1. A semiconductor apparatus, comprising:

  • a substrate having a substrate surface;

    a layer of a first material overlying a first region of said substrate surface;

    a layer of a semiconductor overlying said layer of first material and overlying a second region of said substrate surface;

    a first region of said layer of semiconductor, overlying said layer of first material and having a first conductivity;

    a second region of said layer of semiconductor, overlying said second region of said substrate surface and having a second conductivity; and

    said first conductivity being substantially different from said second conductivity.
