Title:
A spatial light modulator, an exposure device, and a device manufacturing method
Document Type and Number:
Japanese Patent JP5991601
Kind Code:
B2
Abstract:
A spatial light modulator includes a first reflective surface which reflects incident light and is movable between a first position and a second position, the first and the second positions being located along a first axis, a second reflective surface which reflects the incident light, is arranged at a position where the second reflective surface is adjacent to the first reflective surface in a direction along a second axis crossing the first axis, and is movable between a third position and a fourth position, the third and the fourth positions being located along a direction parallel to the first axis, and a reflective part which reflects the incident light and is arranged between the first reflective surface and the second reflective surface in the direction along the second axis, wherein a distance between the first position and the reflective part, defined in the direction parallel to the first axis, is configured to attenuate light reflected at the reflective part by using light reflected at the first reflective surface, and a distance between the second position and the reflective part, defined in the direction parallel to the first axis, is configured to attenuate the light reflected at the reflective part by using the light reflected at the first reflective surface.
