Abstract: Le procédé comporte successivement la réalisation, sur un substrat (1), d'un empilement de couches (2, 3) comportant au moins une première couche (3) en composé de germanium et silicium ayant initialement une concentration de germanium comprise entre 10 et 50%. La première couche (3) est disposée entre des secondes couches (2) ayant des concentrations de germanium comprises entre 0 et 10%. Ensuite, on délimite par gravure, dans ledit empilement, une première zone (5) correspondant à l'élément à base de germanium et ayant au moins une première dimension latérale comprise entre 10nm et 500nm. Puis est effectuée une oxydation thermique, au moins latérale, de la première zone (5), de manière à ce qu'une couche de silice (6) se forme à la surface de la première zone (5) et en ce que, dans la première couche (3), une zone centrale (8) de germanium condensé se forme, constituant l'élément à base de germanium.

Abstract: The invention relates to a process for making a copper connection with a copper connection element in an integrated circuit comprising a damascene structure, with the connection element being covered successively with an encapsulation layer and at least one layer of dielectric material with a very low dielectric constant. The process includes the steps of etching the layer of dielectric material until the encapsulation layer is reached in order to obtain a connection hole opposite the connection element. A protective layer is then formed on the walls of the connection hole, with the protective layer preventing contamination of the dielectric layer from diffusion of copper. The protective and encapsulation layers are then etched at the bottom of the connection hole in such a way as to reveal the connection element. The connection hole is then filled with copper.

Abstract: A MOS transistor formed in a silicon substrate (101) comprises: (a) an active zone (100) surrounded by an insulating partition (102); (b) a first conducting strip (103) covering a central strip of the active zone; (c) one or more second conducting strips (105, 106, 107) placed in the active zone plumb with the first strip; (d) some conducting regions (108, 109) placed in two cavities in the insulating partition and joined to the ends of the first and second strips; (e) the surfaces of the silicon opposite the strips and conducting regions are covered with an insulator (130) constituting an oxide grid. An independent claim is also included for the production of this MOS transistor.

Abstract: The capacitor manufacture method for several levels of metallization has a step of formation at an inter track isolating level (3) two electrodes (50, 70) and a dielectric layer (60) with a conductor slice (51). At the upper track level (8) two conductor pads (80, 87) are formed contacting the upper electrode and the conductor slice.

Abstract: Le substrat (1) est muni d'une première zone semiconductrice (2) recouverte partiellement par un premier motif de grille (3) pour définir une surface protégée (2b) et une surface ouverte (2a). Une couche continue de silicium-germanium (6) est déposée de manière non sélective sur la première zone semiconductrice (2) et sur le premier motif de grille (3). La couche continue de silicium-germanium (6) forme une interface avec la première zone semiconductrice (2). Un recuit de diffusion/condensation est réalisé pour faire diffuser les atomes de germanium depuis la couche de silicium-germanium (6) vers la surface ouverte de la première zone semiconductrice (2).

Abstract: A method produces a microstructure comprising an island of material confined between two electrodes forming barriers, the island ( 30 ) of material having lateral flanks running parallel to and lateral flanks running perpendicular to the barriers, wherein the lateral flanks of the island are defined by etching of at least one layer ( 16 ), called the template layer, and the barriers are formed by damascening. The method includes (a) a first etching of the template layer using a first etching mask having at least one filiform part, and (b) a second etching of the template layer, subsequent to the first etching, using a second etching mask also having at least one filiform part, oriented in a direction forming a non-zero angle with a direction of orientation of the filiform part of the first mask, in the vicinity of the site of formation of the island.
