  • Patent number: 11189486
    Abstract: A method for depositing a layer of a material onto a substrate, comprising: one gas-phase injection of a first chemical species with a precursor of such insulating material, into a deposition chamber of a chemical vapor deposition reactor, through a first injection path, according to a first pulse sequence; one gas-phase injection of a second chemical species with a reactant adapted to react with such precursor, into the deposition chamber, through a second injection path, according to a second pulse sequence which is phase-shifted relative to the first pulse sequence; one sequential generation of a plasma of the first chemical species and/or the second chemical species during at least one pulse of at least one of the first and second sequences, with such plasma being generated from a high frequency (HF) plasma source and a low frequency (LF) plasma source applied to the first and second injection paths, the low frequency (LF) plasma source power on the high frequency (HF) plasma source power ratio being abov

  • Patent number: 11114340
    Abstract: The invention relates to a method for producing an interconnection comprising a via (V) extending through a substrate (1), said method successively comprising: (a) the deposition of a layer (11) of titanium nitride or tantalum nitride on a main surface (1A) of the substrate and on the inner surface (10A, 10B) of at least one hole (10) extending into at least part of the thickness of said substrate; (b) the deposition of a layer (12) of copper on said layer (11) of titanium nitride or tantalum nitride; and (c) the filling of the hole (10) with copper, said method being characterized in that, during step (a), the substrate (1) is arranged in a first deposition chamber (100), and in that said step (a) comprises the injection of a titanium or tantalum precursor in a gaseous phase into the deposition chamber via a first injection path according to a first pulse sequence, and the injection of a nitrogen-containing reactive gas into the deposition chamber via a second injection path different from the first injectio

  • Publication number: 20180327907
    Abstract: The present invention relates to a method for producing a layer (2) of aluminum oxide and/or aluminum nitride (Al2O3, or AIN) on a substrate (1), said method comprising a sequence of consecutive steps a) and b) according to which: a) a basic layer of aluminum (21, 22) having a thickness between 5 and 25 nm is deposited on the substrate (1) in a deposition chamber (10), b) the substrate (1) is moved into a treatment chamber (20) separate from the deposition chamber (10), in which the basic layer of aluminum (21, 22) is oxidized or nitrided to produce a basic layer of aluminum oxide or aluminum nitride (21? 22?). Said sequence of consecutive steps is repeated in a loop until said layer of aluminum oxide and/or aluminum nitride (2) is obtained by stacking the consecutive layers of aluminum oxide and aluminum nitride (21? 22?).
