SOLID-STATE IMAGE CAPTURING DEVICE AND MANUFACTURING METHOD, AS WELL AS ELECTRONIC DEVICE

The present disclosure relates to a solid-state image capturing device and a manufacturing method as well as an electronic device that are capable of achieving better image quality. A light blocking portion is provided along wall surfaces of a slit defined in an insulating film between adjacent pixels that is provided in covering relation to a light receiving surface of a semiconductor substrate having an element-separating structure between a plurality of pixels. A low-refractive-index wall is provided between light blocking portions between adjacent ones of the pixels and provided between color filters provided above the insulating film. The present technology can be applied to a back-irradiated CMOS image sensor, for example.
