Abstract:
A method of enhanced atomic layer deposition is described. In an embodiment, the enhancement is the use of plasma. Plasma begins prior to flowing a second precursor into the chamber. The second precursor reacts with a prior precursor to deposit a layer on the substrate. In an embodiment, the layer includes at least one element from each of the first and second precursors. In an embodiment, the layer is TaN. In an embodiment, the precursors are TaF5 and NH3. In an embodiment, the plasma begins during the purge gas flow between the pulse of first precursor and the pulse of second precursor. In an embodiment, the enhancement is thermal energy. In an embodiment, the thermal energy is greater than generally accepted for ALD (>300 degrees Celsius). The enhancement assists the reaction of the precursors to deposit a layer on a substrate.
