SOLID-STATE IMAGING DEVICE

摘要

A solid-state imaging device includes: light-receiving elements; and first dispersive elements on a light-incident side of the light-receiving elements. Each first dispersive element includes first and second light transmissive film materials. The second light transmissive film material has a refractive index that is lower than that of the first light transmissive film material in a first wavelength range and higher than that of the first light transmissive film material in a second wavelength range longer in wavelength than the first wavelength range. A volume occupation ratio of the first light transmissive film material in each dispersive element increases from one end towards the other end of the dispersive element in a direction parallel to a light-receiving surface, while a volume occupation ratio of the second light transmissive film material in the dispersive element increases from the other end towards the one end in the direction.

1. A solid-state imaging device comprising:
a plurality of light-receiving elements each of which photoelectrically converts incident light; and a plurality of dispersive elements disposed on a light-incident side of the light-receiving elements, wherein each of the dispersive elements includes: a first light transmissive film material; and a second light transmissive film material with a property of having a refractive index that is lower than a refractive index of the first light transmissive film material in a first wavelength range of the incident light and higher than the refractive index of the first light transmissive film material in a second wavelength range of the incident light, the second wavelength range being longer in wavelength than the first wavelength range, and a volume occupation ratio of the first light transmissive film material in the each of the dispersive elements increases from one end of the each of the dispersive elements towards an other end of the each of the dispersive elements in a direction parallel to a light-receiving surface of the light-receiving elements, while a volume occupation ratio of the second light transmissive film material in the each of the dispersive elements increases from the other end towards the one end in the direction, the other end being opposite the one end.
