Abstract:
1. A process comprising the steps of: i) placing a sputter target having a target surface in a vacuum chamber; ii) placing a substrate having a substrate surface in a vacuum chamber; iii) reducing the pressure in the vacuum chamber to about 100 Torr or less; iv) removing atoms from the surface of the sputter target while the sputter target is in the vacuum chamber at a pressure of about 100 Torr or less, wherein the step of removing atoms from the surface of the sputter target employs a magnetic field and/or an electric field; and v) depositing atoms on the surface of the substrate so that a molybdenum containing layer is formed, wherein the molybdenum containing layer includes an alloy having about 50 atomic % or more molybdenum 0.1 to 45 atomic % titanium; and 0.1 to 45 atomic % of a third metal element, based on the total number of atoms in the sputter target, wherein the third metal element is tantalum or chromium; wherein the molybdenum containing layer has a thickness of about 200 nm or less.
