    摘要: The immersion exposure device cleaning method according to the invention includes: placing a dummy wafer onto a stage of the immersion exposure device; and moving the stage while maintaining an immersion solution between the dummy wafer and a projector lens. The dummy wafer includes a substrate and an adsorption area that is formed on the substrate and has higher adsorption power for particles suspended in the supplied immersion solution than the substrate has for the particles.

    摘要: There is provided an apparatus used for forming a pattern on a substrate by photolithography with electron beams, the apparatus including (a) an aperture formed with at least one opening through which electron beams are to pass, and (b) a holder for fixedly supporting the aperture therewith by means an adhesive, at least one of surfaces of the aperture and the holder at which the aperture is adhesively fixed to the holder, being formed with at least one groove for excessive portion of the adhesive to flow in. When an aperture is fixed onto a holder with an adhesive, an adhesive may be excessively applied on a surface of the aperture or holder. However, in accordance with the above-mentioned apparatus, since excessive adhesive is pooled in the groove, it is possible to avoid the excessive adhesive from being forced out to the opening of the aperture, and thus, it is possible to avoid forming an incorrect pattern on a photoresist film.

    摘要: An electron beam exposure system has a continuous stage drive for driving a stage at a constant speed. Area of a semiconductor chip is divided into an array of unit meshes to calculate pattern density in each mesh. A group of meshes having an equal density level is combined as a sub-strip region having dimensions equal to or lower than the maximum width determined based on the ability of the electron beam exposure system.
