Methods for forming work function layers (e.g., titanium nitride work function layers) for transistors are described. The methods energizing a process gas disposed in an inner volume of a processing chamber to create a plasma, and pulsing the process gas between a poison regime and a metallic regime using a fast response mass flow controller to deposit the work function layer on the substrate surface.
