Abstract: Composant microélectronique, réalisé à partir d'un substrat de type silicium sur isolant totalement appauvri (FDSOI), comportant une couche d'oxyde (102) séparant deux couches de silicium, à savoir une couche mince (103) et une couche épaisse (101), comportant une première zone active (110), formée par une fraction (104) de la couche mince reliée à au moins deux zones de connexion distinctes (115, 116), et comportant une seconde zone active (150), formée par une fraction (120) de la couche épaisse (101), reliée à au moins deux zones de connexion distinctes (126, 124), ladite fraction (120) de la couche épaisse étant située à l'aplomb de ladite fraction (104) de la couche mince.

Abstract: The invention concerns a method wherein the formation of low doped zones (NLDD 17, 61) of the second transistor (T2) with fine oxide comprises an implantation of a first doping agent (16) having a first concentration and an implantation of a second doping agent (22) having a second concentration lower than the first concentration. The formation of low doped zones (NLDD 61) of the first transistor (T1) with thick oxide comprises only said implantation of the second doping agent (22).

Abstract: A method of simultaneously fabricating a pair of insulated gate transistors respectively having a thin oxide and a thick oxide, and an integrated circuit including a pair of transistors of this kind. Forming low-doped NLDD areas of the thin oxide second transistor includes implanting a first dopant having a first concentration and implanting a second dopant having a second concentration lower than the first concentration. Forming low-doped areas NLDD of the first, thick oxide transistor includes only said implantation of the second dopant.
