Abstract
An exemplary image sensor includes a micro lens arranged in a horizontal direction and a vertical direction, neighboring lenses in the horizontal direction and the vertical direction in the micro lens array without having a gap, and a gap between the neighboring lenses in a diagonal direction.
Claims20
An image sensor, comprising an array of micro lenses and a plurality of gaps, wherein the array of micro lenses has a horizontal direction a vertical direction, neighboring lenses in the horizontal direction and the vertical direction have a zero gap therebetween, and the gaps are between neighboring lenses in a diagonal direction.
An image sensor, comprising:
- a lower structure having a plurality of photodiodes and a wiring;
- and
- a micro lens array on the lower structure having a horizontal direction a vertical direction, each micro lens being configured to focus light on a corresponding photodiode,
- wherein neighboring lenses in the horizontal direction and the vertical direction have a zero gap therebetween, and a gap or space is between neighboring lenses in a diagonal direction.
A method of fabricating an image sensor comprising:
- forming a patterned photoresist array having in a horizontal direction and a vertical direction;
- and
- forming a micro lens array in the horizontal direction and the vertical direction by thermally processing the patterned photoresist array, wherein neighboring lenses in the horizontal direction and the vertical direction have a zero gap therebetween, and neighboring lenses in a diagonal direction have a gap or space therebetween.
