Abstract
A solid-state imaging device and a method for manufacturing the same are provided. The solid-state imaging device includes a structure that provides a high sensitivity and high resolution without variations in spectral sensitivity and without halation of colors, and prevents light from penetrating into an adjacent pixel portion. A plurality of photodiodes are formed inside a semiconductor substrate. A wiring layer includes a laminated structure of an insulating film and a wire and is formed on the semiconductor substrate. A plurality of color filters are formed individually in a manner corresponding to the plurality of photodiodes above the wiring layer. A planarized film and a microlens are sequentially laminated on each of the color filters. In the solid-state imaging device, each of the color filters has an refraction index higher than that of the planarized film and has, in a Z-axis direction, an upper surface in a concave shape.
