Halbleiteranordnung mit Kontaktlöchern

摘要

An electrode terminal (5) provided on a surface of a semiconductor chip (4) has a square shape in plane view. Further, the projecting apex portion (8a) of a bump (8) provided on the electrode terminal (5) orients to a corner portion (5a) of the electrode terminal (5). Hereupon, a gold ball (2a) formed by melting the lower end portion of a gold wire (2) supplied through a capillary (1) is joined to the electrode terminal (5), and then the capillary (1) is moved in the direction of a diagonal line of the square electrode (5). Thus, the main portion of the gold wire (2) is separated from the gold ball (2a) so that the bump (8) is formed.
