    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 shut-off type diaphragm valve adapted for use in an atomic layer deposition system includes a flexible diaphragm operable to flex between an open position whereby a valve passage is at least partially open and a closed position whereby a substantial portion of a first side of the diaphragm is pressed against a valve seat to thereby block the valve passage and facilitate heat transfer between the valve seat and the diaphragm. In some embodiments, a heating body thermally contacts the valve body and extends proximal to a second side of the diaphragm opposite the first side thereof to form a thermally conductive pathway that facilitates maintaining an operating temperature at the diaphragm. A thermally resistive member may be interposed between the valve passage and an actuator, such as a solenoid, for attenuating heat transfer between the valve passage and the actuator.

    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.

    摘要： A shut-off type diaphragm valve adapted for use in an atomic layer deposition system includes a valve seat having an annular seating surface that surrounds an inlet of the valve and extends radially therefrom. The seating surface contacts a substantial portion of the first side of a flexible diaphragm when the diaphragm is closed, to facilitate heat transfer and counteract dissipative cooling of the diaphragm, thereby inhibiting condensation of a medium flowing through the valve passage. The seating surface is preferably flat and smooth, to prevent shearing of an elastomeric diaphragm. For a plastic diaphragm, a ring-shaped seating ridge may extend from the seating surface to cause localized permanent deformation of the diaphragm and enhanced sealing, while still allowing a substantial portion of the diaphragm to contact the seating surface for enhanced heat transfer. Valve speed enhancements and other reliability enhancing features are also described.

    摘要： A diaphragm valve includes a heating body that thermally contacts a valve body of the valve and extends proximal to a diaphragm of the valve opposite a valve passage through which medium flows. The heating body forms a thermally conductive pathway between the valve body and the diaphragm that facilitates maintaining an operating temperature at the diaphragm. When used in an atomic layer deposition (ALD) system, the diaphragm valve inhibits condensation or freezing of high-temperature ALD precursor gases in the valve passage. A plunger including thermally insulating features preferably extends through a central opening in the heating body to operably couple a valve actuator to the diaphragm. In some embodiments, a thermally resistive member may be interposed between the valve passage and the actuator for attenuating heat transfer between the valve passage and the actuator.
