Abstract
Integrated circuits and methods of producing integrated circuits are provided. In an exemplary embodiment, an integrated circuit includes a source and a drain defined within a body isolation well. A gate overlies the body isolation well between the source and the drain, and an isolating structure is formed within the body isolation well. The isolating structure sections the source into a plurality of source sections with the plurality of source sections adjacent to one gate.
