Abstract:
A method for inspecting a spatial light modulator includes: performing such control that in an inspection target area in an array of mirror elements, the mirror elements in a first state in which incident light is given a phase change amount of 0 and the mirror elements in a second state in which incident light is given a phase change amount of 180° (π) become arrayed in a checkered pattern; guiding light having passed the inspection target area to a projection optical system with a resolution limit coarser than a width of an image of one mirror element, to form a spatial image; and inspecting a characteristic of the spatial light modulator from the spatial image. This method allows us to readily perform the inspection of the characteristic of the spatial light modulator having the array of optical elements.

Claim (Index 33):
The exposure method according to  claim 29 , wherein each of the plurality of mirrors of the spatial light modulator is selectively set in one of a first state and a second state, the first state defined as a state in which light from an illumination system supplying the exposure light is reflected, the second state defined as a state in which the light from the illumination system is reflected so that the light from the illumination system has a phase difference with respect to the light reflected by the first state mirrors, and wherein\n the spatial light modulator is set so that the first state mirrors and the second state mirrors are alternately located.
