Patent ID: 7776733

Claim:
A method for processing a substrate, the method comprising: providing a substrate in a process chamber; heating the substrate to a temperature of 250° C. or greater; performing a sequential deposition cycle in a chemical vapor deposition (CVD) process, whereby a TiN film with a thickness greater than 1 atomic layer and less than 1 nm is deposited in each cycle by sequentially, in any order: exposing the substrate to a process gas containing tetrakis(ethylmethylamino) titanium (TEMAT) precursor vapor and an inert carrier gas, wherein the TEMAT precursor thermally decomposes at the substrate, and exposing the substrate to a nitrogen precursor without a titanium precursor vapor, wherein the nitrogen precursor is plasma-excited and is selected from N 2 , NH 3 , N(CH 3 ) 2 , N(C 2 H 5 ) 2 , N 2 H 4 , or a C 1 -C 10 hydrazine compound; and repeating the exposing steps until the TiN film has a predetermined total thickness.
