An image sensor including a substrate, a trench isolation, a plurality of image sensing units, at least one phase detection unit, and an interconnection layer is provided. The trench isolation is in the substrate, and a plurality of active areas of the substrate are separated from each other by the trench isolation. The image sensing units and the at least one phase detection unit are in the active areas arranged in an array, and a sensing area of the at least one phase detection unit is smaller than a sensing area of each of the image sensing units. The interconnection layer is disposed on the image sensing units and the at least one phase detection unit. In addition, a method of fabricating an image sensor is also provided.
