Abstract

A method and apparatus are disclosed for forming thin films of chemical compounds utilized in integrated circuits. The method includes steps of forming a precursor liquid comprising a chemical compound in a solvent, providing a substrate within a vacuum deposition chamber, producing a mist of the precursor liquid, and flowing the mist into the deposition chamber while maintaining the chamber at ambient temperature to deposit a layer of the precursor liquid on the substrate. The liquid is dried to form a thin film of a solid material on the substrate, then the integrated circuit is completed to include at least a portion of the film of solid material in a component of the integrated circuit.
