COMPOSANT, PAR EXEMPLE TRANSISTOR NMOS, A REGION ACTIVE A CONTRAINTES EN COMPRESSION RELACHEES, ET PROCEDE DE FABRICATION

摘要

An integrated circuit includes a substrate and at least one NMOS transistor having, in the substrate, an active region surrounded by an insulating region. The insulating region is formed to includes at least one area in which the insulating region has two insulating extents that are mutually separated from each other by a separation region formed by a part of the substrate.
