Abstract: A region of monocrystalline silicon (20, 124 - 128) on insulator on silicon (24, 120) is destined to receive at least one component. The insulator (26) comprises some over-thickness (OT). Independent claims are also included for: (a) a component realised in such a region of monocrystalline silicon; (b) the fabrication of a semiconductor on insulator region; (c) the fabrication of a MOS transistor.

Abstract: Metal contacts are self-positioned on a wafer of semiconductor product. Respective placement areas for a metal contact are determined by a selective deposition of a growth material over a region of the substrate surface (for example, through epitaxial growth). The growth material is surrounded by an insulating material. The grown material is then removed to form a void in the insulating material which coincides with the desired location of the metal contact. This removal of the grown material exposes the region on the substrate surface. Conductive material is then deposited to fill the void and thus form the metal contact directly with the region of the substrate surface.

Abstract: The unit has a pair of cells (C1, C2) for storing two independent bits and including field effect transistors with grid (4, 14), respectively. A channel is arranged in a source zone (102), and the two transistors are arranged in between the source zone and a drain zone. An electrode of single polarization (24) is arranged between intermediate portions (1, 11) of the two transistors. An independent claim is also included for a method for manufacturing an integrated DRAM on a surface of a substrate.

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: A method for forming in monolithic form a DRAM-type memory, including the steps of forming, on a substrate, parallel strips including a lower insulating layer, a strongly-conductive layer, a single-crystal semiconductor layer, and an upper insulating layer; digging, perpendicularly to the strips, into the upper insulating layer and into a portion of the semiconductor layer, first and second parallel trenches, each first and second trench being shared by neighboring cells; forming, in each first trench, a first conductive line according to the strip width; forming, in each second trench, two second distinct parallel conductive lines, insulated from the peripheral layers; filling the first and second trenches with an insulating material; removing the remaining portions of the upper insulating layer; and depositing a conductive layer.
