Abstract:
1. A method for depositing at least one layer containing at least one first component on at least one substrate in a process chamber, wherein first and second starting materials are introduced in gaseous form in alternation cyclically into the process chamber, the first starting material comprises two β-diketones and one diene coordinated with a ruthenium atom, the first starting material of which contains the first component and the second starting material of which contains reactive oxygen, said method characterized in that simultaneously with or at some time after the first starting material is introduced into the process chamber, a limiter A is introduced into the process under chamber process parameters in which the first component cannot be deposited by self-limiting deposition in a single layer on the substrate, wherein the limiter A contains at least one of the following substances: octane, butyl acetates, tetrahydrofuran, methanol, ethanol, isobutylamines, triethylamines, butanol and cyclohexane; thereafter keeping the process parameters the same except for replacing the limiter A by a different limiter B thereby to deposit the first component in a single layer in a self-limiting deposition fashion, wherein the limiter B contains at least one of the following substances: isooctane, dioxane, dimethylformamide, pyridine and toluene.
