  • Publication number: 20240140819
    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.

  • Patent number: 11965239
    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 ? to about 15 ? and less than about 1% of void area. Once such nucleation has been achieved, traditional layer-upon-layer deposition can rapidly take place.

  • Publication number: 20230041086
    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.
