Abstract:
1. A method of manufacturing an evaporation source for physical vapor deposition, the evaporation source having a target with a given thermal conductivity, and a backing plate connected to the target and consisting of a material having a better thermal conductivity than the target, the method which comprises: providing a target material in powdery form, the target material having an aluminum component with a given melting point and at least one additional component with a given melting point; providing a backing plate material in powdery form; layering the target material in powdery form and the backing plate material each in powdery form into layered powder fractions; and commonly cold-pressing the target material and the backing plate material from the layered powder fractions and subsequent deforming at temperatures below the melting points of the individual components of the materials while flowing until a density of at least 98% of a theoretical density is achieved, to thereby form a compact of the evaporation source having a target and a backing plate connected to the target.
