Abstract
An image sensor including a substrate including first portions containing photodetectors adapted to capturing a radiation and second portions containing electronic components located between come of the first portions; a pixelated filter including filter pixels, at least some of which include an interference filter including a stack of planar layers; and shields reflecting or absorbing said radiation covering the second portions and including walls reflecting or absorbing said radiation extending between filter pixels along at least a portion of the height of the pixelated filter.
Claims14
An image sensor comprising:
- a substrate comprising first portions containing photodetectors adapted to capturing a radiation and second portions containing electronic components located between some of the first portions;
- insulation trenches extending in the substrate and delimiting the first and second portions;
- a pixelated filter comprising filter pixels having at least certain components comprising an interference filter comprising a stack of planar layers;
- and
- shields reflecting or absorbing said radiation covering completely the second portions and comprising walls reflecting or absorbing said radiation extending between filter pixels over at least a portion of the height of the pixelated filter.
