    Abstract: The invention relates to a method for depositing a carbon material (17) in or on a substrate (14). Said method comprises the following steps: the inside (10') of a processing chamber (10) is heated to a pre-determined temperature; the substrate (14) is introduced into the processing chamber (10); the air in the processing chamber (10) is evacuated until a pre-determined pressure or a lower pressure is reached; a gas (12) containing at least carbon is introduced until a second pre-determined pressure is reached, that is higher than the first pre-determined pressure; and the carbon material (17) is deposited on a surface or in a recess (15), from the gas (12) containing carbon. The invention also relates to a semiconductor contact device.

    Abstract: A method for reducing polymer deposition on vertical surfaces of metal lines etched from a metallization layer disposed above a substrate. The method includes forming a hard mask layer above the metallization layer and providing a photoresist mask above the hard mask layer. The method further includes employing the photoresist mask to form a hard mask from the hard mask layer. The hard mask has patterns therein configured to form the metal lines in a subsequent plasma-enhanced metallization etch. There is also included removing the photoresist mask. Additionally, there is included performing the plasma-enhanced metallization etch employing the hard mask and an etchant source gas that includes Cl2 and at least one passivation-forming chemical, wherein the plasma-enhanced metallization etch is performed without employing photoresist to reduce the polymer deposition during the plasma-enhanced metallization etch.

    Abstract: A method for forming a plurality of electrically conductive wires on a substrate. The method includes forming a relatively non-planar metal layer over a surface of the substrate. A self-planarizing material is deposited over the metal layer. The self-planarizing material forms a planarization layer over the surface of the metal layer. The planarization layer has a surface relatively planar compared to the relatively non-planar metal layer. A photoresist layer is deposited over the surface of the planarization layer. The photoresist layer is patterned with a plurality of grooves to form a mask with such grooves exposing underling portions of the planarization layer. The photoresist mask is used as a mask to etch grooves in the exposed portions of the planarization layer and thereby form a second mask. The second mask exposes underling portions of the relatively non-planar metal layer. The second mask is used to etch grooves in the relatively non-planar conductive metal layer and thereby form the plurality of electrically conductive wires in the metal layer. The wires are separated from each other by the grooves formed in the relatively non-planar metal layer. The planarization layer is formed by a spinning-on an organic polymer, for example an organic polymer having silicon, or a flowable oxide, or a hydrogensilsequioxane, or divinyl-siloxane-benzocyclobutene. The metal layer is etched using reactive ion etching. The planarization layer is removed using a wet chemical etch.

    Abstract: A nonvolatile integrated semiconductor memory has an arrangement of layers with a tunnel barrier layer and a charge-storing level. The charge-storing level has a dielectric material which stores scattered in charge carriers in a spatially fixed position. The tunnel barrier layer has a material through which high-energy charge carriers can tunnel. At least one interface surface of the charge-storing level has a greater microscopic roughness than the interface surface of the tunnel barrier layer, which is remote from the charge-storing level. The charge-storing level has a greater layer thickness in first regions than in second regions. This produces a relatively identical distribution and localization of positive and negative charge carriers in the lateral direction. The charge carriers which are scattered into the charge-storing level, therefore, recombine completely, so that the risk of unforeseen data loss during long-term operation of nonvolatile memories is reduced.
