Image sensing device and method for fabricating the same

摘要

An image sensing device includes: an active layer with a plurality of photo-sensing elements; a color pattern disposed over one of the photo-sensing elements, wherein the color pattern has a color selected from the group consisting of red (R), green (G), and blue (B); a microlens disposed on the color pattern; and a transmissive pattern being adjacent to the color pattern and over another one of the photo-sensing elements, wherein the transmissive pattern includes a color filter portion and a microlens portion, and an absolute value of a difference of refractive indexes between the microlens and the color pattern is less than 0.3, and there is no difference of refractive indexes between the microlens portion and the color filter portion of the transmissive pattern.

1. An image sensing device, comprising:
an active layer with a plurality of photo-sensing elements; a color pattern disposed over one of the photo-sensing elements, wherein the color pattern has a color selected from the group consisting of red (R), green (G), and blue (B); a microlens disposed on the color pattern; a transmissive material including a surface; and a transmissive pattern, included within the transmissive material, being adjacent to the color pattern and over another one of the photo-sensing elements, wherein the transmissive pattern comprises a color filter portion and a microlens portion, and an absolute value of a difference of refractive indexes between the microlens and the color pattern is less than 0.3, and there is no difference of refractive indexes between the microlens portion and the color filter portion of the transmissive pattern, wherein the color pattern is formed between a bottom surface of the microlens and the active layer, and the color filter portion of the transmissive pattern is formed between a bottom surface of the microlens portion of the transmissive pattern and the active layer; wherein there is a height difference between top surfaces of the microlens and the transmissive material.
