Claim Text:
1. An image sensor comprising: a pixel array comprising: wherein each of the at least two focusing pixels comprises: a semiconductor layer including a photodetecting device accumulating electric charges generated according to absorbed light from among the incident light; a wiring layer on a first surface of the semiconductor layer and including wirings; a planarization layer on a second surface of the semiconductor layer and having a first surface; a shielding layer in the planarization layer to block a portion of the incident light to be received by the photodetecting device; and a color filter layer and a micro lens layer on a second surface of the planarization layer that is opposite the first surface of the planarization layer, wherein the color filter layer is configured to selectively transmit the incident light according to a wavelength of the incident light and the micro lens layer is configured to selectively focus the incident light onto the photodetecting device, and wherein the shielding layer is in the planarization layer in contact with the first surface of the planarization layer or the second surface of the planarization layer.
