Abstract:
In a solid-state imaging element having two or more photodiodes stacked in a vertical direction in each of pixels, electrons are prevented from moving between the respective photodiodes of the pixels adjacent to each other. The solid-state imaging element is formed by joining together a back surface of a first semiconductor wafer including one of the photodiodes and a wiring layer and a back surface of a second semiconductor wafer including another of the photodiodes and a wiring layer. By forming a first isolation region extending through a first semiconductor substrate forming the first semiconductor wafer and a second isolation region extending through a second semiconductor substrate forming the second semiconductor wafer, the photodiodes of one of the pixels are isolated from another of the pixels.

Claim (Index 14):
The method of manufacturing the solid-state imaging element according to  claim 9 ,\n wherein the first light receiving element photoelectrically converts light in a first wavelength region, while the second light receiving element photoelectrically converts light in a second wavelength region where a wavelength is longer than in the first wavelength region, the method further comprising the step of: (g2) before the step (g), forming a first reflection film which reflects the light in the first wavelength region and transmits the light in the second wavelength region and a fifth insulating film in this order so as to cover an exposed lower surface of the second insulating film or an exposed lower surface of the third insulating film, wherein, in the step (g), the first semiconductor substrate and the second semiconductor substrate are joined together to form the first insulating film including the second insulating film, the third insulating film, the first reflection film, and the fifth insulating film.
