Patent ID: 7919409

Claim:
A method for controlling agglomeration and improving adhesion of a semiconductor device comprising: a. providing a substrate comprising at least one patterned dielectric layer and at least one barrier layer; b. depositing an adhesion promoting layer comprising a chromium alloy on the at least one barrier layer; and c. depositing a metal seed layer on the adhesion promoting layer; wherein adhesion energy between the adhesion promoting layer and the barrier layer is higher than adhesion energy between the adhesion promoting layer and the metal seed layer; wherein the chromium alloy is deposited from a chromium containing precursor having complexes of a polydentate β-ketoiminate selected from the group consisting of structure A, and structure B; wherein: R 1 is a branched bulky alkyl group containing 1 to 6 carbon atoms; R 2 is selected from the group consisting of hydrogen, alkyl having from 1 to 6 carbon atoms, alkoxy having from 1 to 6 carbon atoms, cycloaliphatic having from 3 to 6 carbon atoms, and aryl having from 6 to 10 carbon atoms; R 3-4 are linear or branched selected from the group consisting of alkyl having from 1 to 6 carbon atoms, alkoxy having from 1 to 6 carbon atoms, cycloaliphatic having from 3 to 6 carbon atoms, and aryl having from 6 to 10 carbon atoms; R 5-6 are linear or branched, individually selected from the group consisting of linear alkyl having from 1 to 6 carbon atoms, fluoroalkyl having from 1 to 6 carbon atoms, cycloaliphatic having from 3 to 10 carbon atoms, aryl having from 6 to 10 carbon atoms, and heterocyclic containing either oxygen, or nitrogen atoms; L is monodentate donor ligand.
