Solid-state imaging device with on chip lenses with adjust characteristics to render pixel output sensitivities more uniform
Abstract:
A solid-state imaging device includes: an imaging unit wherein a plurality of light sensing units formed in a matrix and a plurality of interconnections are formed among the plurality of light sensing units; a color filter that is disposed over the imaging unit, and delivers colors to the light sensing units in accordance with a predefined rule; and on-chip lenses that are disposed corresponding to the light sensing units on a one-by-one basis over the color filter, and have light-collection characteristics varying in accordance with differences among sensitivities of the light sensing units, where the differences among the sensitivities of the light sensing units are generated, when the same colors are delivered to the light sensing units in accordance with the same rule, owing to the fact that positions of the individual interconnections relative to the light sensing units vary periodically.
