Abstract:
1. A method for manufacturing a semiconductor device, comprising: providing a semiconductor substrate with a scribe lane and a chip area in which a plurality of metal wiring layers are formed; forming a dielectric film on the semiconductor substrate; forming a first conductive film on the dielectric film in the chip area; forming an alignment mark on the dielectric film in the scribe lane; forming a first passivation film and a second passivation film on an entire surface of the semiconductor substrate including the first conductive film and the alignment mark sequentially, wherein the first passivation film and the second passivation film have different etch selectivities; exposing the first conductive film by removing the first passivation film and the second passivation film corresponding to a portion for a bonding pad in the chip area; forming a second conductive film on the portion for the bonding pad to electrically connect with the first conductive film; forming a third passivation film on the entire surface of the semiconductor substrate including the second conductive film; selectively removing the third passivation film of the portion for the bonding pad; and selectively removing the second passivation film and the third passivation film in the scribe lane.
