PLASMA-ENHANCED MOLYBDENUM DEPOSITION

Embodiments of the disclosure are directed to methods of depositing a molybdenum film directly on a substrate surface (e.g., a low-K dielectric material) by exposing the substrate surface to a molybdenum-containing precursor and a plasma at a temperature of less than or equal to 400° C. The molybden...

Zusammenfassung:Embodiments of the disclosure are directed to methods of depositing a molybdenum film directly on a substrate surface (e.g., a low-K dielectric material) by exposing the substrate surface to a molybdenum-containing precursor and a plasma at a temperature of less than or equal to 400° C. The molybdenum-containing precursor comprises one or more of molybdenum pentachloride (MoCl5), molybdenum dioxide dichloride (MoO2Cl2), molybdenum oxytetrachloride (MoOCl4), molybdenum hexacarbonyl, bis(tert-butylimido)-bis(dimethylamido)molybdenum, or bis(ethylbenzene) molybdenum. The plasma comprises one or more of hydrogen (H2), nitrogen (N2), or a silane (SixHy). In some embodiments, when the molybdenum-containing precursor comprises molybdenum hexafluoride (MoF6), the plasma does not include hydrogen (H2).
