Abstract

PURPOSE:To form films of patterns having stable film quality by disposing a target film provided with a film forming material in a vacuumed hermetic vessel, irradiating the film with a laser beam from the outside and relatively scanning the beam according to the prescribed patterns. CONSTITUTION:The target film 17 constituted by forming the film forming material 19 on one surface of a light transparent base film 18 is disposed in the hermetic vessel 15 subjected to a pressure reduction by a pressure reducing means 24. Further, a substrate 23 is disposed in proximity to the above- mentioned film forming material 19. The laser beam 13 from a laser oscillator 12 is focuses by a lens 14 and is introduced through a light transparent part 19 into the hermetic vessel 15. This introduced laser beam 13 is cast through the base film 18 to the film forming material 19. This irradiation is executed to the unirradiated part by moving the target film 17 via winding cores 20, 21. The above-mentioned substrate 23 is then moved via an X-Y table 22 and the laser beam 13 is relatively scanned according to the prescribed patterns. The patterns of the stable and good film quality are directly plotted on the substrate 23 in this way.
