ABSTRACT:
A semiconductor device and a method for manufacturing the same prevents copper from being exposed to a surface of a passivation film after a copper metal line formation, to avoid contamination of processing equipment and the process environment. The method includes providing a substrate with a scribe lane and a chip area in which metal wiring layers are formed, forming a dielectric film, forming a conductive film on the dielectric film in a chip area and an alignment mark on the dielectric film in a scribe lane, forming passivation films, exposing the conductive film by removing the passivation films in a bonding pad portion in a chip area, forming another conductive film in the bonding pad portion to electrically connect with the conductive film, forming another passivation film, and selectively removing the passivation films.
