As a method for connecting the external lead, a wire bonding technique in which a conductive metal wire is stretched in a loop shape between the two is generally adopted.

の様々な問題が生じている。On the other hand, in response to the recent demand for higher integration and miniaturization of semiconductor integrated circuits, the density of electrodes formed on a chip has increased dramatically, and adjacent bonding wires have been formed. The distance between each other and the wire diameter are steadily becoming finer, which causes a short circuit due to the contact between the bonding wires or the contact between the bonding wire and the edge of the semiconductor chip, and the wire due to the decrease in the rigidity of the bonding wire. Various problems such as loop abnormality are occurring.

ンディング作業性の悪化等の新たな問題が発生する。In order to deal with such a problem, it is effective to make the bonding wire thinner, that is, to make the wire diameter 10 μm or less, which is much smaller than the current lower limit of 25 μm. When an element is used to make a wire having a diameter of 10 μm or less, disconnection is likely to occur during bonding due to a decrease in wire strength, which causes new problems such as a decrease in productivity and a deterioration in bonding workability.

Examples of the material include a metal material having a high tensile strength. Among them, it is preferable to use a thermoplastic synthetic resin or a thermoplastic synthetic fiber because it is softened by heat to facilitate bonding.
