Abstract: An aerothermodynamic separator for a refrigerated display cabinet is disclosed. The separator comprises a flat member having a predetermined dimension defining a shape of the separator. The separator is adapted to be removably positioned between a front end of one or more shelves associated with the cabinet and a rear end of a connecting region between two adjacent doors of the cabinet. The separator is adapted to restrict infiltration of outside air in a conservation space behind the doors of the cabinet upon opening at least one of the doors.

Abstract: A method of processing a substrate that includes: loading the substrate in a plasma processing chamber, the substrate having a surface including an oxide, the oxide including an alkaline earth metal; flowing a process gas including CCl4 into the plasma processing chamber; in the plasma processing chamber, forming a fluorine-free plasma from the process gas by applying a source power to a source electrode of the plasma processing chamber; and exposing the substrate to the fluorine-free plasma to etch the oxide of the surface.

Abstract: A method for producing a layer covering the first surfaces of a structure and leaving the second surfaces uncovered including a sequence for forming an initial layer by PEALD deposition, the sequence including cycles, each including injections of first and second precursor in a reaction chamber, and plasma formation in the reaction chamber. The cycles are carried out at a temperature Tcycle such that Tcycle ? (Tmin - 20° C.), Tmin being the minimum temperature of a nominal temperature window for a PEALD deposition. The method includes exposing the initial layer to a densification plasma such that the exposure to the ion flow makes the material on the first surfaces more resistant to etching than the material on the second surfaces. The method also includes a selective etching step, such that the initial layer covers the first surfaces of the front face of the structure by leaving the second surfaces uncovered.

Abstract: A method of etching a metal includes performing at least two cycles of an etch process. A cycle of the etch process includes: performing a surface modification on an exposed surface of a metal layer over a substrate, performing a hydrogen treatment on the metal layer, and performing a cleaning treatment on the metal layer. The hydrogen treatment forms a layer of reaction products on the metal layer. The cleaning treatment removes the layer of reaction products.

Abstract: A method for forming spacers on a gate pattern includes deposition of a first dielectric layer having basal portions on an active layer and side portions of the edges of the pattern; anisotropic modification of only the basal portions of the first layer, so as to obtain modified basal portions; deposition of a second dielectric layer on the first layer, also having basal and side portions; anisotropic etching of only the basal portions of the second layer, so as to remove these basal portions while conserving the side portions; and removal of the modified basal portions while conserving the first and second non-modified side portions, by selective etching of the modified dielectric material vis-à-vis the non-modified dielectric material.

Abstract: The invention relates to a process for transformation of lignocellulosic biomass or cellulose using in a simultaneous manner an original combination of at least two homogeneous catalysts and one or more heterogeneous catalyst(s). The use of these catalysts makes it possible to obtain mono-oxidized or poly-oxidized upgradable products directly and to limit the formation of non-upgradable products. Non-upgradable products are defined as soluble and non-soluble humins, i.e., products of high molecular weight obtained from undesirable condensation reactions of sugars and their derivatives.
