Abstract

PURPOSE:To cut connecting wire without damaging semiconductor elements in cutting a wire for connecting semiconductor elemenets by using a cutting blade having a contacting part to the wire and provided with a cutting edge which is shorter than the diameter of the wire. CONSTITUTION:A wire of Al wiring that connects semiconductor elements is cut by a cutting blade 10. The cutting blade 10 is provided with a face 12 that contacts with the wire 11 at its lower end, and the length C of the cutting edge 13 is made smaller than the diameter of the wire to be cut. When cutting the wire, the contacting part 12 of the cutting blade 10 comes into contact with the wire 11 and does not go down further, and a notch 14 is formed on the wire 11 by the cutting edge 13. The wire is pulled by a wire clamping device, and cut by a pull cut method. Since the cutting edge 13 does not reach the semiconductor element, cutting can be performed without damaging the semiconductor element.

That is, as shown in Fig. 1, a semicircular chip (1,000 ox-type chips) 4.5 is mounted on the substrate 1 with waxing 2.3, and 1. the first chip is bonded by the wire 7 with the force of the bonding tool 6. 4 to the second chip 5, the wire cutting blade 8 is moved to the cutting and pasting position ml of the wire 7, and the wire cutting blade 8 is lowered (in the direction of arrow A) (~ The wire I is cut by the wire clamping device 9, and the wire 7 is clamped to the right (to the force indicated by the arrow 1) and the bonding tool 6 is pulled to the right at the same time as the wire is clamped @9. The wire I is made in a four-dimensional manner, and the wire I is not easily damaged by the bonding ink tool. Regarding the toothpicks of Al glands, thin ones with 4 bends and 4' も and Asumi can be cut using the HT pull cut (Hikichikiri) method, which is just enough to pull with a wire clamp device *9, but in the case of mkfJ20tlμψ or more, pull cut is necessary. With this method, problems such as damage and peeling of the ribboning contact layer where the wire stretches and the wire becomes thinner occur, so a pull cut method is used in conjunction with a cutter and a wire cutting blade as described above. ing.

By the way, in the above-mentioned cutting method, the wire 7 is completely cut out by the V-shaped wire 8 (as shown in Fig. 2), and the wire 7 is positioned under the wire at the π point of the V-shaped wire. For example, it will cause a loss of hot water in the chip 5 (temporary bonding @) in Figure 1 or the PN junction in the case of a half-2s body chip, and in particular, self-acupuncture bonding between wires in a hybrid IC using a relatively thick wire. Therefore, the wiring is not efficient due to the damage caused when the power is cut off.Objective of the InventionThe present invention was made based on the above-mentioned problems, and it is possible to change the design of the current equipment. Instead, it is equipped with a device that can cut even thick wires without causing damage to plate bonding products.

The g-capital invention of ``Choyu'' is to pull out the electrodes of a Ushihiro body cord, etc., use a wire cutting blade to cut out the wire, pull it apart with a clamp, and cut it. - ■ Wire cutting - In the Ti cutter, the blade for cutting III is brought into contact with the front Sd wire. This device forms a cap with the cutting edge, lowers it onto the wire to form a notch in the wire marked mlJ, and pulls it with a pick clamp the previous day to cut the wire.

Fig. 3 σ Akira Honji's wire cutting ~1 device used in 1) Fr1fr blade 1u and cutting 11. The cutting blade 1u, which is the same as the wire 11 to be subjected to JT, is provided with a contact portion 12 that contacts the wire 11 and a wire 110 formed on the right side of the wire 11 with a length smaller than the wire diameter. cutting edge 1
3, and when it is lowered from above onto the wire 11, the abutment part 12 comes into contact with the wire 11, and the cutting edge 1
3 stops in the wire 11, and there is a notch 1 in the wire 11.
4 is formed. As for the clamp (not shown), a conventional clamp as shown in Fig. 1 is used.
With this, the wire 11 with the notch 14 formed therein can be pulled cut and the working wire 11 can be cut into pieces. For example, wire bonding between chips in a high frit IC or other internal device can be described as there is little damage and no resentment.

FIG. 4 shows a modification of the cutting blade in the cutting device of the present invention. In FIG. Or the 4th
It is also possible to form abutting portions 12, 4-12' on both sets 11 of the cutting edge 13, as shown in FIG.
The negative name (C dimension) of the cutting edge in Figures and Figure 4 is the negative name (C dimension) of the wire used.
In addition, in the cutting blades shown in Figures 3 and 4, the cutting edge and the contact part are made of the same material and are formed into a single bar. For example, even if only the edge of the blade is made of a skilled material, it will not work.As is clear from the laughable heart of the 11th explanation, the wire-cutting device of the present invention will not cut the wire even if it is made of a skilled material. It is possible to move relatively thick wires from 9 directions to 1 degree without changing the width of the IC.
