EVAPORATION SOURCE FOR DEPOSITION OF EVAPORATED MATERIAL ON A SUBSTRATE, DEPOSITION APPARATUS, METHOD FOR MEASURING A VAPOR PRESSURE OF EVAPORATED MATERIAL, AND METHOD FOR DETERMINING AN EVAPORATION RATE OF AN EVAPORATED MATERIAL

Abstract:

An evaporation source for deposition of evaporated material on a substrate is described. The evaporation source including a crucible for material evaporation; a distribution assembly with one or more outlets for providing the evaporated material to the substrate, the distribution assembly being in fluid communication with the crucible; and a measurement assembly. The measurement assembly includes a tube connecting an interior space of the distribution assembly with a pressure sensor.
