摘要：

The structure and electrical properties of cobalt nitride (CoNX) thin films, prepared by newly developed r.f. reactive sputtering with magnetically enhanced ionization by means of multipolar magnetic plasma confinement (MMPC), were studied. In an unbalanced magnetron sputtering system with MMPC, ferromagnetic materials can be sputtered at a low gas pressure (8.0 x 10(-2) Pa). It was found that lowering the total gas pressure (Ar + N-2) down to 8.0 x 10(-2) Pa resulted in a decrease in the resistivity of the films, whose value is about 10 mu Omega cm. The average size of the grain decreased with a decrease in the total gas pressure. Nanocomposite films of cobalt nitride with an average grain size of about 5 nm were formed by lowering the total gas pressure. (C) 2001 Elsevier Science Ltd. All rights reserved.
