Patent ID: 7282408

Claim:
A method for forming a semiconductor device, comprising: providing an oxide layer as part of a semiconductor wafer substrate assembly; placing the semiconductor wafer substrate assembly into a deposition chamber; flowing a silicon-containing gas selected from the group consisting of SiH 4 , Si 2 H 6 , and methylated silanes into the deposition chamber for a duration of between about 0.1 milliseconds and about 10 seconds to expose the oxide layer to the silicon-containing gas; subsequent to exposing the oxide layer to the silicon-containing gas, flowing a ruthenium metal precursor into the deposition chamber to form a ruthenium metal layer on the oxide layer; purging the ruthenium metal precursor from the chamber for between about 1 second and about 60 seconds; then repeating the flow of the ruthenium metal precursor into the deposition chamber and the purging of the ruthenium metal precursor from the chamber a sufficient number of times to form the ruthenium metal layer of a sufficient thickness.
