Zusammenfassung:	Embodiments of the invention provide an improved apparatus and methods for nitridation of stacks of materials. In one embodiment, a remote plasma system includes a remote plasma chamber defining a first region for generating a plasma comprising ions and radicals, a process chamber defining a second region for processing a semiconductor device, the process chamber comprising an inlet port formed in a sidewall of the process chamber, the inlet port being in fluid communication with the second region, and a delivery member disposed between the remote plasma chamber and the process chamber and having a passageway in fluid communication with the first region and the inlet port, wherein the delivery member is configured such that a longitudinal axis of the passageway intersects at an angle of about 20 degrees to about 80 degrees with respect to a longitudinal axis of the inlet port.
