Patent attributes
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.
