Claim:
1. A method for manufacturing a semiconductor device, the method comprising: forming an organic film on a pad electrode; forming an inorganic film on the organic film; forming a photoresist pattern on the inorganic film for creation of an opening to the pad electrode of the semiconductor device; dry-etching the inorganic film using plasma with the photoresist pattern serving as a mask; dry-etching the organic film using plasma with the photoresist pattern serving as a mask without exposing the pad electrode; removing the photoresist pattern using a stripping solution, and; after the removing the photoresist pattern using a stripping solution, etching the organic film to expose the pad electrode with the inorganic film that remains after the dry-etching the inorganic film using plasma, wherein the inorganic film that remains after the dry-etching serves as a mask in the etching the organic film to expose the pad electrode.
