1. A photosensitive imager device, comprising:

  • a semiconductor substrate having a substantially planar surface and multiple doped regions forming a least one junction;

    a textured region coupled to the semiconductor substrate on a surface opposite the substantially planar surface and positioned to interact with electromagnetic radiation;

    integrated circuitry formed at the substantially planar surface; and

    an electrical transfer element coupled to the semiconductor substrate and operable to transfer an electrical signal from the at least one junction.
