<p><P>PROBLEM TO BE SOLVED: To provide a solid-state imaging device having a condensing element effective in improving sensitivity by reducing increases in condensing loss and color mixing due to an increase in angle of light entering a waveguide when the light is obliquely incident. <P>SOLUTION: The solid-state imaging device includes a substrate 6, a plurality of unit pixels disposed on the substrate 6, a wiring layer 4 formed on the plurality of unit pixels, an optical waveguide area 401 formed on photoelectric conversion areas included in the unit pixels and penetrating the wiring layer 4, and the condensing element 501 formed on the optical waveguide area 401, the condensing element 501 having an effective refractive index distribution. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
