    Abstract: The invention relates to a deep insulating trench, comprising side walls (11) and a base (10), embodied in a semiconductor substrate (1). The side walls (11) and the base (10) are coated with an electrically insulating material (12) which defines an empty cavity (13) and forms a plug (14) to seal the cavity (13). The side walls (11) are embodied with a neck (15) for determining the position of the plug (15) and a first section (16) which tapers out towards the neck (15) with increasing separation from the base (10). The above is particularly suitable for application in bipolar circuits and BiCMOS.

    Abstract: The production of an integrated circuit incorporating an insulating gaseous layer totally separating at least two selected tracks of a level of metallization of row i (Mi) comprises: (a) realizing the metallization of row I by inserting a sacrificial material (MSi) between the selected tracks at this level; (b) realizing, in the material of the insulating inter-tracks (IMDi+1) separating the tracks of the level of metallization of row i+1 and in the inter-way insulating material (ILDi+1) separating the interconnection contacts at the level of interconnection of row I+1, some shafts (CH) emerging in the sacrificial material; and (c) eliminating the sacrificial material across these shafts. An Independent claim is also included for an integrated circuit incorporating an insulating gaseous layer totally separating at least two tracks of a level of metallization of the circuit (L1, L2).

    IPC: H01L21/02

    Abstract: The fabrication of a metal plate capacitor in the metallisation levels above an integrated circuit consists of depositing an insulating layer (11) of between 0.5 and 1.5 microns on the surface of an integrated circuit (10). Method then involves grooving the insulating layer to form slabs (12), depositing and smoothing a metallic material (14) to form conducting lines (L1, L2, L3, L4) in the slabs, locally drawing the insulating layer to eliminate all the gaps separating two conducting lines, depositing a dielectric layer (16) and depositing and engraving a second metallic material (17) to at least completely fill the inter-line gaps.

    Abstract: An integrated circuit capacitor includes a substrate, a first metal electrode on the substrate, and a dielectric layer on the first metal electrode. The dielectric layer includes a homogeneous combination of at least two dielectric materials having permittivities varying in an opposite way based upon an electric field, with a proportion of each dielectric material being chosen so that the integrated circuit capacitor has a desired voltage linearity. A second metal electrode is on the dielectric layer.
