  • Patent number: 12359309
    Abstract: Provided is a process for the vapor deposition of molybdenum or tungsten, and the use of molybdenum hexacarbonyl (Mo(CO)6) or tungsten hexacarbonyl (W(CO)6) for such deposition, e.g., in the manufacture of semiconductor devices in which molybdenum-containing or tungsten-containing films are desired. In accordance with one aspect of the invention, molybdenum hexacarbonyl (Mo(CO)6) has been found in vapor deposition processes such as chemical vapor deposition (CVD) to provide low resistivity, high deposition rate films in conjunction with a pulsed deposition process in which a step involving a brief pulse of H2O is utilized. This pulsing with H2O vapor was found to be effective in reducing the carbon content of films produced from Mo(CO)6-based CVD processes.

  • 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.
