    Abstract: Provided is a plasma enhanced atomic layer deposition (PEALD) process for depositing etch-resistant SiOCN films. These films provide improved growth rate, improved step coverage and excellent etch resistance to wet etchants and post-deposition plasma treatments containing O2 and NH3 co-reactants. This PEALD process relies on one or more precursors reacting in tandem with the plasma exposure to deposit the etch-resistant thin-films of SiOCN. The films display excellent resistance to wet etching with dilute aqueous HF solutions, both after deposition and after post-deposition plasma treatment(s). Accordingly, these films are expected to display excellent stability towards post-deposition fabrication steps utilized during device manufacturing and build.

    Abstract: Selective ruthenium deposition and related systems and methods are provided. A method comprises vaporizing at least a portion of a ruthenium precursor to produce a vaporized ruthenium precursor; contacting a first surface portion and a second surface portion of a substrate with the vaporized ruthenium precursor and at least one reducing gas; and depositing ruthenium on the first surface portion of the substrate with a selectivity of at least 25 Å relative to the second surface portion of the substrate. A device comprises a substrate having a first surface portion and a second surface portion adjacent to the first surface portion; and a ruthenium layer located on the first surface portion of the substrate, wherein the ruthenium layer has a thickness of at least 25 Å on the first surface portion of the substrate; wherein the second surface portion of the substrate does not comprise ruthenium.

    Abstract: Provided is improved methodology for the nucleation of certain metal nitride substrate surfaces utilizing certain silicon-containing halides, silicon-containing amides, and certain metal precursors, in conjunction with nitrogen-containing reducing gases. While utilizing a pretreatment step, the methodology shows greatly improved nucleation wherein a microelectronic device substrate having such a metal nitride film deposited thereon has a thickness of about 10 Å to about 15 Å and less than about 1% of void area. Once such nucleation has been achieved, traditional layer-upon-layer deposition can rapidly take place.

    Abstract: The invention provides a process for preparing molybdenum and tungsten oxyhalide compounds which are useful in the deposition of molybdenum and tungsten containing films on various surfaces of microelectronic devices. In the process of the invention, a molybdenum or tungsten trioxide is heated in either a solid state medium or in a melt-phase reaction comprising a eutectic blend comprising alkaline and/or alkaline earth metal salts. The molybdenum or tungsten oxyhalides thus formed may be isolated as a vapor and crystallized to provide highly pure precursor compounds such as MoO2Cl2.

    Abstract: A deposited cobalt composition is described, including cobalt and one or more alloy component that is effective in combination with cobalt to enhance adhesion to a substrate when exposed on the substrate to variable temperature and/or delaminative force conditions, as compared to corresponding elemental cobalt, wherein the one or more alloy component is selected from the group consisting of boron, phosphorous, tin, antimony, indium, and gold. Such deposited cobalt composition may be employed for metallization in semiconductor devices and device precursor structures, flat-panel displays, and solar panels, and provides highly adherent metallization when the metallized substrate is subjected to thermal cycling and/or chemical mechanical planarization operations in the manufacturing of the semiconductor, flat-panel display, or solar panel product.
