Patent ID: 8017182

Claim:
A method for depositing a multi-component thin film on a substrate in a reaction chamber, the method comprising: performing a plurality of deposition cycles, each cycle comprising: depositing a first component of the film on the substrate by flowing a first and second reactant into the reaction chamber in sequential and alternating pulses during a period A, the first and second reactants depositing self-limitedly on the substrate, wherein the first component is an oxide; and depositing a second component of the film by flowing a third reactant into the reaction chamber while simultaneously flowing a fourth reactant into the reaction chamber during a period B, wherein the third and fourth reactants are mutually reactive, wherein a total exposure time of the substrate to the fourth reactant during the period B is longer than a total exposure time of the substrate to the third reactant during the period B, and wherein the second component is a nitride.
