  • Patent number: 10526701
    Abstract: Methods of depositing uniform films on substrates using multi-cyclic atomic layer deposition techniques are described. Methods involve varying one or more parameter values from cycle to cycle to tailor the deposition profile. For example, some methods involve repeating a first ALD cycle using a first carrier gas flow rate during precursor exposure and a second ALD cycle using a second carrier gas flow rate during precursor exposure. Some methods involve repeating a first ALD cycle using a first duration of precursor exposure and a second ALD cycle using a second duration of precursor exposure.

  • Patent number: 10480067
    Abstract: A film deposition method for filling a recessed pattern with a SiN film is provided. NH2 groups are caused to adsorb on a surface of a substrate containing a recessed pattern formed in a top surface of the substrate by supplying a first process gas containing NH3 converted to first plasma to the surface of the substrate containing the recessed pattern. The NH2 groups is partially converted to N groups by supplying a second process gas containing N2 converted to second plasma to the surface of the substrate containing the recessed pattern on which the NH2 groups is adsorbed. A silicon-containing gas is caused to adsorb on the NH2 groups by supplying the silicon-containing gas to the surface of the substrate containing the recessed pattern on which the NH2 groups and the N groups are adsorbed. The above steps are cyclically repeated.
