultrasonic waves to the stitch-side conductor 6. It is provided upstream of 7.

高いボンデイング強度を得ることができる。 In this apparatus, before wire bonding, the press head 9 is pressed against the sample as shown in FIG. 1, that is, so that its convex portion 9a is in contact with the stitch-side conductor 6, and press ultrasonic waves are applied. As a result, the stitch-side conductor 6, which had a convex shape before pressing as shown in FIG. 3c, becomes flat after pressing as shown in FIG. 3b. Then, when wire bonding is performed by the bonding means 20 on the sample sent from below the stitch-side conductor flattening means 30 to below the bonding means 20 by the sample feeding table 7, the adhesion is good.
That is, wire bonding can be performed without stitch peeling. As a result, with this device, high bonding strength without variation can be obtained by simply modifying the device by adding the stitch-side conductor flattening means 30.

As described above, according to the present invention, variations in wire bonding strength can be suppressed by adding a stitch-side conductor flattening means that presses or presses and applies ultrasonic waves to the stitch-side conductor to the conventional wire bonding apparatus. Bonding with good adhesion can be achieved, and this can be achieved with only simple modification of the equipment.
