    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.
