Patent ID: 7393783

Claim:
A method of forming a metal-containing structure, comprising: providing a substrate; and performing at least one iteration of the following sequence: exposing a surface of the substrate to a first reactant comprising a metal other than aluminum bonded to halogen atoms to form a first layer over the substrate; the first layer comprising the metal together with halogen atoms from the reactant; removing the first reactant from proximity to the substrate surface; exposing the first layer to trialkylaluminum to remove the halogen atoms from the first layer and convert the first layer to a first material consisting of the metal; removing the trialkylaluminum from proximity to the first layer; exposing the first material to the first reactant to form a second layer comprising the metal together with halogen atoms from the reactant over and in direct physical contact with the first material; and exposing the second layer to trialkylaluminum to convert the second layer to a second material consisting of the metal.
