Abstract
A device includes a substrate and a plurality of unit pixels disposed in and/or on the substrate, arranged in a honeycomb pattern and separated from one another by a deep trench isolation (DTI) layer. The plurality of unit pixels may include a group of unit pixels radially arranged around and equidistant from a central unit pixel.
Claims9
A device comprising:
- a substrate;
- and
- a plurality of unit pixels which have a hexagonal shape with rounded corners disposed in and/or on the substrate, arranged in a honeycomb pattern and separated from one another by a deep trench isolation (DTI) layer.
A device comprising:
- a substrate;
- and
- a plurality of unit pixels which have rounded corners disposed in and/or on the substrate, arranged in a honeycomb pattern and separated from one another by a deep trench isolation (DTI) layer, wherein the DTI layer includes a Y-shaped portion between adjacent first, second and third unit pixels of the plurality of unit pixels, wherein the first, second and third unit pixels are separated from one another by a distance x, and wherein a portion of the DTI layer bounded by segments connecting adjacent corners of the first, second and third unit pixels has an area S given by:
- S<x2.
1 more element
A device comprising:
- a substrate;
- and
- a plurality of unit pixels which have rounded corners disposed in and/or on the substrate, arranged in a honeycomb pattern and separated from one another by a deep trench isolation (DTI) layer, wherein each of the unit pixels comprises a shallow trench isolation (STI) pattern that defines at least one or more active areas within the unit pixel.
