Claim Text:
1. A solid-state imaging device, comprising: a color filter including a first color filter segment having a first height measured from a bottom surface of the first color filter segment to a top surface of the first color filter segment; and a second color filter segment having a second height measured from a bottom surface of the second color filter segment to a top surface of the second color filter segment; a partition disposed between the first and second color filter segments and having a third height measured from a bottom surface of the partition to a top surface of the partition, wherein the partition has a refractive index lower than those of the first and second color filter segments, and the third height is smaller than the first and second heights; and a color filter underlying layer disposed between the color filter and a semiconductor substrate, wherein the color filter underlying layer is surrounded by the partition and the color filter underlying layer comprises an anti-current leakage layer formed on the semiconductor substrate and an anti-reflection layer formed on the anti-current leakage layer, and the color filter is in direct contact with the anti-reflection layer, wherein the partition is formed on the semiconductor substrate and the bottom of the partition is disposed on the top surface of the semiconductor substrate, and wherein each of the first and second color filter segments includes a flat bottom surface, a side surface in contact with the partition and an upper portion above the side surface, each of the upper portions includes an inclined surface from the top surface of the partition toward each of the top surfaces of the first and second color filter segments, the inclined surfaces of the first and second color filter segments are connected at a contact point directly on the top surface of the partition and completely cover the top surface of the partition.
