Abstract
A process and apparatus for LPCVD of thin metallic films is disclosed. The apparatus includes a U-shaped injection tube through which high molecular weight reactants are injected into a reaction chamber. The input and output ends of the U-shaped tube are coupled to a removeable feedthrough plate which, in turn, is coupled to the end cap which seals one end of the reaction chamber. A deposition surface is placed in the chamber through a second end cap at the opposite end of the chamber. The output end of the U-shaped injection tube is coupled to a vacuum pump and the high molecular weight reactant is drawn through the injection tube and dispersed in the reaction chamber through a plurality of holes in the input side of the injection tube.
