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.

A liquid immersion device that has an mixing mechanism that mixes and dissolves a predetermined substance for adjusting specific resistance of the liquid, which is supplied onto a liquid repellent film on the surface of an object (member) of a projection optical system placed on the light emitting side of projection optical system, and an liquid immersion area is formed by supplying the liquid in which the predetermined liquid is dissolved onto the liquid repellent film.

A spatial light modulator has a plurality of mirror elements each of which is controllable into a first state in which the mirror element reflects incident light with a change in a phase thereof by a first phase and a second state in which the mirror element reflects the incident light with a change in the phase thereof by a second phase 180° different from the first phase; and a boundary portion arranged between the mirror elements, which changes the phase of the incident light by a third phase substantially (90°+k·180°) (where k is an integer) different from the first phase. In projecting a pattern with the use of the spatial light modulator, an error caused in the pattern can be reduced even if the light quantity of light passing a gap region between the optical elements in the spatial light modulator is large.

An immersion type lithographic apparatus includes at least one immersion space and an immersion system configured to at least partially fill the immersion space with a liquid. The apparatus is configured to rinse at least part of the immersion space with a rinsing liquid before the apparatus is used to project a patterned beam of radiation onto a substrate.

An exposure apparatus includes an immersion space forming member (70) which fills an optical path space (K1) for exposure light (EL) with a first liquid (LQ) to form an immersion space, and a temperature regulating mechanism (60) which suppresses a change in the temperature of the immersion space forming member (70) accompanying deactivation of formation of the immersion space.

A method of driving a spatial light modulator includes: setting, in an array of mirror elements, mirror elements in a first state for turning incident light into reflected light with the same phase as that of the incident light or with a phase different by a first phase from that of the incident light and mirror elements in a second state for turning incident light into reflected light with a phase different approximately 180° from the first phase to an arrangement with a first phase distribution; and setting, in the array of mirror elements, the first mirror elements and the second mirror elements to an arrangement with a second phase distribution which is an inversion of the first phase distribution.

In a pattern forming method, a first L & S pattern is formed on a wafer; a first protective layer, a second L & S pattern having a perpendicular periodic direction to that of the first L & S pattern, and a photoresist layer are formed to cover the first L & S pattern; a third pattern having first apertures is formed in the photoresist layer to be overlapped with a part of the second L & S pattern; second apertures are formed in the first protective layer via the first apertures; and a part of the first L & S pattern is removed via the second apertures. Accordingly, a pattern including a non-periodic portion finer than a resolution limit of an exposure apparatus is formed.

An exposure apparatus exposes a substrate with exposure light that passes through a liquid. The exposure apparatus comprises: a porous member that has a first surface, which is capable of opposing an object disposed at an irradiation position of the exposure light, and a second surface, which is opposite the first surface, and forms a first space that is capable of holding the liquid between the first surface and the object; a supply port, which is capable of supplying the liquid to the first space; a prescribed member, which forms a second space that faces the second surface; an adjusting apparatus, which is capable of decreasing a pressure in the second space such that the liquid in the first space moves to the second space via holes in the porous member; and a control apparatus, which controls an operation of supplying the liquid via the supply ports and a pressure adjustment operation performed by the adjusting apparatus. The control apparatus repetitively executes a first operation, which supplies the liquid to the first space, and a second operation, which stops the supply of the liquid to the first space and negatively pressurizes the second space such that the liquid is substantially eliminated from the first space, to clean the porous member.

An exposure apparatus (EX) includes a setting apparatus (45) that sets an irradiation region (AR) of exposure light (EL) in a first state in which the irradiation light (EL) is irradiated onto a substrate (P) and irradiates, in a second state in which the exposure light (EL) is not irradiated onto the substrate (P), the exposure light (EL) onto a second region, which is different from a first region through which the exposure light (EL) passes in the first state, of a first surface of an optical member (FL) that is contacted with a liquid (LQ), to clean the second region by photochemical action.

An exposure method comprises: forming an immersion region on a substrate; exposing the substrate by irradiating the substrate with an exposure light via a liquid of the immersion region; and preventing an integration value of a contact time during which the liquid of the immersion region and a first region on the substrate are in contact, from exceeding a predetermined tolerance value.
