Patent ID: 8283201

Claim:
A method for depositing a lanthanide-containing film on a semiconductor substrate, the method comprising: a) providing a substrate; b) providing the lanthanide-containing precursor of the general formula: Ln(R 1 C p ) m (R 2 —N—C(R 4 )═N—R 2 ) n , wherein: Ln is a lanthanide metal having an ionic radius from approximately 0.75 Å to approximately 0.94 Å, a 3+ charge, and a coordination number of 6; R 1 is selected from the group consisting of H and a C1-C5 alkyl chain; R 2 is selected from the group consisting of H and a C1-C5 alkyl chain; R 4 is selected from the group consisting of H and Me; n and m range from 1 to 2; and c) depositing a lanthanide-containing film on the substrate.
