Abstract: PURPOSE:To execute the processing of a uniform exposure quantity by a simple device by dividing a processing object to be exposed having a large area into several blocks and exposing them successively so that an integrating exposure quantity of each exposure partition becomes equal. CONSTITUTION:A filter 7 is divided into plural partitions 9-1, 9-2,...9-n and exposed. That is, when transmittivity of light of the filter 7 is assumed as 100% in the center part (a), transmittivity in the pherical part (b) in which film thickness of a Cr vapor-deposited film increases is lowered, and the film thickness is set in advance so as to show a roughly trapezoid-like transmission characteristic. At the time of exposing a work 9, by projecting a light beam, while executing a scan continuously so that each partition (9-1, 9-2,...9-n) to be exposed is overlapped to each other, the peripheral parts (b) of adjacent partitions (9-1, 9-k, 9-k-1,...) are overlapped to each other and exposed. Accordingly, the film thickness of the vapor-deposited film of the peripheral part (b) is set so that an integrating exposure quantity brought on by a double exposure becomes equal to an exposure quantity of the center part (a). In such a way, at the time of exposing a large area, a uniform exposure can be executed by using an inexpensive and simple device.
