Abstract:
1. A semiconductor device comprising: a pixel area which is formed on a semiconductor substrate, the pixel area including pixels, and each of the pixels generating an image signal corresponding to incident light; a light-shielding layer which is formed on the semiconductor substrate around the pixel area, the light-shielding layer having a slit near the pixel area and shielding the incident light; a passivation film which is formed in the pixel area, on the light-shielding layer, and in the slit, the passivation film in the pixel area having a planar surface all over the pixels and between the pixels; a coating layer which is formed in the slit of the light-shielding layer and on the passivation film in the pixel area, the coating layer in the pixel area has a uniform thickness all over the pixels and between the pixels; and microlenses which are formed on the coating layer in the pixel area, the microlenses being arranged with respect to the pixels, respectively.
