Abstract:
1. A projecting exposure apparatus, comprising: i) spatial light modulation means provided with a plurality of pixel sections arrayed in two-dimensional directions, which pixel sections modulate incident light in accordance with a predetermined control signal, the spatial light modulation means performing spatial light modulation of the light with the plurality of the pixel sections, ii) an image-side telecentric image forming optical system for forming an image of a two-dimensional pattern of the light, which has been obtained from the spatial light modulation performed by the spatial light modulation means, and iii) a microlens array located in the vicinity of a plane of image formation of the two-dimensional pattern, whose image is formed by the image-side telecentric image forming optical system, the microlens array being provided with a plurality of microlenses arrayed in two-dimensional directions, each of which microlenses transmits one of light beams corresponding respectively to the pixel sections of the spatial light modulation means and having passed through the image-side telecentric image forming optical system, the two-dimensional pattern of the light being projected onto the photosensitive material, the photosensitive material being thus exposed to the two-dimensional pattern of the light, wherein the projecting exposure apparatus further comprises a magnification adjusting optical system, which is located between the image-side telecentric image forming optical system and the microlens array, and which adjusts a magnification of image formation at the time of the formation of the image of the two-dimensional pattern of the light with the image-side telecentric image forming optical system.
