  • Patent number: 12209105
    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.

  • Publication number: 20240395895
    Abstract: Provided are carbon-free (i.e., less than about 0.1 atomic percentage of carbon) Zr doped HfO2 films, where Zr can be up to the same level of Hf in terms of atomic percentage (i.e., 1% to 60%). The Zr doping can be achieved also by nanometer m laminated ZrO2 and HfO2 films useful in ferroelectric memories (FeRAM). The laminated films are comprised of about 5 to 10 layers of HfO2 and ZrO2 (i.e., alternating) films, each of which for example can be a thickness of about 1 to about 2 nm, wherein the laminated films are a total of about 5 to 10 nm in thickness.

  • Patent number: 12037681
    Abstract: Provided is a method for forming a silicon oxycarbonitride film (SiOCN) with varying proportions of each element, using a disilane precursor under vapor deposition conditions, wherein the percent carbon incorporation into the SiOCN film may be varied between about 5 to about 60%, by utilizing co-reactants chosen from oxygen, ammonia, and nitrous oxide gas. The carbon-enriched SiOCN films thus formed may be converted to pure silicon dioxide films after an etch stop protocol by treatment with O2 plasma.

  • Patent number: 11987878
    Abstract: Chemical vapor deposition (CVD) processes which use a ruthenium precursor of formula R1R2Ru(0), wherein R1 is an aryl group-containing ligand, and R2 is a diene group-containing ligand and a reducing gas a described. The CVD can include oxygen after an initial deposition period using the ruthenium precursor and reducing gas. The method can provide selective Ru deposition on conductive materials while minimizing deposition on non-conductive or less conductive materials. Further, the subsequent use of oxygen can significantly improve deposition rate while minimizing or eliminating oxidative damage of the substrate material. The method can be used to form Ru-containing layers on integrated circuits and other microelectronic devices.

  • 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.
