Abstract

PURPOSE:To protect the surface of a film for forming pattern by intermittently supplying protective films to the surface of the film for forming pattern by means which supplies the protective films whenever exposure operations are performed for the required number of times. CONSTITUTION:A protective film supplying means E which supplies protective films 10 which protect the surface of a film 1 for forming pattern and updates the previous protective film whenever exposure operations are performed by an exposure device for a required number of times for forming patterns on a substrate 3 is provided. This means E is constituted of a feeding roll 7, take-up roll 8, and tension roll 9. Namely, the protective film 10 is set while covering the film 1 for forming pattern from the feeding roll 7 to the take-up roll 8. Since the tension roll 9 is set so as to push the film 10 upward, no winkle is produced on an exposure glass plate 5. Therefore, damages of the protective films 10 can be minimized.

As described above, according to this embodiment, the protective film!
By means (E) in which the protective film 10 is made into a strip and is supplied by a roll 7.8 and removed by a, the protective film 10 and the pattern forming film 1 can be separated, and the exposure operation can always be carried out using a new protective film 10. Therefore, it is suitable for pattern formation on a substrate 3 with a high p degree, and it is also suitable for forming a pattern on a substrate 3 with a high p degree.
This has the effect of suppressing the occurrence of a large number of successive identical defects caused by failure of 0 I11 or the like.
