An image sensor that has a pixel array formed on a semiconductor substrate is disclosed. The pixel array may also be formed on an epitaxial layer formed on the said semiconductor substrate. A plurality of pixels are arranged in a pattern and formed on the epitaxial layer or directly on the semiconductor substrate. Further, a deep trench isolation formed in the semiconductor substrate, and used to separate adjacent pixels of the plurality of pixels. The deep trench isolation extends through substantially the entire epitaxial layer.
