Patent ID: 7833913

Claim:
A method of processing a substrate, comprising: disposing the substrate in a process chamber; and exposing the substrate to a gas pulse sequence to deposit a doped hafnium zirconium based film with a predetermined thickness, wherein the gas pulse sequence includes, in any order: a) sequentially first, exposing the substrate to a gas pulse comprising a hafnium precursor, and second, exposing the substrate to a gas pulse comprising an oxygen-containing gas, a nitrogen-containing gas, or an oxygen- and nitrogen-containing gas; b) sequentially first, exposing the substrate to a gas pulse comprising a zirconium precursor, and second, exposing the substrate to a gas pulse comprising the oxygen-containing gas, the nitrogen-containing gas, or the oxygen- and nitrogen-containing gas; c) sequentially first, exposing the substrate to a gas pulse comprising one or more dopant elements selected from Group II, Group XIII, silicon, and rare earth elements of the Periodic Table, and second, exposing the substrate to a gas pulse comprising the oxygen-containing gas, the nitrogen-containing gas, or the oxygen- and nitrogen-containing gas, wherein each of a), b), and c) are alternatingly performed or concurrently performed, any number of desired times to achieve the predetermined thickness; and d) annealing the substrate, wherein a doped hafnium zirconium oxide film is formed with a stable cubic or tetragonal form that survives the annealing.
