Abstract:
1. A precursor delivery system for delivering pulses of vaporized precursor material to a reaction space in a thin film deposition system, comprising: a precursor container for holding a supply of precursor material; a flow path from the precursor container to the reaction space; a pulse control device interposed between the precursor container and the reaction space, the pulse control device adapted to selectively release pulses of the precursor material toward the reaction space via the flow path; and a high conductivity particle filter interposed in the flow path between the precursor container and the reaction space, the high conductivity particle filter including at least one inertial trap adjacent the flow path for filtering particles from the precursor material without significantly restricting flow of the pulses through the flow path.
