Abstract:
1. A solid-state imaging device comprising: a plurality of pixels, each having a microlens, each microlens comprising a first lens layer, and a second lens layer on the first lens layer, the microlenses having interpixel gaps between them; and a light blocking layer between the pixels in alignment with the interpixel gaps, wherein each of the first lens layer and the second lens layer has a thickness greater than zero throughout the interpixel gaps, the second lens layer is formed at least at a periphery of each microlens, and either any portion of the second lens layer present at a central portion of each of the microlenses is thinner than any portion of the second lens layer present at the periphery of the microlens or no portion of the second lens layer is present at the central portion of each of the microlenses.
