Abstract: PURPOSE:To make it possible to form bump electrodes on element electrodes without using a plating step, by depositing minute metal members on a layer having photoconductiveness corresponding to the charging pattern of the layer having the photoconductiveness. CONSTITUTION:Minute metal members (minute metal balls) 16 are bonded to chip electrodes 17a of a semiconductor.

Light is projected on the layer through a mask having light screening pattern corresponding to the electrode forming part of a semiconductor chip. Thus the minute metal members 16 are attached. In this way, the layer having the photoconductiveness on the surface of the supporting body 11 is charged, and the light is projected through an electrode pattern mask for the semiconductor chip. Thus, the conductivity of a part other than the masked part is increased, and the electric charge is removed. Meanwhile, the electric charge remains at the masked part. Therefore, the dispersed minute metal particles 16 can be held. In this way, the bump electrodes can be formed without using a plating step.
