Image sensor comprising a color separation device separating incident light into plural of colors for having improved light utilization efficiency and method of manufacturing the same |
摘要 |
An image sensor including a color filter array layer, which includes a plurality of color filters transmitting light of different colors; and reflective partitioning walls, which define the color filters and have a lower refractive index than that of the color filters; a color separation device, which separates incident light into a plurality of colors, such that the plurality colors are incident on the plurality of color filters, respectively; and a sensor substrate, on which a plurality of light detection devices for respectively sensing light transmitted through the plurality of color filters are arranged in an array shape. |

1. An image sensor comprising:
a sensor substrate comprising a plurality of light detection devices arranged in a two-dimensional array; a color filter array layer disposed on the sensor substrate, the color filter array layer comprising:
a plurality of color filters, which transmit light of a plurality of colors; andreflective partitioning walls, which separate the plurality of color filters, wherein a refractive index of the reflective partitioning walls is lower than a refractive index of the plurality of color filters; a color separation device, which separates incident light into the plurality of colors and transmits the plurality of colors onto the plurality of color filters. |
