Abstract: An integrated circuit includes a substrate having at least one first domain and at least one second domain that is different from the at least one first domain. A trap-rich region is provided in the substrate at the locations of the at least one second domain only. Locations of the at least one first domain do not include the trap-rich region.

Abstract: A silicon on insulator substrate includes a semiconductor bulk handle wafer, an insulating layer on said semiconductor bulk handle wafer and a semiconductor film on said insulating layer. An opening extends completely through the semiconductor film and insulating layer to expose a surface of the semiconductor bulk handle wafer. Epitaxial material fills the opening and extends on said semiconductor film, with the epitaxial material and semiconductor film forming a thick semiconductor film. A trench isolation surrounds a region of the thick semiconductor film to define an electrical contact made to the semiconductor bulk handle wafer through the opening.
