Claim Text:
1. A method for making a microelectronic device including the steps as consisting of: a) making one or several semiconducting bars, designed to form at least one transistor channel or several transistor channels of a first type in a first region of a thin semiconducting layer of a substrate facing an opening in a first mask, said substrate being a semiconductor on insulator type substrate comprising a support layer on which an insulating layer is supported, said thin semiconducting layer being supported on said insulating layer; b) removing an area from the insulating layer in extension of said opening in said first mask so as to expose said semiconducting bars; and c) replacing said area removed from said insulating layer by a given dielectric material with a composition and a thickness selected to facilitate capacitive coupling between said support layer and said conducting bars.
