    Abstract: An integrated semiconductor structure (500) comprises two homologous P-type regions (120 and 130) formed within an N-type epitaxial layer (110). A P-type region (510) formed in the portion of the epitaxial layer (110) disposed between the two P-type regions (120 and 130) includes within it an N-type region (520); this N region (520) is electrically connected to the P region (130) by means of a surface metal contact (530). The structure reduces the injection of current between the P region 120 and the P region 130, at the same time preventing any vertical parasitic transistors from being switched on.
