Patent ID: 7709402

Claim:
A method comprising: forming a first nanolaminate on a substrate, the nanolaminate containing a first plurality of different insulating materials including a first layer of hafnium silicon oxynitride (Hf x Si y O z N r with x>0, y>0, z>0, and r>0), the first layer of hafnium silicon oxynitride formed using a self-limiting monolayer or partial monolayer sequencing process; forming a layer of titanium nitride by the self-limiting monolayer or partial monolayer sequencing process on the first layer of hafnium silicon oxynitride; forming a second nanolaminate on the substrate, the second nanolaminate containing a second plurality of different insulating materials including a second layer of hafnium silicon oxynitride (Wf k Si l O m N n with k>0, l>0, m>0, and n>0), the second layer of hafnium silicon oxynitride formed on the substrate using the self-limiting monolayer or partial monolayer sequencing process, the second layer of hafnium silicon oxynitride processed such that the second layer of hafnium silicon oxynitride is separate from the first layer of hafnium silicon oxynitride; and forming a layer of tantalum by the self-limiting monolayer or partial monolayer sequencing process on the second layer of hafnium silicon oxynitride.
