Abstract

Liquid precursor material of a coating substance and a solvent is provided in a reservoir (STEP1, STEP1′). In one variant the liquid precursor material is distilled (STEP2), the resultant liquid coating substance is vaporized (STEP3) and ejected through a vapor distribution nozzle arrangement (7) into a vacuum recipient (3) and onto substrate 5 to be coated. Alternatively, the liquid precursor material is directly vaporized (STEP3′). From the two-component vapor coating substance vapor is applied to substrate 5′ to be coated. In this variant separation of solvent vapor and coating substance vapor is performed especially downstream vaporizing (STEP2′).
