1. A method of depositing a sacrificial Silicon nitride layer on a substrate, the method comprising:

  • introducing a vapor of SiH2I(N(iPr)2) and/or SiH2I(N(iBu)2) into a reactor having a substrate disposed therein and depositing at least part of SiH2I(N(iPr)2) and/or SiH2I(N(iBu)2) onto the substrate;

    introducing a nitrogen-containing reactant into the reactor to form the sacrificial silicon nitride layer at a rate ranging from approximately 0.5 Å

    /cycle to approximately 1 Å

    /cycle using a vapor deposition method; and

    removing the sacrificial silicon nitride layer at a rate of approximately 102 Å

    /minute.
