Patent ID: 7838084

Claim:
An atomic layer deposition method of depositing an oxide on a substrate comprising: chemisorbing a first species onto a substrate to form a first species monolayer onto the substrate from a gaseous precursor, the first species monolayer being at least substantially saturated; contacting the chemisorbed first species with an oxygen plasma derived at least in part from at least one of O 2 and O 3 and generated remote from the substrate, and with a plasma nitrogen generated remote from the substrate, effective to react with the first species to form a monolayer that is at least substantially saturated and comprises an oxide of a component of the first species monolayer, the remote plasma oxygen and the remote plasma nitrogen being generated in different remote plasma generating chambers; and successively repeating the chemisorbing and the contacting with remote plasma oxygen and with remote plasma nitrogen effective to form porous oxide on the substrate.
