Plasma excitation for spatial atomic layer deposition (ALD) reactors
Abstract:
A spatial atomic layer deposition (ALD) system is disclosed. The system includes a chamber that includes a plurality of zones oriented along a track. Also included is a shuttle that is configured to support the substrate and transport the substrate to each of the plurality of zones to enable deposition of a thin film. The shuttle includes an RF power electrode and an RF ground electrode coupled to an RF power source. The RF electrode and the RF ground electrode are each embedded in the shuttle, such that power provided by the RF power source to the shuttle moves with the shuttle to each of the zones. The RF power source is configured to be activated in synchronization with moving the shuttle to one of the zones.
