Tris(diethylamido)(tert-butylimido)tantalum(V) was involved as a precursor in the atomic layer deposition of films, including a new route for selective deposition of thin oxide by atomic layer deposition. Plasma-enhanced ALD (PE-ALD) is considered to be very promising for the deposition of high-quality, stable, and conductive tantalum-based films. The reactants for the thALD TaxNy barrier layer deposition at 250 °C were TBTDET as precursor and ammonia as co-reactant. A novel plasma-enhanced atomic layer deposition-grown mixed-phase/nanolaminate Ru–TaN barrier has been investigated, and it was confirmed that the copper diffusion barrier and direct-plate characteristics of the mixed-phase barrier can be modulated by varying the metal ratio in the film.
