    摘要: An image sensor and a method for fabricating the image sensor are provided. The method for fabricating the image sensor includes forming a first insulating layer on a semiconductor epitaxial layer having multiple pixel regions; patterning a portion of the semiconductor epitaxial layer and the first insulating layer in a boundary region between the pixel regions to form a trench; forming a buried insulating layer on the first insulating layer, filling the trench, the buried insulating layer having a planar top surface; forming a second insulating layer on the buried insulating layer; forming a first mask pattern on the second insulating layer, the first mask pattern defining an opening overlapping the trench; and performing an ion implantation process using the first mask pattern as an ion implantation mask to form a first type potential barrier region in a bottom of the trench.

    摘要: A back-illuminated image sensor may include a substrate in which photodiodes are disposed; an insulating layer on a first surface of the substrate; an interconnection layer in the insulating layer; an anti-reflection layer between the substrate and the insulating layer; a plurality of color filters on a second surface of the substrate opposite to the first surface; and a microlens on the color filters. Because the anti-reflection layer may be between the substrate and an interlayer dielectric layer, the reflection rate of light that passes through the substrate and arrives at an interface between the substrate and the interlayer insulating layer may be reduced.

    摘要: Provided are an image sensor and a method of forming the image sensor. The image sensor has a base multi-layered reflection layer interposed between a photodiode and an interlayer insulating layer. The photodiode has a first surface adjacent to the interlayer insulating layer and a second surface opposite the first surface. Here, external light is incident on the second surface of the photodiode. Also, the image sensor includes a sidewall multi-layered reflection layer that encloses the photodiode.
