    摘要: A precursor delivery system includes a flow path from a precursor container to a reaction space of a thin film deposition system, such as an atomic layer deposition (ALD) reactor. At least a portion of the flow path may be formed in one or more blocks of thermally conductive material forming an elongate thermally conductive body extending from the precursor container toward the reaction space. In some embodiments, a heater is thermally associated with the thermally conductive body to inhibit condensation of precursor vapor in the flow path. A high conductivity particle filter having inertial traps is preferably included for filtering particles from the precursor material. The particle filter preferably include a filter passage including turns and inertial traps adjacent the turns. In some embodiments, the filter passage and the inertial traps may be formed in the thermally conductive body between the precursor container and the reaction space.

    摘要: A precursor delivery system includes a flow path from a precursor container to a reaction space of a thin film deposition system, such as an atomic layer deposition (ALD) reactor. A staging volume is preferably established between the precursor container and the reaction space for receiving at least one dose of the precursor material from the precursor container, from which a series of pulses is released toward the reaction space. The precursor material is typically vaporized after loading it in the precursor container by heating or reducing the pressure inside the precursor container. A vacuum line is preferably coupled to the precursor container and bypasses the reaction space for reducing pressure inside the precursor container without drawing particles into the reaction space. A high conductivity particle filter having inertial traps may be included, preferably between the precursor container and a staging volume, for filtering particles from the precursor material.
