    Abstract: An integrated circuit incorporates a buried layer of the type with conductivity determined in a plane essentially parallel to a plane of a main surface of the circuit. The median part of this buried layer (23, 24) is filled with a metallic type material (29). An Independent claim is also included for a method for the formation of a layer buried in a semiconductor substrate of an integrated circuit.

    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.
