Abstract:
1. A diaphragm valve for a thin film deposition system, comprising: a valve body defining a valve passage having an inlet and an outlet; a valve seat adjacent the valve passage; a flexible diaphragm having first and second sides, the diaphragm positioned adjacent the valve passage opposite the valve seat with the first side facing toward the valve seat, the diaphragm operable in response to an applied actuation force to flex between an open position whereby the valve passage is at least partially open and a closed position whereby a portion of the first side of the diaphragm is pressed against the valve seat to thereby block the valve passage and facilitate heat transfer between the valve seat and the diaphragm; and a heating body thermally contacting the valve body and extending proximal to the second side of the diaphragm, thereby forming a thermally conductive pathway from the valve body to proximal of the second side of the diaphragm that facilitates maintaining an operating temperature at the diaphragm.
