Patent ID: 8524594

Claim:
A method for manufacturing a solid-state imaging device, the method comprising: forming pixels that receive incident light in a pixel array area of a substrate; forming pad electrodes in a peripheral area located around the pixel array area of the substrate; forming a carbon-based inorganic film on an upper surface of each of the pad electrodes including a connection surface electrically connected to an external component; forming a coated film that covers upper surfaces of the carbon-based inorganic films; and forming an opening above the connection surface of each of the pad electrodes to expose the connection surface, wherein the opening formation includes forming a resist pattern on an upper surface of the coated film, the resist pattern having openings corresponding to the connection surfaces and covering portions other than the connection surfaces, etching the coated film by using the resist pattern as a mask and the carbon-based inorganic films as etching stopper films to expose the upper surfaces of portions of the carbon-based inorganic films that correspond to the connection surfaces, and performing ashing on the resist pattern and the portions of the carbon-based inorganic films that correspond to the connection surfaces to simultaneously remove the resist pattern and the portions of the carbon-based inorganic films that correspond to the connection surfaces.
