    摘要: There is provided a method for manufacturing a lead frame which can easily manufacture a high quality lead frame.A pattern layer is selectively formed on a copper plate and the surface of the substrate having formed this pattern layer is then plated with gold to form a gold layer using the pattern layer as the mask. Next, the gold layer is then plated with copper to form a copper layer, thereby forming a fine lead consisting of two layers of gold layer and copper layer. Thereafter, the pattern layer is selectively removed, an insulated resist film is formed and the copper plate is etched. In this case, the gold layer is used as the etching stop layer. Thereby, the lead frame having the fine lead of double-layer structure can be formed.

    摘要: A reinforcing ring surrounding a semiconductor element connected electrically to respective interconnecting portions through electrodes is provided as one body through suspending portions. A film circuit is produced by forming a ring in place of an outer lead for instance by applying a lead frame forming technique in which a laminate of three layers or more is used as a base, an inner lead is formed on one side and an outer lead is formed by a surface layer on another side. In this manner, in a film circuit composed of an insulating film and a plurality of interconnecting portions (leads) electrically connecting between electrodes and other electronic components of a semiconductor element on at least one principal plane of the insulating film, it is made possible to align a ring surrounding a semiconductor element with respect to the semiconductor element only by placing the film circuit on the semiconductor element, and in its turn to reduce assembly mandays of a semiconductor device.
