Patent ID: 8133528

Claim:
An electron gun evaporation apparatus including, in a vacuum chamber configured to be evacuated, an electron gun configured to irradiate an electron beam to an evaporation source and to form a film on a substrate by evaporating the evaporation source by heat of the irradiated electron beam, and electron beam position control means which has a memory and controls said electron gun so as to irradiate the electron beam to a predetermined position of the evaporation source, wherein said electron beam position control means (i) stores, in the memory, information concerning an irradiation position of the electron beam and information concerning a film thickness growth rate corresponding to the irradiation position before the electron gun irradiates the electron beam and the evaporation source is evaporated, and (ii) controls, based on the information stored in the memory, the electron gun so as to irradiate the electron beam for forming the film on the substrate in a range within which a distribution of the film thickness growth rate is substantially constant in a scanning direction of the electron beam.
