Process for depositing tungsten or other refractory metals on semiconductor devices by a reaction of a gas containing the metal in a vapor deposition reactor. The reaction occurs at relatively low temperature (240 DEG -400 DEG C.) and pressure (0.1-10 torr), and the resulting film adheres differently to different substrate materials. Patterned coatings can be made without the patterning steps which are required with prior art techniques.
