More Information
Summary:A device which can be exposed to chemical vapors, such as a molybdenum vapor, a tungsten vapor, or any combination thereof, which has a coating covering at least a portion thereof. The coating reduces or inhibits mass change at an outer surface of the device from exposure to the vapor. In certain situations, the mass change is a mass gain, and the coating reduces or inhibits the mass gain of equal to or less than 1×10−5 g mm−2.
