However, in the case of the TAB tape formed by laminating and integrating the copper foils having the above structure, there are the following practical problems. That is, the etching property of copper is poor when forming the lead pattern. Here, the poor etching property means the miniaturization of the lead pattern, in other words, the difficulty of forming the lead patterns having a narrow pitch and narrow width from each other by insulating / separating from each other. Further, in the structure of the tape carrier package, it is not possible to sufficiently cope with the reduction in size and the increase in capacity of the multi-pin type. To reduce the size of the lead pattern, there is a means to reduce the thickness of the copper foil, but since the strength or hardness of the formed lead pattern decreases, deformation or cutting is likely to occur during bending, and the tape carrier There is a problem that packaging becomes difficult. In particular, insufficient hardness of the lead pattern is likely to cause the lead pattern to lose its shape, which may cause a problem in reliability in the case of automatic mounting. Also,
The low adhesive strength to the resin film surface causes a difficulty in lead patterning work by etching, and can easily function as a carrier tape by peeling easily when the lead pattern is miniaturized. There is a problem that there is no. Furthermore, the above-mentioned problem of adhesion is
For example, when a required semiconductor element is mounted / bonded on a carrier tape and then resin-molded, there is a disadvantage that the airtight or liquid-tight sealing property cannot be exhibited. Therefore, the conventional TAB tape is naturally limited in its use. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a TAB tape suitable for the construction of a highly reliable tape carrier package having good characteristics.
