摘要:
The present invention relates, to an exposure method, exposure apparatus, and the like having a configuration for effectively preventing color inconsistencies from occurring due to defocusing upon scanning exposure. In particular, the exposure method and apparatus according to the present invention control the scanning exposure according to the positional relationship between a substrate and a detection area for detecting a focus state of the substrate, the positional relationship between individual shot areas on the substrate the positional relationship between a shot area on the substrate and an edge of the substrate, or the like.

An exposure apparatus comprises a substrate holding portion for holding a photosensitive substrate including a surface, a substrate stage for two-dimensional positioning of the photosensitive substrate via the substrate holding portion, the substrate stage including an upper surface, and an exposure system for transferring a pattern on a mask to the photosensitive substrate by an exposing illumination light. The substrate holding portion is provided in the substrate stage so that the portion of the upper surface of the substrate stage surrounding the photosensitive substrate is substantially flush with the surface of the photosensitive substrate.

With a scanning type exposure apparatus of the present invention, information of a target surface for alignment of a sensitive substrate in relation to the direction of an optical axis of a projection system is adjusted in accordance with at least one of a movement mode of a mask and a movement mode of the sensitive substrate, and based on reference information stored in a storage device, and scanning exposure is performed while aligning a surface to be exposed of the sensitive substrate and the target surface. Alternatively, an image formation surface of a pattern image of the mask is adjusted and scanning exposure is performed by aligning the image formation surface of the pattern image of the mask and a surface to be exposed of the sensitive substrate, thus enabling pattern transfer to be performed at a high exposure accuracy.

Disclosed is an exposure apparatus comprising a substrate holder washing unit and a substrate holder storing unit. While a substrate holder exported from an exposure stage is washed in the washing unit, a clean holder previously stored in the storing unit is transported to an X stage by using a robot hand and a transport arm, and it is installed to the X stage by using an attaching/detaching mechanism. The holder can be always maintained in a clean state without stopping the apparatus for a long period of time, resulting in improvement in throughput. Also disclosed is an exposure apparatus comprising a mechanism for cleaning a substrate holder by transporting a whetstone onto the holder, engaging the whetstone with an engaging member, and rotating the whetstone by using a rotary driving unit. The exposure apparatus is provided with a unit for drawing dust emerged upon cleaning with the whetstone.

To detect the height position of a substrate, a stop-plate having a plurality of slits applies light beams of elongated cross-section to the substrate obliquely. A sensor having a plurality of sensor elements receives light beams reflected from the substrate and outputs signals for controlling the height of the substrate. Additional light beams and sensor elements may be provided to output information regarding the direction of height deviation and the amount of height deviation.
