Abstract
A mist is generated by a venturi from liquid precursors containing compounds used in chemical vapor deposition, transported in carrier gas through tubing at ambient temperature, passed into a heated zone where the mist droplets are gasified at a temperature of between 100.degree. C. and 200.degree. C., which is lower than the decomposition temperature of the precursor compounds. The gasified liquid is injected through an inlet assembly into a deposition reactor in which there is a substrate heated to from 400.degree. C. to 600.degree. C., on which the gasified compounds decompose and form a thin film of layered superlattice compound.
