IMAGE SENSOR INCLUDING NANO-PHOTONIC MICROLENS ARRAY AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18216014 titled 'IMAGE SENSOR INCLUDING NANO-PHOTONIC MICROLENS ARRAY AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor that includes a sensor substrate with pixels for sensing incident light, and a nano-photonic microlens array that faces the light incident surface of the sensor substrate. The microlens array condenses the incident light using nano-photonic microlenses. Each pixel includes photosensitive cells arranged in two directions to independently sense the incident light, and an isolation for electrically isolating the photosensitive cells. The nano-photonic microlenses have a convex phase profile and are arranged in a two-dimensional array in a diagonal direction.
