Abstract
PURPOSE: To obtain a stable lead frame by bending the end of each lead in the direction approaching the substrate electrode.
CONSTITUTION: By press forming, the areas of ends 15 of inner leads 14, 16 of the lead frame are made smaller than the area of electrode 5 of semiconductor device 4, and further, these ends are pressed downward and their surfaces of contact are made nearly parallel to each other. By this, connection between the semiconductor device and the lead frame is made easy, and further, when the lead frane is given a desired plating, connection is further facilitated, so that connection can be made without impairing the characteristics of the semiconductor device.
