Abstract

A process for coating a substrate at atmospheric pressure comprises the steps of vaporizing a controlled mass of semiconductor material at substantially atmospheric pressure within a heated inert gas stream, to create a fluid mixture having a temperature above the condensation temperature of the semiconductor material, directing the fluid mixture at substantially atmospheric pressure onto the substrate having a temperature below the condensation temperature of the semiconductor material, and depositing a layer of the semiconductor material onto a surface of the substrate.
