Abstract: L'invention concerne un procédé de réalisation d'un capteur d'images (31) à éclairement par la face arrière à partir d'un substrat semiconducteur (33), ce procédé comportant les étapes suivantes : a) former, depuis la face avant du substrat, des zones (38) de même type de conductivité que le substrat mais de niveau de dopage supérieur, s'étendant en profondeur sous ladite face avant, ces zones étant bordées de régions isolantes (35) orthogonales à la face avant ; b) amincir le substrat par la face arrière jusqu'à proximité desdites zones et jusqu'à atteindre les régions isolantes ; c) évider partiellement les régions isolantes du côté de la face arrière ; et d) recuire superficiellement, par laser, la face arrière du substrat.

Abstract: L'invention concerne un procédé de fabrication d'un circuit intégré contenant des transistors MOS complètement et partiellement déplétés, comprenant les étapes suivantes .a) former des transistors MOS similaires sur une couche mince de silicium (3) formée sur une couche de silicium-germanium (2) reposant sur un substrat de silicium ;b) coller la face supérieure de la structure à une plaquette support (21) ;c) éliminer le substrat;d) déposer un masque (23) et ouvrir ce masque aux emplacements des transistors complètement déplétés ;e) oxyder le silicium-germanium aux emplacements des transistors complètement déplétés dans des conditions telles qu'il se produit un phénomène de condensation ; etf) éliminer la partie oxydée et la partie de silicium-germanium, d'où il résulte qu'il demeure des transistors dont la couche de silicium est amincie.

Abstract: When the fabrication of the insulated gate field effect transistor is started, then the bipolar transistor (BIP1,BIP2) is totally fabricated, before the resumption of fabrication of the insulated gate field effect transistor (MOS), and the step of common finishing of the two transistors is executed, including the common thermal reheating treatment (122) and common silication treatment.

Abstract: The production of connections buried in an integrated circuit comprises: (a) providing a structure made up of a first support slice stuck in the rear surface of a thin semiconductor slice, one or more integrated circuit elements possibly being realised in or above the thin slice; (b) sticking a second support slice on the structure at the side of the leading surface of the thin slice; (c) eliminating the first support slice; (d) forming some connections between the different zones of the rear surface of the thin slice; (e) sticking a third support slice on the connections; and (f) eliminating the second support slice. An Independent claim is also included for an integrated circuit incorporating some components and produced by the above process.

Abstract: Prior to the implementation of transistors, one configures within the substrate a deep insulated drain following the configuration within the substrate of a less deep insulated drain lengthening the deep drain. The configuration of the deep drain includes a coating of the internal walls of the drain by an initial layer of oxide (100) obtained by a rapid thermal oxidation and a filling of the drain with polysilicon (120) inside an envelope formed with an insulating material (101). The configuration of the less deep drain also includes a coating of the internal walls with an initial oxide layer (15) obtained by rapid thermal oxidation and a filling with an insulating material (16, 17). An Independent claim is also included for an integrated circuit incorporating within a substrate some insulating deep drain and less deep drain regions separating the transistors.

Abstract: Production of a metal-metal capacitor within an IC is carried out by forming the two metal electrodes (40, 71) and the dielectric layer (61) on the lower insulating layer (2) bearing a metallisation level (M1) of the IC before depositing the upper insulating layer (80) for covering the metallisation level (M1). Also claimed is an IC including a metal-metal capacitor (40, 61, 71) produced as described above. Preferably, the first capacitor electrode (40) is part of the metallisation level (preferably aluminium), the second electrode (70, 71) is a thinner layer preferably of aluminium or tungsten and the dielectric layer (61) is a thin SiO2, Si3N4 or Ta2O5 layer.
