There are two possible ways to produce metal alloys in our reactors. The chosen method depends on the alloy’s chemical composition and number of elements.

• The first solution is the best known but least versatile. It involves working from composite targets that are often used in industry for clearly identified and recurring needs.
• We prefer to use the second solution: co-sputtering of pure targets. This enables us to overcome the problem of synthesis of composite targets, often impossible without thermodynamic equilibrium. Not only that, this technique allows us to explore a vast range of compositions during the coating development process. This method is the best compromise during the research and development phase.
