Abstract:
An exposure method for exposing a mask pattern, which includes plural types of patterns, with a high throughput and optimal illumination conditions for each type of pattern. The method includes guiding light from a first spatial light modulator illuminated with pulse lights of illumination light to a second spatial light modulator and exposing a wafer with light from the second spatial light modulator, accompanied by: controlling a conversion state of the second spatial light modulator including a plurality of second mirror elements; and controlling a conversion state of the first spatial light modulator including a plurality of first mirror elements to control intensity distribution of the illumination light on a predetermined plane between the first spatial light modulator and the second spatial light modulator.

Claim (Index 62):
An exposure apparatus that exposes an object with an exposure light from a light source, the exposure apparatus comprising:\n a polarization state setter arranged on an optical path of the exposure light from the light source to set a polarization state of the exposure light; a first mirror array arranged on an optical path of the exposure light from the polarization state setter, the first mirror array including a plurality of mirrors; a first optical system arranged on an optical path of the exposure light passing via the first mirror array to irradiate an illumination pupil with the exposure light passing via the first mirror array to form a predetermined light intensity distribution on the illumination pupil; a second optical system arranged on an optical path of the exposure light passing through the first optical system to illuminate an irradiated plane with the exposure light passing via the first optical system; a second mirror array arranged on the irradiated plane, the second mirror array including a plurality of mirrors; a projection optical system configured to project a predetermined pattern on the object with the exposure light passing via the second mirror array; and a controller configured to control states of the plurality of mirrors of the first and second mirror arrays.
