    摘要: A projection exposure apparatus and method having a projection optical system with a plurality of projection optical units and being excellent in matching between images formed through the respective projection optical units. First and second substrates are moved relatively to a projection optical system to project a pattern formed on the first substrate through the projection optical system onto the second substrate to effect exposure thereon. The projection optical system is provided with a plurality of projection optical units each forming a real-size erect image of the pattern formed on the first substrate on the second substrate. Each of the projection optical units has a plurality of reflective surfaces and is telecentric at least on an image side. The projection exposure apparatus also has a correcting mechanism disposed to correct an error of orientation between a plurality of images formed on the second substrate by the plurality of projection optical units.

    摘要: An illumination optical system which illuminates an illumination objective surface with a light from a light source. The illumination optical system includes a spatial light modulator which includes a plurality of optical elements arranged within a predetermined plane and controlled individually, and which forms a light intensity distribution in an illumination pupil of the illumination optical system; and a polarization unit which is arranged in a position optically conjugate with the predetermined plane, and which polarizes an incident light beam having a first and second partial light beams, coming into the polarization unit such that the first and second partial light beams have polarization states different from each other, and emits the polarized incident light beam as an outgoing light beam, wherein the polarization unit changes, in a cross section of the outgoing light beam, a ratio between a cross sectional areas of the first and second partial light beams.

    摘要: The present invention enables efficient decomposition without involving burdensome operations of carrying out decomposition of undecomposed pollutants discharged at the time of starting decomposition processing and undecomposed pollutants remaining at the time of interruption and termination of decomposition processing, separately from primary decomposition. At the time of starting decomposition, the steps of supplying a substance, which functions to decompose the pollutant, to a decomposition area, applying light to the decomposition area and supplying a decomposition target substance to the reaction area are carried out in the recited order, while at the time of ending decomposition, the operations of supplying the decomposition target substance, applying light to the decomposition area and supplying the substance, which functions to decompose the pollutant to the decomposition area are carried out in the recited order.
