Abstract
Systems and methods for providing a solid state image sensor (30) are provided. More particularly, an image sensor (30) that suppresses color mixing is provided. Moreover, embodiments of the present disclosure provide for the creation of light blocking features (32) that avoid the creation of stress concentrations. More particularly, embodiments of the present disclosure provide for the creation of light blocking structures (32) using trenches formed in a substrate (44) that are arranged such that no two trenches intersect one another.
Claims20
An image pickup device, comprising:
- a substrate;
- a plurality of pixels formed in the substrate;
- and
- a plurality of trenches formed in the substrate and extending at least partially between pairs of pixels included in the plurality of pixels, and wherein at least two trenches in the plurality of trenches are formed along at least a first line that extends between a plurality of pixels.
An image pickup device, comprising:
- a substrate;
- a plurality of pixels;
- and
- a plurality of trenches formed in the substrate, wherein at least some of the trenches are between adjacent pairs of pixels, and wherein no one trench extends across any other trench.
An imaging device, comprising:
- a substrate;
- a plurality of pixels formed in the substrate;
- a plurality of trenches formed in the substrate, wherein at least some of the trenches extend between pairs of the pixels;
- a substrate light shielding material, wherein the substrate light shielding material fills the trenches included in the plurality of trenches, wherein with respect to each pixel in the plurality of pixels there exists at least one gap in the substrate light shielding material.
