This paper presents the plasma-enhanced atomic layer deposition (PEALD) of titanium nitride (TiN) using the organic precursor tetrakis(ethylmethylamido)titanium (TEMAT), with remote ammonia (NH3) plasma as reactant gas. This work investigates the impact of substrate temperature, from 150-350°C, and plasma times, from 5-30s, on deposition rate, resistivity, carbon content, N/Ti ratio and film density. The lowest resistivity of ~ 250 μΩ.cm was achieved at substrate temperatures 300-350°C and plasma time of 20s. At low substrate temperatures, although deposition was possible, carbon concentration was found to be higher, which thus affects film resistivity and density.
