摘要:
A method for conducting an ALD process to deposit layers on a substrate which includes an electrostatic chuck (ESC) to retain the substrate. Electrode(s) in the chuck assembly are used to induce a voltage on the substrate to promote precursor adsorption on the substrate.
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 deposition system includes a process chamber for conducting an ALD process to deposit layers on a substrate. An electrostatic chuck (ESC) retains the substrate. A backside gas increases thermal coupling between the substrate and the ESC. The ESC is cooled via a coolant flowing through a coolant plate and heated via a resistive heater. Various arrangements are disclosed.

摘要:
A deposition system includes a process chamber for conducting an ALD process to deposit layers on a substrate. In one embodiment, instead of varying the gas flux on a substrate in the chamber by controlling the flow of gas upstream of the process chamber, the gas flux on the substrate is controlled by controlling the conductance between the process chamber and a lower pressure volume outside the process chamber. The flux of the gas on the substrate varies inversely with the chamber conductance, such that the flux of the gas on the substrate increases when the conductance decreases. Various methods of performing an ALD process by controlling the conductance are disclosed as well as various structures for controlling the conductance.
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.
