    摘要: The present invention relates to an enhanced sequential atomic layer deposition (ALD) technique suitable for deposition of barrier layers, adhesion layers, seed layers, low dielectric constant (low-k) films, high dielectric constant (high-k) films, and other conductive, semi-conductive, and non-conductive films. This is accomplished by 1) providing a non-thermal or non-pyrolytic means of triggering the deposition reaction; 2) providing a means of depositing a purer film of higher density at lower temperatures; and, 3) providing a faster and more efficient means of modulating the deposition sequence and hence the overall process rate resulting in an improved deposition method.

    摘要: A system and method for that allows one part of an atomic layer deposition (ALD) process sequence to occur at a first temperature while allowing another part of the ALD process sequence to occur at a second temperature. In such a fashion, the first temperature can be chosen to be lower such that decomposition or desorption of the adsorbed first reactant does not occur, and the second temperature can be chosen to be higher such that comparably greater deposition rate and film purity can be achieved. Additionally, the invention relates to improved temperature control in ALD to switch between these two thermal states in rapid succession.
