Abstract:
A method of forming a ruthenium seed layer on a substrate comprising the steps of:(a) vaporizing a ruthenium-containing compound; (b) introducing the vaporized ruthenium-containing compound into a CVD apparatus; (c) introducing oxygen into the CVD apparatus to form an oxygen rich environment; wherein said oxygen is introduced at a flow rate of about 1000 sccm to about 5000 sccm; (d) maintaining the oxygen rich environment in a process chamber of the CVD apparatus; (e) depositing a ruthenium oxide layer onto the substrate by chemical vapor deposition; and (f) annealing the deposited ruthenium oxide layer in a gas ambient to remove oxygen from said ruthenium oxide layer thus forming the ruthenium seed layer.
