Patent ID: 7250380

Claim:
A method of depositing a silicon dioxide-comprising layer in the fabrication of integrated circuitry, comprising: flowing an aluminum-containing organic precursor to a chamber containing a first semiconductor substrate effective to deposit an aluminum-comprising layer over the first substrate; flowing an alkoxysilanol to the first substrate comprising the aluminum-comprising layer within the chamber effective to deposit a silicon dioxide-comprising layer over the first substrate; after the deposit, cleaning the chamber with at least one halogen-containing species; after the cleaning, providing at least one of activated oxygen, activated nitrogen, and activated hydrogen within the chamber effective to react with residual halogen present within the chamber from the cleaning; after the providing, flowing an aluminum-containing organic precursor to the chamber containing a second semiconductor substrate effective to deposit an aluminum-comprising layer over the second substrate; flowing an alkoxysilanol to the second substrate comprising the aluminum-comprising layer within the chamber effective to deposit a silicon dioxide-comprising layer over the second substrate; and the reacting of the at least one of activated oxygen, the activated nitrogen, and the activated hydrogen being effective to increase growth rate of the silicon dioxide-comprising layer over the second substrate than would otherwise occur under identical conditions in the absence of such prior reacting.
