Patent ID: 7557047

Claim:
A method of forming a layer of material by performing an atomic layer deposition (ALD) process in a process chamber of a process tool, the method comprising: positioning a substrate within said process chamber; establishing a ligand removal environment in said chamber; and performing an ALD process comprised of a plurality of first pulsing patterns to form a first portion of a layer of material above said substrate and a plurality of second pulsing patterns to form a second portion of the layer of material above said substrate, each of said first and second pulsing patterns comprising: evacuating said chamber during a first time period; introducing a precursor gas into said chamber during a second time period; and evacuating said chamber during a third time period; wherein said second time period during said first plurality of pulsing patterns is different from said second time period during said second plurality of pulsing patterns, and wherein the first portion of the layer and the second portion of the layer differ in at least characteristic selected from the group consisting of degree of crystallinity and resistivity.
