Solid state imaging device and method of manufacturing the same |
摘要 |
In a solid state imaging device having light receiving sections arranged in horizontal and vertical directions with different pitches, an on-chip micro-lens having a focusing efficiency optimized in both horizontal and vertical directions is formed. The solid state imaging device comprises a plurality of light receiving sections (42) arranged in horizontal and vertical directions with different pitches, a foundation layer (47) formed over the light receiving sections (42) and having convex portions on portions between the light receiving sections (42) in a fine pitch direction and having concave portions at least along a straight line connecting centers of the light receiving sections in a coarse pitch direction, and a plurality of lenses (48) formed on the concave portions so as to at least partially overlap on the convex portions in correspondence with the light receiving sections (42).
