1. A method for depositing a film on a substrate that is within a reaction chamber, the method comprising applying an atomic layer deposition cycle to the substrate, the cycle comprising:
exposing the substrate to a precursor gas for a precursor pulse interval and then removing the precursor gas; and exposing the substrate to an oxidizer comprising an oxidant gas and a nitrogen-containing species gas comprising activated ionic or radical species for an oxidation pulse interval and then removing the oxidizer; prior to introducing the nitrogen-containing species to the reaction chamber, monitoring the nitrogen-containing species; and adjusting one or more process parameters based on the step of monitoring. |
