Claim Text:
1. A manufacturing method of a solid-state imaging device comprising: forming a plurality of concave portions in a supporting substrate; forming a stress film on a first surface of a semiconductor wafer which includes a plurality of solid-state imaging portions; bonding the first surface of the semiconductor wafer on the supporting substrate so as to seal each concave portion in a view-angle region of each of the solid-state imaging portions, each of the view-angle regions being a region in which a light-receiving pixel of the solid-state imaging device is arranged; curving the view-angle regions of the plurality of solid-state imaging portions to a concave portions side by stress of the stress film in a state where the semiconductor wafer is thinned; and dividing the semiconductor wafer and the supporting substrate into the plurality of solid-state imaging portions.
