1. A pixel array of an image sensor, comprising:

  • a first color pixel formed on a substrate and configured to sense light of a first optical spectrum;

    a panchromatic pixel formed on the substrate and configured to sense light of a second optical spectrum; and

    a planarization layer formed on the first color pixel and panchromatic pixel, wherein;

    the panchromatic pixel and the planarization layer have an integrated structure which is formed in a same process using a planarization material; and

    a range of the second optical spectrum is larger than a range of the first optical spectrum.
