Patent ID: 7892964

Claim:
A method of forming a metal-containing layer on a substrate, the method comprising: providing a vapor comprising at least one titanium precursor compound; providing a vapor comprising at least one metal-organic strontium precursor compound; and contacting the vapor comprising the at least one titanium precursor compound and the vapor comprising the at least one strontium precursor compound with a substrate to form SrTiO 3 -containing material on at least one surface of the substrate using an atomic layer deposition process comprising multiple atomic layer deposition cycles, wherein the multiple deposition cycles sequentially comprise: an initial titanium oxide deposition phase comprising an initial plurality of titanium oxide atomic layer deposition cycles; an intermediate deposition phase comprising an intermediate plurality of strontium oxide atomic layer deposition cycles and an intermediate plurality of titanium oxide atomic layer deposition cycles, the intermediate plurality of titanium oxide atomic layer deposition cycles being greater in number than the intermediate plurality of strontium oxide atomic layer deposition cycles and resulting in the intermediate deposition phase to comprise SrTiO 3 having strontium:titanium atomic ratio of from 0.9:1.0 to 1.0:0.9; and a final titanium oxide deposition phase comprising a final plurality of titanium oxide atomic layer deposition cycles.
