A method of depositing a metal or other desired material onto a substrate using a gas generated via the sublimation of solid material precursors, wherein a sold precursor is introduced into a liquid in a bubbler apparatus so that the bubbler then contains vapors of solid precursor, and then sweeping a carrier gas through the bubbler to a reactor containing a substrate which is coated with the precursor via chemical vapor deposition.

Delivery systems for gases for gases via the sublimation of solid precursors

A method of producing a smooth surface for a film of refractory metallic material is realized by placing a substrate in a CVD reactor; initiating deposition of a layer of two phase material via concurrent introduction into the CVD reactor of a precursor gas and molecular oxygen, the latter at a pressure between about 1.times.10.sup.-6 and 1.times.10.sup.-4 ; and annealing the treated layer at the deposition temperature.
