  • Publication number: 20240096631
    Abstract: The present disclosure relates to a bridging asymmetric haloalkynyl dicobalt hexacarbonyl precursors, and ultra high purity versions thereof, methods of making, and methods of using these bridging asymmetric haloalkynyl dicobalt hexacarbonyl precursors in a vapor deposition process. One aspect of the disclosure relates to an ultrahigh purity bridging asymmetric haloalkynyl dicobalt hexacarbonyl precursor of the formula Co2(CO)6(R3C?CR4), where R3 and R4 are different organic moieties and R4 is more electronegative or more electron withdrawing compared to R3.

  • Publication number: 20220364225
    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.
