Abstract
An image sensor includes a light receiving element, an anti-reflection layer, a high refractive pattern, a color filter, and a micro lens. The light receiving element is formed on a semiconductor substrate to generate charges responsive to incident light. The anti-reflection layer is formed on the semiconductor substrate. The high refractive pattern is formed on the anti-reflection layer in correspondence with the light receiving element. The color filter is formed on the anti-reflection layer while covering a top surface and lateral sides of the high refractive pattern. The micro lens is formed on the color filter. The image sensor provides an image having high quality.
Claims20
A unit pixel of an image sensor, the unit pixel comprising:
- a light receiving element formed on a semiconductor substrate and configured to generate charges responsive to incident light;
- a first high refractive pattern formed on the light receiving element without being shared by an adjacent unit pixel, the first high refractive pattern allowing the incident light to pass therethrough;
- and
- a color filter formed on all of a top surface and all of lateral sides of the first high refractive pattern.
An image sensor comprising:
- a plurality of unit pixels, each of the plurality of unit pixels comprising:
- a light receiving element formed on a semiconductor substrate and configured to generate charges responsive to incident light;
- a first high refractive pattern formed on the light receiving element without being shared by an adjacent unit pixel, the first high refractive pattern allowing the incident light to pass therethrough;
- and
- a color filter formed on all of a top surface and all of lateral sides of the first high refractive pattern.
A system comprising:
- an image sensor, the image sensor comprising a plurality of unit pixels, each of the plurality of unit pixels comprising:
- a light receiving element formed on a semiconductor substrate and configured to generate charges responsive to incident light;
- a first high refractive pattern formed on the light receiving element without being shared by an adjacent unit pixel, the first high refractive pattern allowing the incident light to pass therethrough;
- and
- a color filter formed on all of a top surface and all of lateral sides of the first high refractive pattern.
