发明名称 Method for manufacturing solid-state image pickup device
摘要 A method for manufacturing a solid-state image pickup device that includes a pixel portion and a peripheral circuit portion, includes: forming a first insulating film in the pixel portion and the peripheral circuit portion, forming a second insulating film above the first insulating film, etching the second insulating film in photoelectric conversion elements, forming a metal film on the etched second insulating film in the photoelectric conversion elements and on the second insulating film in the peripheral circuit portion, and removing the metal film in the peripheral circuit portion and forming light-shielding films from the metal film in the photoelectric conversion elements.
